Questions

Marcus

I have a slope-cut steer tube with the lowest side at 35mm. Can I still use this stem if I flat-cut the steerer tube to 40mm (there will still be a small part that slopes to 35mm)?

Hi Marcus!
The mid-point of the top steerer clamp bolt is the lowest point you should have your steerer tube level with, and that is 32mm on this stem. As long as you have your steerer above that you shouldn't have any problems, even if it isn't all cut flat.
If you have any more questions, please ask!
