I wanted to buy a long cage rear derailleur for a touring/gravel bicycle I was building up for a friend. Just outside of town there's a guy who sells used bicycles in decent riding shape for $40 to $60. Seeing as a decent new long cage rear derailleur at any of the shops here in town cost at least $50 I decided to buy the $40 to $60 bike because then I got all those extra spare parts if I needed them for something else. A lot of the frames on the bicycles he sells are also decent cro-moly alloy ones or aluminium ones. Heck, I got one MTB from him for $20.00 that had all Shimano DEORE on it even if the groupset was an older one. I love the thumb-shifters on it because they can be set to friction as well as index and they are completely separate from the brake levers. The bike was in great shape but he hadn't checked it over yet which is why I got it for so little. Ditto with wheels. If I or someone I know needs a new wheel I often go to the out of town guy and either get a decent wheel for $10 or so or buy an entire bike for $40.00. Cheers I built a couple of bike that way. There are at least two dealers here that buy used bikes from Japan, I believe by the container load, and re-sell them. I bought what is probably a classic, except I can't identify the maker. The frame and forks weighed a few grams more than a frame that I had built out of Columbus SL tubes which is one of their lighter tubes.

With picture it is kind of hard to see details but it looks almost like they made the drop outs by mashing the tube flat and then cutting the axle slot. Not an inspiring way to make a quality bike :-) I wonder if Andrew could tells us if that happened enough that it's why we don't see that style anymore? I built that bike up with drop handlebars and old school external brake cable brake levers. Actually, they were suicide style brake levers but I took off the suicide levers, modified the pin that sticks out from the side and installed shift levers there. https://www.flickr.com/photos/738325...7669609219192/ https://www.flickr.com/photos/738325...7669609219192/ Cheers Cheers, John B. |

The end of the stay was thinned, squashed and welded, and the cantilevered drop out probably created some bending moment. I'm no engineer and don't know, and the failures could be explained by the way the stay-ends were designed rather than the dropouts. Harking back to the marketing thing, this is another example of the odd way bicycles are marketed. That is, a lot of claimed improvements are foisted on consumers and not chosen. I didn't choose the cantilever stay thing, but I did chose the Cannondale 2.8 because I was somewhat brand loyal, and the bike was a very good value. The components were well thought out, and it was a good riding bike for a big rider. I didn't choose BB30 or full internal headsets either. Those things were dropped on me when I got a later replacement frame from Cannondale. I don't think anyone bought a Cervelo because it has BBright or that anyone goes into a bike shop and says, "say, show me the BB86 bikes." I've never thumbed through Velo News, lusting after the the latest BB30A. I might like the look of the matching (required) crank, but I'm cringing at the thought of getting yet another BB format. -- Jay Beattie I suspect that the real reason for the 1-1/8" head sets and the press in BB's is largely to make it cheaper to build the frames. Certainly the machine and fitting to make the old style head set cost more then just slapping in an extra spacer or two, and boring and threading the BB involves one more step in manufacturing. While this doesn't sound like much, and of course the volume is different, but I remember an engineer who had worked for Ford telling me that he once got a cash reward for demonstrating a method of eliminating two sheet metal screws from the firewall and this saving several pennies in cost per car manufactured.

Truth be told, I don't use 'em that often, so the velcro stays "closed" and has little opportunity to collect crap (dog hair in my house). But my sense is that these (and similar straps w/o D-ring from the same sourse) haven't picked up too much lint in the 3-5 years I've had them. Thing is, they're so light and roll up so small, you forget they're there until you need 'em. Contrast (IMHO) toestraps that take up a fair amount of room in a seat bag Mark J. |

Truth be told, fear of an ugly mess (even if due to operator error) makes me uninterested in trying.

