    Newton Deda Stem on a XC Mountain bike

    Hi

    Bought a Newton Deda stem today got it for a bargain £30 my question is it strong enough for a xc mountain bike (gaint xtc 950) as it seems to be a road bike stem. I only do xc riding occasionally, mostly use my bike on the road.

    thank you

    You sure its the right clamp size? Standard road is 25.8-26.0mm while mountain is 25.4mm. If you got oversize (31.8mm) then you'll be OK there since both mountain and road are the same size.

    Problem with putting a 25.4 bar in a 26.0 stem is that your not getting even clamping force all the way around the bar. The bar is only being clamped at two points, which is a crushing force...and not safe at all. You can try using a homemade shim from a soda can...this can even the clamping pressure...but use at your own risk
