S1 50mm MTB Stem, 31.8mm, Forged

S1 MTB Stem

Forged 6061 aluminium for high strength and fatigue resistance at a reasonable weight. A four-bolt bar clamp holds the bar securely. The interlocking U-shaped clamp puts more of the load through the stem body, not the bolts, and the faceplate avoids the stress risers that can make a bar bend or break.

Will it fit my bike?

• Steerer: 1 1/8 inch, the standard on mountain bike forks, including tapered forks (1 1/8 inch at the top).