Bikes and bike parts are a super-mature industry, and bikes and their products last decades. (My favorite bike is from 1986.) So the industry tries to come up with new ideas every year, just to entice you to buy _something_. Going back to the 1970s, it was "Ten speeds!" then "Touring bikes!" then "Aluminum!" then "Mountain bikes!" ... and on and on, with front suspension, full suspension, 6 speeds, 7 speeds, 8 & 9 & 10 & 11 speeds, carbon fiber, electronic shifting etc. It goes on forever. Currently it's disc brakes, tubeless tires and "gravel bikes." For almost everyone who rides a bicycle, the improvements (if any) are almost undetectable. We are deeply into diminishing returns, no matter what miracles the supposed connoisseurs claim. I take issue.* Indexed ergo shifters vs downtube friction shifters, LED LiPo lights vs dodgy glow worms, and this is going to cause trouble, yes, hydraulic discs vs cable rim brakes. I think Tosspot has nailed it here, though Frank's not wrong either, in large part. Yes, those of us who have watched cycling's new products for a while (~40 years for me) know that there's a lot of useless junk that shows up.* There are also some great improvements, and some wonders. While we will disagree about some (many) of them, let's admit that available products today include a lot of great innovations. But here's the thing - at first it was hard to tell which area of "improvement" would really work.* I think most of the categories of improvements we enjoy today had early failures - hilariously so in some cases, and they were surrounded by other "categorical failures", ideas that really turned out to be entirely useless. Here's a partial list (according to me) of big improvements I've seen that weren't obvious in their first appearance: Low-cost aluminum... cranks, derailleurs, etc. I worked episodically in a Raleigh shop in the later 70's, assembling new bikes.* Right about then Raleigh shifted from lots of steel (or plastic) Nervar, Simplex, Huret stuff to aluminum Sugino, SunTour, and SR stuff.* The latter was vastly easier to set up well.* But there was junk (plenty of it?) in the cheap aluminum component category.* I remember a cottered aluminum crank (!).* In the earlier 70s, I doubt we would have thought that low-cost aluminum parts could ever be good. Quality clincher tires (first decent ones, then great ones). When I started riding, no clincher came close to the quality, rolling resistance, weight of sewups, pain-in-the-ass though they are. Then SBI (Specialized Bicycle Imports, later shortened), IRC, and then Michelin started selling very nice clinchers, and Schwinn's outsourced "LeTour" tires were good too.* Today I can get "handmade" non-vulcanized tires by Challenge, Veloflex, or major brands like Vittoria that come pretty close to duplicating sewup feel, rolling resistance, and (almost) weight.* Or I can get midweight vulcanized tires that are only slightly heavier. But some of the earlier attempts at "clincher reform" were, IIRC, pretty crappy.* One could easily have thought that "quality clincher" was a pipe dream that would never take root. Clipless pedals This one is huge for me.* When I had toestraps tightened enough to work - and I kept 'em pretty loose - I still had killer problems with cold feet in winter.* With clipless, I have lots of room for shoe covers, etc., not to mention other advantages.* I know we don't all agree, but the overwhelming adoption of clipless can't /just/ be marketing. BUT OMG were there a bunch of poor, crappy, and even disastrous/dangerous clipless designs early on.* Sampson comes to mind, or especially the Cinelli M71 pedal.* I've forgotten the names of most of the others, but they certainly gave the impression that clipless pedals were crazy. Indexed shifting Again, we don't all agree, but the overwhelming majority of cyclists seem to think that index shifting is a pretty neat idea.* Despite some real turkeys early on (Positron and Positron II, anyone?), turkeys that "clearly" signaled that index shifting was an answer to a question nobody asked, it turns out you *can* make a quality indexed shifter. Who knew? I could go on.* Brifters, LED/LiPo lights, aluminum and carbon frames, bicycle computers, nylon saddles (that's reaching back many years), and yes, disc brakes, etc. - and all those advances coming on the scene with many poor early designs, and surrounded by junk we still laugh about that never amounted to anything.* But if we could tell which inventions would blossom when we first saw them, we'd all have invested in Intel and Microsoft in the 70's and be rich now. So even though I agree with Frank about "churn" in large part, that churn turns out a few not-immediately-recognizable innovations that most of us are glad about.* A sort of Darwinian evolution, if you will. While the industry may be super-mature, it ain't done yet. Mark J. I can remember when BIYCLING magazine had an article about NOT needing 15 gears on a bicycle. They stated in their article that 10 gears was more than enough. I've tried clipless pedals but had problems getting out of them at times and then falling over and getting scraped up a bit. Therefore I went back to toeclips. For most of my riding I don't even have to snug up the straps let alone tighten them up yet my feet stay on* the pedals. Besides, toestraps have LOTS of other uses. I've used one to keep a dressing on a cut on a leg. I've used them to secure a jacket and tights to the underside of my saddle after the temperatures rose to from quite chilly to quite warm. I've used a toestrap to secure an extra water bottle under a saddle. I've looped a toestrap around my handlebar and stem and used it as makeshift bottle holder to hold a* cup of coffee. I used 2 toestraps joined together to hold something