Description
The latest Rotor stem is now available in the UK.
The S2 Stem passed the most demanding European standard fatigue test (EFBe-Standard 7520), carried out by the German EFBe Institute, with very positive results. The S2 stem design easily passed the most stringent tests offered by this institute for both Road and MTB stems.
Obviously, laboratory tests do not always represent real life scenarios, so a number of top level athletes - pro and amateur, technically adept and dummies, alike - have been testing the S1 stem for over 4 months. The feedback received from these athletes, amongst which more than one UCI champion, was instrumental in achieving the S2 project's primary goal: To set a new standard.
The S2's DTT (Double Thread Technology) has certified itself as a bombproof clamping system for any application. This innovative bolt system already provides secure clamping of the handlebar with just 3,5Nm of fastening torque. It's easily capable of enduring the punishment that top level cycling can dish out.
All preliminary information valid as of today is as follows:
Only available in oversize clamp diameter (31.8mm)
Available with red or black face plate
Weight = 109g for 110mm stem
