Bought to replace my 428 set. Big improvement in gearing and it’s lots smoother now! Bigger sprockets, chunkier chain = better looks. Really happy with the purchase, thanks Marcel!

Straight swap, easy fit. Looks great. Will post pictures later. Bigger front and rear sockets, longer thicker chain. I am perfectly happy with my purchase and hand delivered by Marcel. Excellent product, great store. Will be using again

Bought for 2016 GT. Straight forward swap out. Bike feels better geared in all gears. No massive top end gains but worth it for the increased rideability!!
