Paul Components Shimano Thumbies (MTB) – Pair – Black

Miss thumb shifters? Converting a drop bar bike to flat bars? The Paul Components Shimano Thumbies (MTB pair/black) easily transform bar end (aka barcon or TT) shifters into thumb shifters.

The shifters are not included, but are readily available in 8 through 11-speed versions, and many have an option for friction-shifting.

Thumbies bring back the thumb shifting of old, and Paul think it makes shifting more precise and smoother.

Thumbies have a hinged clamp for an easy installation and fit handlebars with a diameter of 22.2mm. The clamp is raised up to give clearance for hydraulic brake levers.

Paul Components currently make Thumbies to work with Shimano shifters only. It has a shifter mounting boss that fits Shimano bar end shifter and some Shimano downtube shifters.
