Mr BainesAmazing piece of kit which is dead easy to fit and setup. Basically just works like a dream and is turning out to be Yorkshire weather proof so far.
Mr BainesWhat an amazing piece of kit. Fast changes and just encourages you to keep changing gears. Perfect for time trial bikes when combined with the triathlon DI2 switch set and triathlon DI2 STI lever set. Set and forget. I'll never use cable shifters on my time trial bike ever again
