Roox S4.2 MTB seatpost – Various sizes


Mid 90s lightweight inline MTB seatpost in a range of sizes



The Roox S4 seatpost was a fairly underground upgrade back in the day, not often seen in the UK but similar in design to the legendary Syncros post. The inline design with simple cradle and top clamp was used by a few brands including USE, and its a a simple and easy to adjust system. Roox made some really trick bits including a great crank set and some neat stems, I always thought of them as a European Race Face!

These posts are pretty long at 420 mm from the bottom to the rails and this 2nd generation model has a silver stripe running up the back as pictured. We also have some of the all black first generation S4.
