The NDC chain adjuster is a great upgrade from the stock Grom adjusters. The NDC chain adjuster allows you to mount swing arm spools so you can use a stand for tire changes. Tire changes with our adjuster is much easier then before due to the fact the adjuster will stay in position and not fall out when trying to install the wheel/axle. Our chain adjusters use a 8x1.25mm bolt for the spool. When ordering quantity of 1 they come as a set.
**2022-2024 chain adjustment will be limited due to length of adjuster block.**
