In this week’s Tech in Motion, Dan Cavallari puts the promise of the best carbon braking to the test with Mavic’s Ksyrium Pro Carbon SL wheels. In the interest of (very) marginal gains, he pairs those wheels with SLF Motion’s Hyper pulley wheels, which are designed to help reduce drivetrain friction and thus save you watts.

And finally, Donkey Label’s Unisex Base Layer shouts “look at me” with an interesting aesthetic, but what else has it got up its (forward-rotated) sleeves?
