Performance & Use Case
The Roval Alpinist Stem is a lightweight, rigid alloy stem built for climbing and sprinting. At 110g for the 110mm size, it gives a measurable weight advantage on uphill assaults and out-of-saddle efforts while retaining the stiffness needed for sprinting. The classic design and traditional 31.8mm clamp suit any race-oriented road bike.
Construction & Materials
3D-forged and CNC-machined 7075 aluminium with titanium bolts. The forging process gives the alloy higher fatigue strength than billet machining alone. Black anodised finish. Clamp height 40mm.
Compatibility & Variants
Steerer tube 1-1/8 inch; handlebar clamp diameter 31.8mm. Available in two rise angles (6° and 12°) across eight lengths (60, 70, 80, 90, 100, 110, 120, 130mm). The Specialized Alpinist 6° is the Specialized-branded equivalent (Specialized owns Roval) and is included under the same product family. Select the length and angle combination that matches your bike fit.
I was looking for a 100mm 6 degree stem which was as light weight as possible. Sigma had a very good and wide selection and a competitive price. It was easy to pick the one I wanted. Having made my choice, it was delivered quickly and free of charge! Well done Sigma!!
