More anti-aluminum "facts"
In article .net,

Personally, I can look dispassionately at most any product I've purchased and explain the advantages and disadvantages. I have several aluminum frame bicycles, and I have one threadless headset bicycle, and was aware (somewhat) of the trade-offs when they were purchased. I probably would not purchase another aluminum bicycle simply because any new bicycle I get now would be a higher end product such as a Rivendell. I have had 2 aluminum bikes fail - both due to poor design in the area that failed and subsequently fixed in later models. One was failure of a cantilevered rear dropout on a Cannondale mountain bike. They wised up and don't make bikes with cantilevered dropouts anymore. Another failure was an '89 Trek 1200 - cracked all the way around the tube at a hole used for a rivnut for the front derailler (unreinforced holes in tubes are stress risers). Another bad design where the later model Trek bonded aluminums used a clamp on front derailler and no holes in the seat tube. On the subject of Rivendell, I read a report of steel frame failures (not Rivendell) where the crack started at the point of an ornate lug. Rivendell uses ornate lugs and touts that their bikes are built to last. I'm not saying they necessarily won't, but from an engineering point of view, the point of an ornate lug is a stress riser known to be the site of fatigue failure. I don't think material matters much - only design and construction. A mature design is better, so the lessons learned from failed frames results get incorporated into the later, same model product. I also won't buy a bike that does not have a lifetime warranty. -- Mike DeMicco (Remove the REMOVE_THIS from my email address to reply.) |

Advice Wanted: Bike Buyer in NYC
"Steven M. Scharf" wrote in message
snip It is indeed a shame that I don't have a bike store here with all the models I want to try. It's a small price to pay for living here though. I actually changed my mind about the Brava. I hadn't realized how heavy the steel construction was! I'm thinking about going back to my original choice, the Trek 1200 (2003). It's almost two model years behind now. Bike stores tell me the Trek 2005's will be out in June! The good news is the Trek 1200 (2003) is pricing around $700 ($750 with tax) at the stores I've checked. That's only $100 more than the Brava. The bad news is, it's hard to find one my size! Thanks again for all your reflections. Even if I'm not following your advice, I'm learning lots. |

Advice Wanted: Bike Buyer in NYC

2005's will be out in June! The good news is the Trek 1200 (2003) is pricing around $700 ($750 with tax) at the stores I've checked. That's only $100 more than the Brava. The bad news is, it's hard to find one my size! Whatever you do, don't compromise on the size. A great buy in the wrong size is a bike that will probably spend most of its time in the garage. --Mike-- Chain Reaction Bicycles www.ChainReaction.com |
