Why We Like The OneUp V3 Dropper Post

The best just got better with the OneUp V3 Dropper Post. Improving upon their award-winning V2 dropper post, OneUp made the V3 lighter by 60 grams, available in more sizes so long-legged riders have a suitable option, and a smoother operation by adding improved seals, bushings, and a new cartridge. The enhanced design means more time between maintenance, less effort to drop the saddle, and a more durable design. The V3 still has the same travel adjustment features we love from the V2 and gives us the ability to shorten the extension length by up to 20mm through the use of the included travel adjustment shims so we can get the perfect fit. The V3 is improved in every way over the V2 and is a great option for riders of all experience levels and riding styles.
