My Favorite Threadless Stem

If you don't like this stem don't follow me on Instagram. Cleanest/nicest 1 1/8" stem for the cyclist who's not afraid to sit up like an adult.

Beautiful, retro-styled stem

I have a lot of vintage French bikes with what I consider to be just about the ideal styling. I recently acquired a new-ish all-road frame with a threadless fork and wanted a more traditional look to it - the tall stack stem was just what I needed! I got the 17-deg stem to match the 73 deg head tube angle and it made for a clean, classic look.

Awesome, and A+ customer service

I've been looking for something like this with the quality you made it for years. Perfect score. I'll buy from you in the future if I need anything that you sell.
