Our review
Decent long-travel dropper option for those on a budget or with frame constraints, but not the smoothest – I’d opt for the V2 post instead

Pros:

Lots of (tunable) drop; super-low stack height; good value

Cons:

Lots of stiction in long-travel form; composite lever isn’t the most robust – get the alloy version instead

OneUp claims its droppers are the shortest available, both in total length and stack height – good news if your frame has an interrupted or tall seat tube, or you want to squeeze in a long drop.

My 170mm-travel sample measured 210mm from the saddle rails to the base of the collar, with another 243mm below that.

There are 150mm and 125mm options too, and a clever tool-free shim system lets you reduce travel by up to 50mm.

It’s easy to fit the post, with the cable being clamped at the lever end. The saddle clamp is a little fiddly, making it doubly important to check the return-spring pressure before attaching the seat.

After breaking the composite remote lever by overtightening it, I replaced it with the V2 alloy lever, which feels good and remains intact after months of use.

The post doesn’t have the smoothest action in 170mm form (even after I greased the upper bushing) and there was some rotational and fore-aft play from new, which I put down to the limited bushing overlap on this longest-travel version.

This hasn’t got any worse over time though, and OneUp appears aware of the issue because it's increased the overlap on the second-generation post – available now for $40 more – and specced a new DU bushing in the upper collar.

The V2 dropper comes in even longer-travel options and has a slightly shorter stack height, all of which makes it look like a better buy.
