Sharpen your front-end control with the PRO LT Stem, a short and stiff alloy stem that quickens steering response for technical trail riding. At just 40mm long with a 0-degree rise, it pulls your bars in close for a confident, in-control cockpit on tight, twisting singletrack.

Highlights

  • Short 40mm length for fast, direct steering on technical terrain
  • Stiff 6061 alloy build that holds your bars planted under hard riding
  • 0-degree rise keeps your cockpit position neutral and predictable
  • Fits standard 31.8mm handlebars and 1 1/8" threadless steerers
  • Clean black anodised finish that suits any modern MTB build

Built for trail control

A shorter stem brings the handlebars closer to the rider, making the steering feel more immediate and lively. That extra responsiveness is exactly what you want when threading through tight corners, rock gardens and technical climbs, where small steering inputs need to translate straight to the front wheel.

Stiff alloy construction

The LT Stem is forged from 6061 aluminium for a strong, rigid platform that resists flex when you load up the front end. The result is a precise, planted feel through the bars and reliable everyday durability.

Compatibility & fit

The LT Stem clamps a standard 31.8mm handlebar and mounts to a 1 1/8" (28.6mm) threadless steerer tube, the most common Ahead setup on mountain and gravel bikes. Confirm your bar clamp area is 31.8mm and your fork uses a 1 1/8" steerer before fitting. It is part of the LT family, which also offers 50mm and 60mm lengths if you prefer a slightly longer reach.
