We’ve beefed up our Trainer Flex Mount so you can get your laptop in position to put the hammer down on your rivals on Zwift or whichever program you use for your suffering. Two of our easy-on/easy-off handlebar clamps keep it all locked in place, two 7″ flexible arms let you position your laptop just right, and one powerful 6″ SeaSucker vacuum mount attaches under your laptop. Handlebar clamps fit 31.8mm diameter bars only!
