Details:

I bought a new fork with more travel that is why am selling this. For a 29 front tire. From a 2019 Epic Pro front fork only. I want some my money back from the rebuild.

This is a recently rebuilt RockShox SID Brain front fork. Nothing is wrong with it. This is perfect for XC bikes. 110mm boost spacing.
