Mason RAW Review: High-Caliber Hardtail

Aug 2023 · Miles Arbour

Find our long-term review of the Mason RAW after countless unloaded rides in the Pacific Northwest and bikepacking trips in Idaho and beyond

Highs
  • European/UK materials and fabrication using high-end Dedacciai and Reynolds tubing

  • Dialed geometry for trail riding, bikepacking, and multi-day epics

  • Smooth and efficient ride quality makes climbing, descending, and cornering a joy

  • High-end details, rack mounts, downtube mounts, and top tube mounts

  • Lots of frame bag space thanks to higher standover height

  • Lightweight frame and build kits are well-specced for long rides

Lows
  • Expensive, but justifiably so given local manufacturing, cost of materials, and overall quality

  • No sliding rear dropouts

  • Near-vertical seat stays might make it a little harsher than some other frames

  • No proper rear rack bosses at rear dropouts, although hidden removable ones work

  • Wouldn’t choose Hunt Proven carbon XC wheels for bikepacking
