Gravity Gap OS stem review£44.95

Burly but without excess heft

BikeRadar score3.5/5

This sturdy little beast only weighs 159g in its shortest length (45mm) which is impressive for its burly build. We quite like the matte black, stealth finish and minimal logos. Although the 4mm bolts help to keep the weight down, we had no issues getting the bar tightened up nice and tight.

When it comes to stiffness, the Gap OS is right up there with the best of them and the rise felt comfortable too, making it a good all-rounder. Using 5mm bolts rather than 4mm would make it easier to get it tight at the steerer. Torque setting markings would also be handy too.
