Original Cannondale OPI stem for Lefty. Requires use of KH078/STD steer tube sold separately. KH078/STD works only with Lefty 1.0 forks on bikes with 134mm headtube spacing.

These OPI stems can work with F-Si, Scalpel Si, and bikes with Lefty 2.0 forks but require a shorter steer tube not produced by Cannondale.

Stem in photos is 100mm length as an example only.

Kit includes one stem with faceplate and four bolts and one thin nylon shim. Does not included spacers needed to get correct height.
