    Carbon forks

    I'm curious if anyone has feedback on carbon forks for heavy riders. Looking at a new cross frame to replace my old steel cross bike. The bike I'm looking at happens to come with a carbon fork. I have to admit that as a heavy rider, a carbon fork breaking on my daily commute scares me a little. Anyone 250+ have experience going down this road?

    I am usually in the 240-250lb range and have about 2500 miles on my current carbon fork. No problems so far.

    If you buy a carbon fork suited to cyclocross, you shouldn't have any problems. If you buy a spindly 100g model designed for the Tour de France, then I'd start to worry...

    I've got a total of about 50,000 miles on 3 bikes with carbon forks at 220-245, no problems. I wouldn't go with a superlite setup though, just my opinion and sense of safety (but that's on any component).

    Funny, everybody worries about carbon but only thing that has failed on me was an aluminum frame.....besides wheels that is.

    I ride a carbon fork. I actually ride a carbon/aluminum frame. The bond points in the frame scare me but the carbon fork hasn't crossed my mind once, and I am 290.

    I weigh ~235 and have three bikes with carbon forks and no problems. oldest carbon fork is 5-6 years old.
    I don't do vintage, I bought them new, rode them, kept them. Now they are just old bikes

    300 with a carbon fork/aluminum steer tube....no problem it is an EC-70. I emailed the manufacturer and asked them about weight limits...none on the EC-70

    Don't worry. The fork doesn't bear your weight until you brake. I've been as high as 300 on an aftermarket Nashbar CF fork.
    Bikes use brakes to stop.

    If your bike has breaks, don't ride it.

    Oh, just curious... the carbon folks that you all are talking about, is the steering tube steel or aluminum? The one in question is aluminum.

    The steerer on mine is steel, but I was limited due to the 1" threaded headset I have.
