Oh my… I started looking at dropper posts some time ago and gave up when the only offerings with 25mm setback were rubbish. Slop in the seat and wiggling about was unacceptable. I did dig up an old HiteRite spring from time been and gone and realize the damn thing was stupid light by comparison. Later I realized that I never was using it since I ride with 80-85% extension for the space needed to play and be trialsy.
One up is a good operation on many items they offer and quality has been good as well.
I have had a OneUp V2 dropper post on my bike for just over a year now and it has performed flawlessly. I have had no issues with it whatsoever. I also have their composite flat petals and they are really good too. I don’t think you can go wrong with any of their products.
