sdcycling said:I don't think that weight is the issue. I think that the manufacturers are supplying forks with carbon dropouts because it is easier to build than carbon forks with alloy dropouts. Meanwhile, I had the used fork that Look sent to me checked out at a Look dealer. They think that it is cracked. I cannot believe that Look sent me an used fork. Also, I consider myself pretty lucky in that the fork did not fail while I was going down some steep hills. I hope that Look makes this right. If you poke around on the web, there are some discussions about the durability of carbon dropouts. Also, some skewer manufacturers specify that their skewers should not be used with carbon dropouts. I think that wear issue will become more of an issue over the next year or so as other riders start to have problems with carbon dropouts. Hopefully, no one gets hurt or worse in the process.
I don't understand how putting wheel in wheel can cause wear. Wouldn't this happen to aluminum dropouts too? Look hsc5 has carbon headset race. Trek has carbon bottom bracket race they claim harder than steel. http://www.trekbikes.com/madone/technology/efficiency/California L33 said:That doesn't seem right. Didn't your Look come with a manual? I've never seen _anything_ about not tightening skewers on carbon dropouts. My only carbon dropout bike came with exactly the same warning as my metal dropout bikes- paraphrasing here so I don't have to get it- 'tighten the quick release dropouts as hard as you can while hand closing. If you don't see a mark in your hand from the lever after closing it isn't tight enough and the bike is dangerous.'
That said, I don't like carbon dropouts. They do seem to wear when putting wheels in. Is it that hard to put a metal pressure plate in them? Does it add that much weight?
