The Race Face Chester 31.8 Stem (50mm, 8° Rise, Black) is a highly durable, budget-conscious component built for freeride, downhill, dirt jumping, and aggressive trail riding. Its design combines a 31.8mm handlebar clamp with a shorter 50mm length, offering quicker and snappier steering response compared to the longer 70mm variant.

  Features a 4-bolt handlebar clamp configuration engineered to shift the physical load directly into the stem body, reducing structural stress on the faceplate bolts.
• Handlebar Protection:
  Designed with smoothed internal faceplate transitions to eliminate sharp edges, minimizing the risk of material fatigue or score marks on alloy and carbon handlebars.
• Crash-Inclusive Warranty:
  Built with raw material strength in mind rather than ultra-lightweight racing performance, the Chester stem is backed by the Race Face Lifetime Warranty, which officially covers crash damage.
