Friction shifters are the most reliable way to change gears, bar none, and these are the most advanced there's ever been. Dia-Compe use an evolution of SunTour's (minute of silence...) Power Ratchet system for nearly effortless shifts.
These are a special version for shifting 11-speed systems (and any lesser amount of speeds, of course). The right-hand shifter has an oversized barrel to pull more cable, making it possible to shift a derailer with a greater cable pull ratio over its full range.
Attach them to any frame with "Shimano-style" downtube bosses (including all modern frames with downtube bosses). These cannot be adapted to fit on thumb-shifter mounts or bar-end pods, as the oversized barrel would interfere with the mount.
- 11-Speed Compatible (Shimano, Campagnolo)
- Not great on SRAM 11-speed systems
- Downtube only?
- Yes, downtube only
- Not on my bar-ends or on a thumbie?
- Nope, downtube only
- How about weird transmission X?
- No clue, buy one and let us know how it goes.