to the rear rack on a bicycle. Hard to do any of that if you have clipless pedals. LOL VBEG ;) I can remember too when downtube shifters sometimes would wear, or at least the innards would, to the point where it was nearly impossible to keep in the gear one wanted. I think pneumatic clincher tires with separate tubes, decent derailleurs and decent index shifting are 3 of the major innovations that caused bicycling to grow as much as it has in North America. I like my Campy Ergo 9-speed shifters on my touring bike. The left shifter is ratchet and thus it's dead simple to trim the front derailleur. I find I shift more often on hills with a load with the Ergos t han I did even with bar-end shifters. However, I still like my downtube shifters that i have on some of my other bikes. I especially like my top-center mounted Dura Ace AX shifters and my top-center downtube mounted Suntour symetric shifters (?) because they can be shifted front and rear with just one hand at the same time. In winter I really like my Lyotard MB23 platform pedals*. They're Frank's favourite pedals. For me and for many others even 7 gears in t he rear with 2 or 3 chainrings is plenty. I like Shimano 9-speed clusters because I can set them up with 7 cogs for most riding but with 2 larger cogs for bailout gears. I use a Campy Ergo 9-speed shifters and rear derailler to shift my 9-speed Shimano cassette on my touring bike. Some folks who are really into fitness riding or fast-paced group riding probably love more gears because the increases in effort between gears isn't as great as it is in 7, 6, or 5 speed cassettes. Again a lot of bicycle innovations are different horses for different courses. At least now we have a lot of equipment choices that can be used to give us the customized bike we WANT or NEED for OUR style of riding. That last sentence says it all. -- duane Something the 'dinosaurs' will never understand and claim everone is a victim of marketing. Of course, there are innovations and improvements. And of course, any given improvement will matter to some people more than others. But I think it's naive to pretend that all (or even most) changes are significant improvements, or to pretend that marketing isn't a big part of what drives purchases. I also think it's naive to attach the label "dinosaur" to people who realize all this. Do you mock people who don't have tattoos? No mocking here, but a serious question. Do you see a lot of pretense (beyond the marketing, e.g. Buycycling magazine) that all these changes /are/ big improvements? Maybe I'm too deeply mired in my own cynicism, but I always thought that most folks knew to discount 99% of marketing. Sure, there's a sucker born every minute, but are you meeting a lot of them? Again, intended as a serious question. Mark J. Re Bicycle Magazines. It seems to me that "way back when" bike magazines used to have articles that actually told one something. The first time I was actually told the best way to set up a road bike, i.e. how far back and how high to set the seat for best results, was in a magazine. I remember one of their recommendations was to always to wear a tee shirt under your jersey. This allowed the jersey to slide on your tee shirt rather than on your skin and would help to prevent road rash :-) Now, they seem to be a series of product evaluations thinly masked as "tests" that always seem to glorify the product being tested.

But here's the thing - at first it was hard to tell which area of "improvement" would really work.* I think most of the categories of improvements we enjoy today had early failures - hilariously so in some cases, and they were surrounded by other "categorical failures", ideas that really turned out to be entirely useless. Here's a partial list (according to me) of big improvements I've seen that weren't obvious in their first appearance: Low-cost aluminum... cranks, derailleurs, etc. I worked episodically in a Raleigh shop in the later 70's, assembling new bikes.* Right about then Raleigh shifted from lots of steel (or plastic) Nervar, Simplex, Huret stuff to aluminum Sugino, SunTour, and SR stuff.* The latter was vastly easier to set up well.* But there was junk (plenty of it?) in the cheap aluminum component category.* I remember a cottered aluminum crank (!).* In the earlier 70s, I doubt we would have thought that low-cost aluminum parts could ever be good. Quality clincher tires (first decent ones, then great ones). When I started riding, no clincher came close to the quality, rolling resistance, weight of sewups, pain-in-the-ass though they are. Then SBI (Specialized Bicycle Imports, later shortened), IRC, and then Michelin started selling very nice clinchers, and Schwinn's outsourced "LeTour" tires were good too.* Today I can get "handmade" non-vulcanized tires by Challenge, Veloflex, or major brands like Vittoria that come pretty close to duplicating sewup feel, rolling resistance, and (almost) weight.* Or I can get midweight vulcanized tires that are only slightly heavier. But some of the earlier attempts at "clincher reform" were, IIRC, pretty crappy.* One could easily have thought that "quality clincher" was a pipe dream that would never take root. Clipless pedals This one is huge for me.* When I had toestraps tightened enough to work - and I kept 'em pretty loose - I still had killer problems with cold feet in winter.* With clipless, I have lots of room for shoe covers, etc., not to mention other advantages.* I know we don't all agree, but the overwhelming adoption of clipless can't /just/ be marketing. BUT OMG were there a bunch of poor, crappy, and even disastrous/dangerous clipless designs early on.* Sampson comes to mind, or especially the Cinelli M71 pedal.