Just taken my rockshox pikes apart and removed oil and wiper seals. Notice that in both lower legs at the bottom there is a circular rubber/plastic disc with a hole in the middle that the metal from the upper goes through, the questions i have are:
1. What is it?
2. What does it do?
3. Why is one of mine straight and the other on slightly curved/bent?
Will it also need replacing?
bottom out bumpers.
thread them back onto the prongy bits at the bottom of the stanchions before you re-install them.
Why was one of them slightly bent?
Might have happened coming out. Nothing to worry about. I personally prefer to poke them back into the lowers, checking they're flat against the bottom before installing stanchions.
I think they also enable tightening of the damper rod bolt. The one time I forgot to put them back in, I couldn't tighten the bolt under the rebound knob because the damper rod was just spinning round with it.
My worry was that they had been running with one not properly inserted althugh dont think this is the case.
