Im going to purchase a new chainset for my AM bike. Now, Ive seen the one im after on a well known site thats £35 cheaper than anywhere else but its 165mm.

My current set has 175mm arms which is what im used to riding on this type of bike. If it helps, I have a 33" inside leg.

I also have a DH bike with 165mm crank arms and I cant say Ive noticed much difference apart from the obvious benefits of clearance, but then this bike is used differently to my other.

Will I actually notice that 10mm difference on the trails etc?

Thanks for any advice, Carl.

    Ok, thanks for the reply.

    Just thought I could have saved some money there.
