New Ultimate Evo Stem Details
The New Ultimate Evo Stem showcases their optimal stiffness construction (OSC) – a lightweight, stiff and CEN-approved construction method. OSC is an innovative concept design to distribute stress evenly at the handlebar and stem interface. According to New Ultimate this reduces weight without reducing rigidity.
OSC consists of three different parts, winglets on the faceplate, variable radius machining and a innovative faceplate clamping mechanism. The winglet shape of the faceplates is designed to distribute the stress of clamping forces. The two piece design also increases force distribution while reducing weight. The faceplates feature a unique locking interface that securely clamps the bars and helps decrease flex that could be introduced through the bolts. Finally use of variable radius machining in the shaft of the stem resists flex by using thicker walls where needed, while keeping weight down by using thinner walls where forces aren't as high.
The New Ultimate Evo stem has a maximum rider weight of 90 kg (198 lbs).
The New Ultimate Evo stem has a unique clamping mechanism for the handlebar. First remove the face plates and look at the inside face. You'll notice one side is flat while the other side has a waved shape to it. The waved side should always be installed on the top and tightened so there is no gap. Finally tighten the lower bolts to spec. The bar clamp interface may not require any carbon prep compound, due to the texture on the faceplate. If you do feel like an extra amount of security against slippage, a small amount could be applied to the opposite side of the clamp.
