MOOTS YBB REPLACEMENT SPRING
The Moots YBB Replacement spring can be used to adjust the firmness of your YBB unit. Also, when it's time to rebuild your YBB units, it's a good measure to replace the spring at the same time. YBB Rebuild Kit is sold separately.
You will need to remove your current YBB build and measure the spring for sizing.
This is a NON-REFUNDABLE item.
