Carbon frames and heavy riders

edited August 2008 in MTB buying advice
I'm in the market for a full sus, and the Cannondale Rush 4 is on my list of potential bikes.

I weigh 16.5 st, and while i know the frame wont break the moment i sit on it, i'd like to know how a carbon frame will perform under my weight over time.

Are carbon frames more suited to lightweight race whippets?

Am i best going for the aluminium framed Rush 5?

    Forgot to add: I don't do any jumping and i'm sure the frame wouldn't cope with that anyway.
    My riding involves mainly trail centres: Llandegla, Coed Y Brenin, etc

    I wouldn't think you'll have any problems with your size and weight on a carbon frame
    Don't forget that aluminium frames have "joints" where they weld the sections together, they would surely be the weak point of any frame.
    I have a mate who is about 6'7" and weighs about 20 + stone. He has an XXL Scott Genius. Yes he has had a few problems with the bike (Tearing the back sprocket out due to his power) but no problems with the frame.
    I would imagine that if there were any issues it would come under manufactures guarentee any way

    I've downloaded the User Guide from the Cannondale website. Nothing about rider weight limits in there.

    I also add the carbon scott bikes are definately worth a look!
  • About Scott Carbon bikes I think they are rated for riders up to 120kg

    That is a 120kg rider THRASHING it.

    I'm 13 stone and tend to break bikes (not jumping either). I would buy alu. if I'm honest.
