Okay guys, I'm looking for threadless stems with the clamp bolts that don't hang off the back, i.e. threadless stems that have a smooth butt. Only examples I have found are the Cinelli Alter, Cinelli Sesamo, Deda Zero Nero, Thomson Elite, and Look A-Stem and one by Velo Orange. I'm looking for something with mad tyte pursuit angle yo. Anyone know any others?

I suppose the clamp bolts on the back would be okay if the whole back end is smooth.

I hestitate to reveal my reasons, but I'm looking at doing a stem/headset treatment a la Cinelli Laser Evolution / 2012 Look 986 RSP. And it's a lo-pro. That's all I want to say for now. Any suggestions? Would like to avoid converting to a quill stem.

any excuse to post pics of the alter, amirite?



Don't worry about sizes so much right now, I want to put everything on the table. The bike is going to be custom built so I have options.

RaceFace Prodigy if you can find one.

cash put in the hands of a frame builder can get something created..
