    Carbon frame bikes for racing

    Totally new to XC racing, but thinking of buying this machine due to a very nice price (1600): Optimum III

    My main concern is that as much as I love the idea of the carbon mtb HT, I'm thinking you may not race as fast over the technical stuff due to fear of falling and cracking the frame. Also replacing any of the components on the Optimum 3 would be savage. Hence maybe better sticking to a light (& cheaper) alloy, such as

    Any thoughts?

    As it's been said over and over, it's not the material that matters, it's the construction quality.
    Check out my SportTracks plugins for some training aid software.

    Okay, thanks, so what's the construction quality like of that Vitus I poseted. How much abuse will it likely be able to take before cracking/breaking the frame?

    I doubt anybody could actually tell you how much abuse any certain frame could take before failing. I can tell you that Giant offers a lifetime warranty on their XTC carbon, so I guess that gives an indication of how strong they think it is. How does the warranty from Vitus compare?

    Buying a new bike will rarely make you faster. You need to train more and at a greater intensity if you want to improve.

    A properly made Carbon frame is the most durable frame out there. I don't know anything about the bike you want to buy but the material it self is sound.

    Or to look at it another way... any impact big enough to break a carbon frame will also leave an aluminium frame severely compromised and in need of replacement.

    Most manufacturers have had issues with carbon frames on their learning curves to optimizing light vs. strong, but that's what warranties are for. Most of the same manufacturers had issues building light aluminium frames too. Most manufacturers are getting their carbon frames from the same few factories in Asia and they've had lots of experience now in avoiding design or material problems.

    Carbon. Totally normal. Most common material for ht race bikes these days...
