Equipped with new special GRD5 Titanium Torx bolts.

Why 25.4mm standard beats 31.8mm?

Front clamp has been totally redesigned and heat treated to minimize consequences of incorrect bolt tightening.

Design and dimensioning are impressive, mass and stress concentrations have been farther reduced.


Now it's lighter and even more resistant to abuses. Our new military standard alloy treatments doubles fatigue strength.


New multiaxial machining allows material shaving where only few years ago was impossible.

When you'll see it in flesh you'll realize it's an absolute performance sculpture.

Beware! You can find RoadStem copies!
None of them will even get close to original RoadStem stiffness and performance.
