I've got a library of 35mm clamp stems including 35, 40, and 50 lengths to play with fit. I'd like to fill in the gap between the 40 and 50mm. I see Spank makes a 45mm length option, however, it's a split clamp design; more fiddly, imo. I prefer a single piece faceplate. Fairly ambivalent on the stack and rise, though low stack is nice.
Any other options out there?
