By reversing the grip challenge for normal brake levers, the thumb brake allows you to easily push the lever with your thumb instead of gripping with your fingers. Post mount it beside an SB – or normal brake lever to provide one-hand brake control for both rear and front brake. The Thumb Brakeprovides easy and soft activation of both active brake and parking, with less than 10% of normal hand force.
• Active brake by pushing the lever/trigger. The braking force follows the lever movement.
• Parking brake is activated by triggering the lever four times in a row within 5 seconds. To deactivate the parking brake, squeeze the lever once.
