You want the linear, controllable feel of hydraulic brakes. You do not want to throw away a mechanical groupset that costs more than the bike did and still works perfectly. Until now that was the choice.

The F1 removes it. Your existing brake cable pulls a lever inside the caliper, and that lever drives two hydraulic pistons. Mechanical in, hydraulic out. No new levers, no re-routing, no bleeding. We did not chase a violent initial bite; we tuned the F1 for the most stable, predictable braking control you can hold at the lever.

The F1 uses the Flat Mount standard that modern road and gravel frames are built around, and its body is designed directly for a 160 mm rotor. Bolt it to the frame or fork and it lines up. No adapter plate, no extra bolts, no stacked tolerances.

Cleaner looks, less weight, and a stiffer connection between caliper and frame exactly where braking loads are highest.

Fully sealed hydraulic systems self-adjust, but they do not let you choose. The F1 gives you a knob. As pads wear and the gap grows, turn it by hand, no tool, and the clearance is back. Dial it slightly further and you have chosen your own bite point.

Consistent lever feel from the first ride to the last millimetre of pad.

The caliper body starts as a European high-purity 6061 aluminium billet, die-forged so the grain follows the load path, then CNC-machined to its final piston bores and internal oil passages. The pistons are 7075 aluminium for strength and heat dissipation on long descents.

100% designed and manufactured in Taiwan. Automotive and motorcycle design philosophy, brought to the bicycle. UNLEASH! NEXT LEVEL.

The F1 works with any standard short-pull (C-brake) lever. For the most direct feel, pair it with the JuinTECH C1 brake lever, whose pull ratio is calculated for our Hybrid Hydraulic calipers and removes vague travel before the pistons move.

Match it with RT01Z rotors and the whole braking system is tuned as one. Tip: fresh, low-friction inner and outer cables make a bigger difference than most riders expect.
