The publications claim it's a winner, the reviewers write that it's a winner, and professional podiums the world over silently affirm that it is, in fact, a winner.

It also eliminates the failure prone rear shock bushing while taking full advantage of the DW Link suspension's ability to balance travel with chain tension for a consistent, stable pedaling platform that's anti squat, ...
