Carbon Bike

Betty Biker2011-03-09 17:23:00 +0000 #1
I recently purchased a full carbon bike. The manufacturer (Cannondale) says not to use fork type carriers (the frame rests on two extended arms). The folks I purchased the bike from and other sellers in my area said they never heard of problems with these type of carriers. What is your experience? Should I use another carrier? If so, what type?

Thanks

When I replaced the fork on my old road bike, I put a carbon fork on it that had carbon dropouts, as opposed to alloy drop outs (the drop outs are the half-circles that attach to the wheel at the hub). I was also told to not use a fork-mounted bike carrier like this: yakima.com/shop/bike/top/sprocketrocket , and to use an upright carrier, more like this: yakima.com/shop/bike/top/raptor .

Perhaps it is primarily a CYA move on the fork/frame manufactures part, but I took them at their word - so as not to put huge and unwarranted stress on delicate parts. So, I use a rear hitch mounted upright carrier: www.thule.com/en/US/...itch/916XT%20T2.aspx .

Can i ask why you're not supposed to use the fork-mount racks? i have a carbon fork on my road bike, and use the fork-mount roof rack....and now you have me nervous.

I would guess that it's just because so much stress would be put on such a small area... and I guess the stress from a roof rack is different enough from the stress of normal usage. I have a carbon fork on my road bike, but it has alloy dropouts, so I was told by the LBS that it was not a concern with my roof rack.

I have used a roof rack with fork mounts on both of our carbon bikes for years without a problem. I think the key is to not yolk it down to hard or tight where you could crack a dropout? Thats my guess.