* I've forgotten the names of most of the others, but they certainly gave the impression that clipless pedals were crazy. Indexed shifting Again, we don't all agree, but the overwhelming majority of cyclists seem to think that index shifting is a pretty neat idea.* Despite some real turkeys early on (Positron and Positron II, anyone?), turkeys that "clearly" signaled that index shifting was an answer to a question nobody asked, it turns out you *can* make a quality indexed shifter. Who knew? I could go on.* Brifters, LED/LiPo lights, aluminum and carbon frames, bicycle computers, nylon saddles (that's reaching back many years), and yes, disc brakes, etc. - and all those advances coming on the scene with many poor early designs, and surrounded by junk we still laugh about that never amounted to anything.* But if we could tell which inventions would blossom when we first saw them, we'd all have invested in Intel and Microsoft in the 70's and be rich now. So even though I agree with Frank about "churn" in large part, that churn turns out a few not-immediately-recognizable innovations that most of us are glad about.* A sort of Darwinian evolution, if you will. While the industry may be super-mature, it ain't done yet. Mark J. I can remember when BIYCLING magazine had an article about NOT needing 15 gears on a bicycle. They stated in their article that 10 gears was more than enough. I've tried clipless pedals but had problems getting out of them at times and then falling over and getting scraped up a bit. Therefore I went back to toeclips. For most of my riding I don't even have to snug up the straps let alone tighten them up yet my feet stay on* the pedals. Besides, toestraps have LOTS of other uses. I've used one to keep a dressing on a cut on a leg. I've used them to secure a jacket and tights to the underside of my saddle after the temperatures rose to from quite chilly to quite warm. I've used a toestrap to secure an extra water bottle under a saddle. I've looped a toestrap around my handlebar and stem and used it as makeshift bottle holder to hold a* cup of coffee. I used 2 toestraps joined together to hold something to the rear rack on a bicycle. Hard to do any of that if you have clipless pedals. LOL VBEG ;) I can remember too when downtube shifters sometimes would wear, or at least the innards would, to the point where it was nearly impossible to keep in the gear one wanted. I think pneumatic clincher tires with separate tubes, decent derailleurs and decent index shifting are 3 of the major innovations that caused bicycling to grow as much as it has in North America. I like my Campy Ergo 9-speed shifters on my touring bike. The left shifter is ratchet and thus it's dead simple to trim the front derailleur. I find I shift more often on hills with a load with the Ergos t han I did even with bar-end shifters. However, I still like my downtube shifters that i have on some of my other bikes. I especially like my top-center mounted Dura Ace AX shifters and my top-center downtube mounted Suntour symetric shifters (?) because they can be shifted front and rear with just one hand at the same time. In winter I really like my Lyotard MB23 platform pedals*. They're Frank's favourite pedals. For me and for many others even 7 gears in t he rear with 2 or 3 chainrings is plenty. I like Shimano 9-speed clusters because I can set them up with 7 cogs for most riding but with 2 larger cogs for bailout gears. I use a Campy Ergo 9-speed shifters and rear derailler to shift my 9-speed Shimano cassette on my touring bike. Some folks who are really into fitness riding or fast-paced group riding probably love more gears because the increases in effort between gears isn't as great as it is in 7, 6, or 5 speed cassettes. Again a lot of bicycle innovations are different horses for different courses. At least now we have a lot of equipment choices that can be used to give us the customized bike we WANT or NEED for OUR style of riding. That last sentence says it all. -- duane Something the 'dinosaurs' will never understand and claim everone is a victim of marketing. Of course, there are innovations and improvements. And of course, any given improvement will matter to some people more than others. But I think it's naive to pretend that all (or even most) changes are significant improvements, or to pretend that marketing isn't a big part of what drives purchases. I also think it's naive to attach the label "dinosaur" to people who realize all this. Do you mock people who don't have tattoos? No mocking here, but a serious question. Do you see a lot of pretense (beyond the marketing, e.g. Buycycling magazine) that all these changes /are/ big improvements? Maybe I'm too deeply mired in my own cynicism, but I always thought that most folks knew to discount 99% of marketing. Sure, there's a sucker born every minute, but are you meeting a lot of them? Again, intended as a serious question. Mark J. Re Bicycle Magazines. It seems to me that "way back when" bike magazines used to have articles that actually told one something. The first time I was actually told the best way to set up a road bike, i.e. how far back and how high to set the seat for best results, was in a magazine. I remember one of their recommendations was to always to wear a tee shirt under your jersey. This allowed the jersey to slide on your tee shirt rather than on your skin and would help to prevent road rash :-) Now, they seem to be a series of product evaluations thinly masked as "tests" that always seem to glorify the product being tested. Cheers, John B. I would be much more likely to buy something advertised in those magazines if at least one review per issue said "This product is crap. We can't in good conscience advise that you buy it." Alternatively, if "Every product is great!", then why do I need to read the reviews in the magazine? |
