Gads! $329.99?! Wow! No thanks. I'll stay with the FAR LESS expensive retro offerings.

Cheers

But you also get Earn 1649 Reward Points :-)

Right, reward points. VBG ;) However I could get 5 pairs of the $60.00 MKS pedals shown in the other link and still have money left over. Are those $329.99 pedals THAT much better?

Cheers

Come on Man! They are new.

They have a "classically inspired profile combined with modern
materials and design is ideally suited for the urban cyclist. These
pedals provide the perfect platform for whatever shoes you decide to
ride in." And! They are made in the USA! None of that cheap foreign
made stuff.

They are available in both silver and black anodized finishes and the
bronze acorn nuts add a touch of class

I'm surprised that everyone isn't buying at least two :-)


Cheers,
John B.

Hi John. It seems to me that a lot of the newer stuff for bicycles isn't so much about function or even looks but how high the cost for it can be.. LOL Is that the new criteria for bicycle stuff = high cost?

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.

The guy also had some bare unpainted road bike aluminum frames,
sloping top tube, very modern looking stuff, that he was selling cheap
but at the time I wasn't interested in aluminum so I passed on them.


Cheers,
John B.


The guy I deal with also had an older Cannondale MTB with rear dropouts that extended beyond the frame. Interesting. I figured that under really hard riding that they'd be prone to breaking off.

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.

I noticed the Summit sticker. Local company. But not much for bike
parts, AFAIK.

The sticker was on it when I bought it from the guy outside of town. I thought that it was a company that made bicycles but someone told me that Summit is a racing car sponsor or something to do with auto r acing.

The shifters in the place where the suicide lever used to attach work quite well.

Cheers

steel ones rust after a while. So I mentioned those.

I didn't get any. :-(


I bought the brass pins that I secure my ankles with at Walmart; I
think it was in the crafty-wafty department.

They are rather coarse, but I use them only with cheap sweat pants.

I like them mainly for the looks; under conditions that make steel
pins rust, brass would turn green, stain your clothes, and be hard to
pull out.

Count me in for the carbon-fiber safety pins -- if they come in
International Orange, they would be much easier to find when I drop
one.

Another wish list: safety pins of *any* material that say on the
package how thick they are. I'd love to have silk pins with a safety
catch on them.

("silk pins" are a thin variety of dressmaking pins. They used to be
nickel-plated brass, but are now stainless.)

As long as I can remember, "brass plated" pins have been available,
usually in the very smallest size, presumably to make them easier to
find in a box of mixed pins. When I grew up, I began to wonder how
one plates with an alloy -- brass melts too high to "hot dip" as one
does with zinc -- and it just now occurs to me to wonder how one goes
about brass plating something as cheap as a safety pin.

Electroplating. You put the parts into a bath containing stuff
(cyanaide compounds historically, often less toxic stuff these days), use a
brass anode, and apply a current. Details vary, but that's used for
all sorts of thin coatings.
