If you need the rear 140mm, just remove the rear seat, like this Wire Pull Oil Disc Calipers for Road Bikes, Gravel Bikes Direct mount hydraulic brakes Brand: ONIRII Model: BR-05 Material: aluminum alloy Process: CNC Brake pad: same as Shimano XT brake pads Brake pad: length 32.3mm width 16.4mm Color: black, titanium, silver, red, purple, pink, gold, blue Surface: glossy Suitable for: road bike/gravel bike Brake weight: without supporter 160g, with supporter 176g Full set weight: with floating rotor 533g , with ultra-light rotor 570g Mounting hole distance: front brake 72mm, rear brake 34mm Brake oil: mineral oil The brake wire pulling method is changed to the inside, which not only solves the problem of wire cornering, but also improves the feel and braking power Through many improvements and tests, our BR-05 has fully realized the bilateral braking effect Why choose a dual piston brake? General brake single piston work leads to easy rotor deformation, uneven left and right friction, and limited brake braking power BR-05 Dual piston work Rotor always keeps central position, not easy to deform, smooth friction between left and right side, high braking force Brake pad installation and selection Our brake pads are the same as Shimano XT Front brake supporter front mounting 160mm, reverse mounting 140mm ①Brake wire fixing screw ②Wire adjustment screw ③Oil filling screw ④Stroke trimmer screw ⑤Oil filling screw ⑥Brake pad bolt ⑦Made by CNC process Practical oiling method Adopting front-to-back oiling method, this oiling method can effectively evacuate the air inside the brake You can do the oil change and brake maintenance by yourself through the brake oil fill hole Application of brake supporters Front brake: 140mm and 160mm universal Rear brake plus this supporter is 160mm Frame hole spacing mounting specifications Proof of professional testing Our brakes have a TUV test certificate, the TUV mark is a safety certification mark customized for component products by TUV Germany and is widely accepted in Germany and Europe.
