OneUp Dropper V2 vs V2.1 - what's the difference?

V2 everywhere else is almost certainly the 2.1. difference was in the cable connection at the bottom and happened very soon after the post was launched many years ago.

Thought the 2.1 was a Santa Cruz mod due to their seat tube config, 2.0 is the mass market one, either way you can swap out if required at a later date as they sell it separately as well

2.1 became standard, there hasn't been a V2 for a while now. I think as above the 2.1 was brought in due to cable routing on some Santa Cruz bikes initially

0.1 I reckon.

Think new you can only get the 2.1 and the new v3, which incorporates the same actuator as the v2.1.

I have the v2.0, but it's about 3 years old, and went through the 'is v2.1 newer', only to find out it was the same, but different due to santa cruz and their bloody weird suspension design 😂

I'd thank Santa Cruz for that. If I remember correctly the V2 actuator worked by fixing the inner cable and moving the outer which was always a bit iffy but especially problematic on certain bikes. V2.1 fixed the outer and moved the inner in a far more conventional manner and we all benefited as a result.

Anyone using a v3 in anger yet? Seen them fitted to bikes (new), but was wondering if anyone was out there putting the miles in on one yet?

It reads well ... https://www.pinkbike.com/news/oneup-announces-new-v3-dropper-post-2024.html

I haven't got one, but interesting to read at the end of the article that they're providing better components for the V2, too.

New upgrades available for V2:
- New V2.1 Collar with SKF Seal upgrade for V2 droppers coming soon
- Ti Bolt upgrade kit is compatible with V2 and is available now for $14.99 USD
- All V2 replacement parts will be available for at least another 5 years

OneUp has supported me really well with my V2, even sending me parts that aren't available for sale separately.
