With revolutionary advancements in bicycle componentry, like SRAM’s XX1, X01 and X1 drivetrains, mountain bike designers have been given almost limitless freedom to focus solely on the performance of the bike. Each advancement demands that the entire package works flawlessly. Aggressive trail and enduro riders have been increasingly enjoying the benefits of larger wheels, but many still view 27.5" and 29" wheels as a possible weak link.
