Omega X Installation Guide
The Omega X installs much like a standard single-post brake, and is the easiest aero brake on the market to set up.
- Begin by removing the wheel - it is easier to install the Omega X without a wheel in place. We will bring it back for pad adjustment later.
- If your bike uses a direct-mount standard, either Shimano Direct-Mount or TRP U-Mount, begin by removing any pre-installed canti studs, to expose the direct mount bosses. These will be either M6 threaded holes (for Shimano Direct Mount) or M8 holes (for TRP U-Mount). The Omega X universal Direct-Mount Adapter is compatible with both. We include two versions of the Direct Mount Adapter, a High version usually best for front brakes, and a Low version usually best for rear brakes. Choose the version that will allow you to properly center the brake pads on your rim's brake track. When in doubt, use the High version for a front brake installation, and the Low version for a rear brake installation. They can be changed out later if needed. If your bike has both direct-mount AND traditional single-bolt attachment options (such as found on the Quintana Roo PRSix), always use the single-bolt attachment.
- Next, remove the Omega X Front Plate and install the brake with one of the included M6 Countersunk Thru Bolts.
Next, run brake cable housing up to the Omega X cable hanger, and run a brake cable through the brake levers on your handlebars, and through the Omega X Wedge. Pull the cable taut using a pair of pliers, and ensure there is no slack in the system by actuating the handlebar brake lever while also keeping tension on the cable. (If you are using an upstream cable stop, such as the integrated stop on the Sigma X, or Alpha X, you will of course run your housing to that stop and simply run bare cable through the Omega X Cable Hanger).
Keeping the cable taut with the pliers, tighten the M6 center pinch bolt on the Wedge, to a torque of 4 Nm.
Trim the cable, leaving approximately 1cm of cable below the Wedge. You may install a cable tip at this time if you wish. However, ensure that there is at least 3mm between the bottom of the cable tip and the bottom of the Omega X Back Plate arc, to ensure that the cable tip will not contact the Front Plate when it is replaced. Any cable interference will compromise the brake's ability to return properly.
Replace the Omega X Front Plate, and reinstall the wheel.
The Omega X comes with Kool Stop Salmon pads, the industry's best pad for use on alloy rims in any riding conditions. If you are using carbon rims, we recommend the SwissStop Black Prince pad, available at your local bike shop. Adjust the pad height and pad angle, ensuring it properly contacts the center of your rim's brake track. Using the M4 set screws on the sides of the Omega X Levers, adjust the pad stance width so that the pads are 1-2mm away from the rim on either side. (If you used a Direct Mount Adapter and cannot adjust the pads to sit in the center of your rim's brake track, switch to the other adapter size).
You're ready to ride!
- If your bike has a standard single-post brake mount, thread the M6 Thru-Bolt through the brake, then through Serrated Washers positioned on the back of the brake. Pinch in place and slide the whole onto the fork. Hold it in place with a 4mm hex wrench, while you tighten the Recessed Nut with a 5mm wrench. Tighten to a torque of 10-15 Nm, or whatever is recommended by your fork manufacturer.
- If you are using the Direct-Mount Adapter, choose the shortest bolt, which is 14mm long - you do not need any additional Serrated Washers or Recessed Nut, as they are integrated into the Direct Mount Adapter itself. Tighten using a 4mm hex wrench to a torque of 7-8 Nm.
