This may be the only negative stem review ever. I have a syntace megaforce 2 40 mm stem. Today riding to work, I went down a few stairs and the bars twisted out of straight with the fork. Meaning the stems clamp on the steerer tube slipped. I checked the torque on the bolts, 8 NM just like specc'ed. What. The. F#%k. Imagine if that happened on one of the 4 dh's i rode the other day. ive had it for 6 years, but it has a 10 year warranty. But their warranty is they just replace it, and now i dont trust syntace. Found a raceface respond 45 mm stem in my parts bin, close enough!
