Microshift 10-SPEED MTN Thumb Shifters Micro Shift Flat Bar Shifters are just what the minimalist ordered! These low-profile thumb shifters are perfect for everything from your retro-inspired townie build to a bikepacking rig built to withstand the apocalypse. Simple operation and a classy, straightforward aesthetic are matched with efficient performance and the versatility of switching between friction or indexed shifting (for the rear shifter). The front shifter operates in a micro friction mode that works with both double and triple cranks. The rear shifter is dealer's choice. Run it in friction for that classic feel or switch it into indexed for a precise modern shifting experience. Though these shifters are designed to work with modern 10 speed indexed drivetrains, setting them up in the friction only mode allows you to pair them up with 5-8 speed drivetrains as well.
