The alu Beargrease is an awesome bike. If you are a premier user, I penned a review on the front page.
Would I want a carbon one? To be honest, the Beargrease is already a very light bike such that I’m using it for general riding and don’t feel the need to lighten it up. If I did, I’d be opting for XTR as my experience of the new ten speed SRAM kit is that it doesn’t have the longevity of Shimano kit. Shame about the press fit bb on the carbon frame. I’m gradually growing to really dislike press fits. I can’t say I notice any increase in stiffness over an old square taper design while the bearings seem to last an even shorter time than ISIS <shudder>. 😯
Of course, I’ll still want to try riding one 😀
Cheers
