It is extremely important that your RockShox fork is installed correctly by a qualified bicycle mechanic. Improperly installed forks are extremely dangerous and can result in severe and/or fatal injuries.

1.Remove the existing fork from the bicycle and the crown race from the fork. Measure the length of the fork steerer tube against the length of the RockShox steerer tube. The RockShox steerer tube may need cutting to the proper length. Make sure there is sufficient length to clamp the stem (refer to the stem manufacturer's instructions).

!W A R N I N G

DO NOT ADD THREADS TO ROCKSHOX THREADLESS STEERERS. THE STEERER TUBE CROWN ASSEMBLY IS A ONE-TIME PRESS FIT. REPLACEMENT OF THE ASSEMBLY MUST BE DONE TO CHANGE THE LENGTH, DIAMETER OR HEADSET TYPE (THREADED OR THREADLESS).

DO NOT REMOVE OR REPLACE THE STEERER TUBE. THIS COULD RESULT IN THE LOSS OF CONTROL OF THE BICYCLE WITH POSSIBLE SERIOUS AND/OR FATAL INJURIES.

2.Install the headset crown race (29.9mm for 1 1/8" steerers) firmly against the top of the fork crown. Install the fork assembly on the bike. Adjust the headset until you feel no play or drag.

3.Install the brakes according to the manufacturer's instructions and adjust brake pads properly. Use the fork only with V-type or hydraulic cantilever brakes mounted to the existing brake posts or disc style brakes mounted through the provided mounting holes. Do not use any cantilever brake other than those intended by the brake manufacturer to work with a hangerless brace.

4.Adjust the front wheel quick release to clear the dropout's counter bore. The quick release nut must be tightened after the wheel is properly seated into the dropout's counter bore. Make sure four or more threads are engaged in the quick release nut when it is closed. Orient the quick release lever in front of and parallel to the lower tube in the locked position.

5.Keep in mind tire clearance as you choose tires. Maximum size is 2.4" wide or 348 mm radius installed. Be sure to check this radius whenever you change tires. To do this, remove the top caps and spring stack assemblies and compress the fork completely to make sure at least 5 mm of clearance exists between the top of the tire and the bottom of the crown. Exceeding maximum tire size will cause the tire to jam against the crown when the fork is fully compressed.

RockShox Judy forks can be tuned for your particular weight, riding style, and terrain.

Setting Sag

Judy forks are designed to sag when you are sitting on your bike. Sag is the compression of the fork caused by the rider's weight. Proper sag allows the front wheel to follow the contour of the terrain as you ride. Sag is adjusted by the amount of air you add to the fork (less air equals more sag).

To measure sag, install a zip tie on the upper tube of the fork flush against the wiper seal. Sit on the bike with normal riding apparel. Step off the bike, and measure the distance between the wiper seal and the zip tie. This is your sag.

XC, SL specifications

JUDY CRAFT SL, XC is a groundbreaking suspension fork designed specifically for cross-country (XC) mountain biking, blending performance, precision, and lightweight construction. This innovative product caters to both competitive athletes and recreational riders who demand superior control and comfort on varied terrains.

One of the main features of the JUDY CRAFT SL, XC is its advanced air spring system. This system allows riders to easily customize their suspension to match their weight and riding style by adjusting the air pressure. This adjustability ensures optimal performance across different trails, enhancing both climbing ability and descending stability. The fork also includes a rebound adjustment feature, which allows riders to fine-tune how quickly the fork returns after compressing, adding to the overall ride quality.

The JUDY CRAFT SL, XC is constructed with lightweight materials that significantly reduce the overall weight of the bike without compromising strength or durability. The fork’s stanchions are crafted from high-grade aluminum, while the lower legs are designed for maximum stiffness. This combination of materials results in a responsive feel, providing improved tracking over rough terrain and increasing overall rider confidence.

In terms of technology, the JUDY CRAFT SL, XC integrates a unique damping system that optimizes performance during varied riding conditions. This system delivers an exceptional balance between plushness and support, allowing riders to maintain speed over bumps while retaining energy during climbs. Additionally, the fork features an easy-to-read measurement scale, making it simple for riders to adjust settings quickly and efficiently even mid-ride.

The overall geometry of the JUDY CRAFT SL, XC is another noteworthy characteristic. The fork is designed with a slacker head angle that enhances stability, providing better handling during steep descents. In contrast, the fork’s shorter axle-to-crown length supports nimbleness and responsiveness, crucial for tackling tight turns on race courses or technical trails.

With its mixture of lightweight construction, customizable settings, and advanced damping technology, the JUDY CRAFT SL, XC sets a new standard for cross-country suspension forks. It delivers a riding experience characterized by control, comfort, and efficiency, making it an excellent choice for riders looking to enhance their performance on the trails. Whether you are competing at a high level or enjoying a leisurely ride, this fork is designed to elevate every aspect of your mountain biking adventure.
