Without a second chainring the tube transitions to the BB are no longer compromised. Now symmetrical the bottom bracket is perfectly balanced with the downtube and chainstay contributing to 30% greater lateral stiffness.
Another advantage of a symmetrical bottom bracket is better engineered chainstays and seatstays. New tube profiles provide greater directional stiffness where needed and just the right amount of flex for overall comfort.
Everything you need for road and off-road.
With 11 speed Shimano. Steady climbs, steep climbs or going fast, a 1x drivetrain delivers everything a 2x does and with less mechanical issues.
