Defective bolt
- Familiarity:
- I've used it once or twice and have initial impressions
It’s fine for a lightweight stem, but FSA seemed to have skimped on bolt quality. I broke one as I was torquing it to spec at 6Nm (it broke at 4Nm). I had to drill out the broken bolt and luckily I had an extra one lying around that fit. If I hadn’t had an extra, this would have been a return for a defective item. Hopefully BC can send me a replacement bolt that matches the others.
