Syncros AM1.5 stem


UNUSUALLY, SYNCROS USE Torx T25 bolts throughout. These are less likely to round than conventional 4mm Allen bolts, but older/cheaper multi-tools sometimes lack the tool needed to adjust them. The recommended torque setting is a minimal 5Nm, which we found insufficient to stop the stem spinning on the steerer in our indoor tests.

It twisted after a small crash when out riding too. The bolts are heavily coated in threadlock, which is unnecessary and reduces the clamping force for a given torque. We found that we could nip them up tighter without issue though, which solved the twisting problem. The 45mm stack height is the tallest on test, which leaves less room for bar height adjustment but keeps things plenty stiff despite the low weight.
