Description
microSHIFT bar-end shifters are compatible with SHIMANO Road 12-speeds. They offer the simplest and most reliable shifting solution for drop-bar bikes. Adjustable shift tension and fewer moving parts mean they're less prone to breakage, easier to adjust, and offer flexibility in the unlikely event of a mechanical issue. Perfect for touring anywhere on the planet or for a ride with friends.
The shifter can be mounted on its own as a downtube shifter, or by using the thumb shifter mount it can be combined with a flat bar as a thumb shifter.
[FEATURE]
- High-precision machined aluminum
- Innovative torque bolt allows for adjustable shift effort
