Dial in your riding position with the PRO LT Stem, a tough anodised alloy stem whose reversible angle lets you switch between an aggressive, aerodynamic stance and a more upright, comfortable one. The four-bolt Headlock faceplate clamps your bar securely and evenly, so you can ride with confidence on road, gravel or trail.

Highlights

  • Reversible ±0°, ±6°, ±17° and ±35° angle lets you raise or drop your front end without buying a new stem
  • Four-bolt Headlock faceplate spreads clamping force evenly for a secure, bar-friendly hold
  • Anodised 6061 alloy construction balances strength, stiffness and value
  • 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm and 120mm length and 31.8mm bar clamp suit a wide range of road and off-road setups
  • Clean black anodised finish that works with almost any frame

Reversible angle, two positions

Run the stem angled up for a relaxed, endurance-friendly position, or flip it to the −0°, ±6°, ±17° and ±35° orientation for a lower, racier front end. One stem covers two very different fits, so you can fine-tune your setup as your flexibility, goals or bike change.

Headlock faceplate

The four-bolt Headlock front clamp distributes pressure evenly across the handlebar, helping keep the bar held firmly in place and reducing the risk of uneven loading on your bars.

Built to last

Machined from anodised 6061 aluminium, the LT Stem is a dependable, hard-wearing choice for daily riding and varied conditions.
