Thumbies bring back the thumb shifting of old, and we think it makes shifting more precise and smoother. These feel much better in our opinion than trigger or twist shifters.
Thumbies have a hinged clamp for an easy installation and fit handlebars with a diameter of 22.2mm or 31.8mm. 22.2mm is equivalent to 7/8 inches, and is the diameter of most mountain bike handlebars. Many flat bars, risers and city bars have this diameter. It is measured at the end of the bar where grips and brake levers attach. 31.8mm is most commonly used on modern road handlebars near where the stem clamps.
The clamp is raised up to give clearance for hydraulic brake levers.
They have a shifter mounting boss that fits Microshift and Gevenalle mountain shifters.
