How to realign the bottom steerer spacer on SL bikes

On non-integrated Ribble SL models, the bottom spacer in the headset stack can occasionally become misaligned. Here’s a quick and easy way to get it lined up again.

Step-by-Step Guide

1. Remove the top cap bung
   Pop out the rubber bung from the top cap bolt.

2. Loosen bolts
   Using a 4mm or 5mm Allen key, loosen the top cap bolt and the stem pinch bolts.

3. Reposition the spacer
   With the headset now loose, realign the bottom spacer so it sits correctly.

4. Check wheel alignment
   Make sure the front wheel is still in line with the stem and handlebars.

5. Tighten the headset bolt
   Gradually tighten until all play is removed from the headset.

6. Check for play
   Pull the front brake and rock the bike back and forth. If you feel movement, tighten the headset bolt a little more.

7. Check for resistance
   Turn the handlebars from lock to lock. If you feel resistance, loosen the headset bolt slightly.

8. Secure everything
   Once you’re happy with the headset tension, re-torque the stem pinch bolts and refit the top cap bung.
