We have updated the dumbbell holder to fit the new seat carriage assembly and seat stem holder. Please check your bike serial number before ordering a dumbbell holder to ensure you order the correct part.
Bikes built with a serial number lower than A071519xxxx require the original dumbbell holder (long), 971-0153. Bikes built on or after A071519xxxx require the new, short mount dumbbell holder, 971-0146.
