OneUp Components Dropper Post V2 Rebuild Kit

Easy to fit and at a fair price. Revives a sticky post

Haven't used these yet, as they are spare for when I do, as they aren't always available. The OneUp posts are popular for good reason and I can only assume this product is the same good quality. I'm 2 years in on the posts and still don't need replacement seal. I'd also buy a spare air cartridge if you want to ensure reliability and you don't have a spare bike – you won't know how much you'll miss your post until it suddenly doesn't work.

Haven't put to use yet, but like having spares on hand especially in these times when stock can be hard to come by but will say that price is very reasonable for what you get, nothing worse than crazy expensive bits to service/repair things.
