JackRabbit Hybrid Hydraulic Brake Caliper – OG Rear / XG Front

The premium hybrid hydraulic caliper JackRabbit specs on its top-line bikes, now available as an upgrade for the OG, OG2, and XG families. It's a direct replacement for the stock mechanical caliper that gives you stronger, smoother, more consistent braking.

How hybrid hydraulic works: Your existing brake cable actuates a sealed hydraulic piston at the caliper. You get the braking power, modulation, and wet-weather consistency of a hydraulic system, and the pistons self-adjust as pads wear. There are no levers to swap and no hydraulic lines to bleed.

Compatible with – check your brake position:

This caliper does not fit the rear brake on the XG or XG Pro. For those bikes, the rear replacement is the Rear Brake Caliper – XG, XG Pro & OG2 Pro.

Installation: Brakes are a safety-critical system, and JackRabbit recommends professional installation for caliper swaps. Our service team can install and adjust it in-house at our NYC showroom so it's dialed in before you ride.
