The crown race should have an inside diameter of 30.0mm (1 1/8“ Standard). The crown race should be slightly smaller than the crown race seat so that a press-fit is required to set the race firmly onto the fork. Measurement - Dim B 2. Make sure that the lower triple clamp is sitting flush with the lip on the bottom of the steerer tube. If it is not, loosen the steerer clamp bolt and slide the steerer up until the bottom lip on the steerer is against the bottom side of the lower triple clamp. Retorque the steerer clamp bolt to 85 in-lbs. 3. Slide the crown race onto the steerer tube and install the race using a slide hammer or other race installation tool. 4. Inspect the race and make sure that the bottom of the race sits flush with the crown race seat on the lower triple clamp and that the race is firmly in place. Proper Steerer Tube Step #4 - Install the fork. Installation 1. Slide the steerer tube into the headtube of the bike and, while supporting the bottom of the steerer tube and lower triple clamp with your hand, slide the upper cup or race of the headset onto the steerer. 2. Route both derailleur and rear brake cables between the two triple clamps and in between stanchion tube and head tube. CAUTION: DO NOT route cables outside of fork legs. Loss of control and serious injury may result. Always! route cables between fork leg and head tube. Crown Race Installation 3. Slide the upper triple clamp onto the steerer tube and the stanchion tubes and temporarily tighten the steerer cinch bolt. Important! Do not cut the steerer tube at this point. Install steerer and fork Proper Cable Routing Step #5 - Decide where you want the upper triple clamp mounted. The position of the upper triple clamp on the Chubby forks is somewhat flexible. You can place the upper triple clamp directly on top of the headset, or you can space it up so that it clamps up higher on the stanchions. Remember: the position of the lower triple clamp is FIXED, and should not be moved up or down. The steps below will show you how to mount the upper triple clamp properly in any location. 1. With the upper triple clamp temporarily installed, slide the stem (with handlebar attached) onto the steerer and position it where you would like it. Tighten the stem cinch bolts and sit on the bike to check the handlebar height. Do not ride the bike like this. You are only checking handlebar position now. Note: If you want a lower stem position, the stanchion tubes will probably extend above the top of the upper triple clamp. Make sure this is what you want before making any alterations to the steerer tube. 2. If you would prefer to have the top of the stanchion tubes flush with the top of the upper triple clamp, you will need to place enough headset spacers on top of the headset in order to do so. Measure the amount of exposed stanchion tube with the upper triple clamp installed directly on top of the headset. This is the amount of headset spacers you Option 1 will need. 3. Install the headset spacers and upper triple clamp into the desired position and tighten steerer clamp bolt to 85 in-lbs. 4. Insert the two spring stacks and preload adjusters into the stanchion tubes and tighten with the Chubby Wrench. 5. Tighten the remaining bolts on the upper clamp to 85in-lbs. 6. Rotate the fork and check for any binding or grinding in the headset. If the fork rotates smoothly, continue on to the next step. If the fork binds or the headset feels rough, loosen the upper triple clamp and repeat step 3. Step #6 - Install the star-fangled nut, stem, handlebar and brakes. That's it! 1. If you will want to cut the steerer tube, make sure that you have enough room for your stem. DO NOT cut the steerer tube too short! Also, make sure the star-fangled nut is properly placed in the steerer tube before you do any cutting. Option 2 2. Install the star-fangled nut into top of steerer tube 10 - 12mm from the upper surface with star fangled nut installation tool, if it is not installed already. Do not attempt to install the star-fangled nut without the proper tool. 3. When installing your stem, the distance between the top edge of the stem clamp must extend above the top of the 10-12mm steerer tube 1-3mm. If the distance is incorrect, remove the stem and add or remove spacers on top of the upper triple clamp to achieve a 1-3mm distance. CAUTION: Assembly with the top of the stem extending more than 3mm above the top of the top of the ! steerer tube can result in fork failure during use and severe injury. Proper Star-Fangled Nut Installation 4. Insert the Aheadset cap and screw through the top of the stem and into the star-fangled nut. Use the threadless headset cap to adjust the headset as per the manufacturer's instructions. Remember: You will need to loosen all of the upper triple clamp bolts and the stem clamp bolts to adjust the headset. 1-3mm 5. Tighten the two stem bolts to 90-120 in-lbs or refer to the stem manufacturer's torque specs for the stem. Install the handlebar...
