With its super-short steerer clamp height (33mm) and 5mm of rise or drop (depending on which way up you run it), the Defy offers lots of options for experimenting with bar height.
DMR’s unusual ‘Top-Close’ clamp allowed it to twist on the steerer more easily than most of the stems here in our static test, even with the bolts tightened to the 6Nm maximum torque. The short stack also introduces more flex during standing sprints. At 187g it’s the second heaviest stem on test. It’s only available in a single 50mm length.
