We are proud to introduce our latest product offering – Full CNC Machined Master Cylinders.
We manufacture all metal parts of the master cylinder (including levers) in-house on our suite of Brother and Star CNC machines from solid billets of 6082-T6 aluminium.
Each master cylinder body takes an hour of machining time to remove the material to our exacting standards with the bore measured automatically in cycle.
Each master cylinder is individually finished and assembled by hand and comes with our latest design of lever which allows three ratios from one lever.
The lever features a pill shaped hole into which one of two plugs are inserted, One has an offset hole – with the hole nearest the master cylinder you get a -1 ratio. If you rotate the plug 180 degrees it offers you a +1 ratio and if you use the plug with a central hole you obtain a 1:1 ratio. This means that with a 16mm master cylinder you can obtain a 15/16, 16/16 and 17/16 from one lever and two inserts.
With the 19mm master cyilinder you can obtain an 18/19, 19/19 and a 20/19 from one lever and two inserts.
16 – Clutch master cylinders or single front brake (smaller CC models)
18 – More lever travel and 'feel' on twin caliper systems (larger CC models)
19 – Average lever travel but harder feel – a good all rounder
20 – Less lever travel and the 'hardest feel' on the lever
HEL Performance Master Cylinders include a fully cnc black lever offering three ratios in one.
All parts for our master cylinders are available to purchase separately and we will be adding this option on this page in the future.
