If you’re concerned with winning, this is the bike for you. If you’re concerned with value, it is not.

Who doesn’t like riding fast? The Fourstroke offers exceptional speed in every situation backed up with the soothing stability and control from geometry that is a world away from old fashioned XC bikes, plus the integrated dropper is a real highlight and a benefit on rowdy terrain when you’re riding on the limit.

BMC Fourstroke 02 XT first ride review

Oct 2017 · Rob Weaver

It’s eager to get going, and while this isn’t the lightest build on offer, the frame stiffness and composed suspension feel under power mean you’re up to speed in no time. . .
