the 2020 BMC Teammachine SLR 01 Disc One is a formidable machine, and when paired here with the top line Shimano Dura-Ace Di2 groupset it might just have raised the bar again. The asymmetric frame is light, stiff and yet also compliant delivering a ride experience that is predictable and balanced, so whether you are dancing on the pedals up climbs or charging into a hectic sprint, the power transfer is right there where you need it.
