JackRabbit Rear Brake Caliper – XG, XG Pro & OG2 Pro

OEM replacement rear brake caliper for the JackRabbit XG, XG Pro, and OG2 Pro. This is the stock cable-actuated mechanical disc caliper. Replace it if the caliper body is damaged, the actuator arm sticks or won't return, or the brake can no longer be adjusted to stop reliably.

Compatible with – rear brake:

• JackRabbit OG2 Pro
• JackRabbit XG
• JackRabbit XG Pro (1.0 and 1.1)

Rear caliper only. Not listed as compatible with the original OG, OG2, or MG series. XG owners replacing the front brake need the Front Brake Caliper – XG.

Upgrade option for OG2 Pro riders: the Hybrid Hydraulic Brake Caliper also fits the OG2 Pro rear and uses your existing cable. It does not fit the rear of the XG or XG Pro, so this mechanical caliper is the rear replacement for those bikes.

Installation: Brakes are safety-critical, and caliper swaps need correct alignment to the rotor and cable tension adjustment. JackRabbit recommends professional installation, and our service team can install and dial it in at our NYC showroom.
