Qnium Radial Rear Thumb Brake Master Cylinder 12mm
The Radial Thumb Brake from Qnium is one of the most optimized thumb brakes on the market for the rear wheel. As a rider you have a lot more feeling in your thumb than in your foot. The Qnium Radial Thumb Brake makes it easier to operate the rear brake in a very controlled way. This high-end thumb brake is very popular in the Moto3 class. A brake lever is not an option on these bikes, as Moto3 riders are required to use the clutch lever. When you mount the Rear Master from Qnium on your bike, you can continue to use your foot brake.
Used in Moto2, Moto3, and in other FIM world championships. Drivers like Tony Arbolino and Dennis Foggia managed to win Grand Prix races with the revolutionary Qnium Thumb Brake. In 2019 Lorenzo Dalla Porta also used the Qnium’s Radial Thumb Brake, when he became World Champion Moto3.
Made in The Netherlands
Many riders like to control the rear brake with their left hand. In your fingers you have a lot more feeling than in your foot. In that case you can opt for the Qnium Radial Thumb Brake.
This radial thumb brake is optimized at all points to get the brake feeling to the highest possible level. The pivot point and the pivot point of the trade adjustment are both double bearings, which means that the friction around 25 bar pressure in both pivot points are eliminated. This results in less force with the thumb to get the same brake pressure.
More importantly, the feeling improves so that the rear brake is easier to control.
Mark was exactly right, the quality of this product is remarkable. Exactly as promised!!!

Looks like incredible engineered products, both the thumb brake & the rear master cylinder. On the master cylinder, be aware QNIUM use 6mm bolts where as the stock Triumph 675 bolts are 8mm. Not a big deal, just be aware.
