Reverse Angle Spacer Fine-Tune Your Fork With the tapered Angle-Spacer forks (crown race), you can fine-tune and modernize the geometry of your bike. This simple spacer allows you to make the steering angle half a degree (- 0. 5deg) slacker, enabling you to get even more performance out of the bike on steep and gnarly descents. The spacer replaces the conventional crown race and is mounted between the fork crown and the headset. The Angle-Spacer can be used with any headset with 45deg ball bearings. To use the Angle Spacer, simply take the fork out of the frame and then remove the existing crown race from the fork crown. The Angle-Spacer is mounted directly above the fork crown where the old fork Crown Race was previously located.
