Mounting

These 'Type C' switches mount directly onto the brake master cylinder using the two original clamp screws and a new dedicated clamp. The clamp is supplied free with each switch, with the default clamp matching the bolt pattern of the standard bike, but you are free to choose an alternative clamp at the time of ordering at no extra cost.

We have brake clamps for:

• BR-A    32mm in-line bolts with a right offset switch location - Read
• BR-N    32mm in-line bolts with a left offset switch location for short brake levers - Read
• BR-B    30mm offset bolt spacing - Brembo XR , GP
• BR-F    30mm in-line as found on Accosato / Hel components
• BR-J     32mm offset bolts spacing as found on Beringer components
• BR-G    Generic clamp for any 21.8 > 22.2 mm handlebar (does not mount on the brake pump)

Unless otherwise specified we will supply the BR-A clamp for this application.

Clamps may be bought separately should you change this part at a future time, there is no need to replace the switch assembly

Perfect for saving space on the handlebar and ideally suited to bikes with aftermarket brake or clutch parts, or thumb brakes.
