Polygon Bend R9X Review

Dec 2023

The aluminum-framed Polygon Bend R9X gravel bike, with premium components, offers a distinctive alternative in the carbon-dominated gravel bike market, though its unique features may not suit everyone based on testing.

Highs
  • Carbon wheels and SRAM Rival AXS drivetrain are the highlight of a pretty solid spec for the price

  • Aggressive geometry capable of pushing the limits of “traditional” gravel riding

  • Generous mounting options on frame and fork

Lows
  • Aluminum frame felt harsh on washboard roads and pocked trails

  • RockShox Reverb AXS post was too short for low-slung frame

Polygon Bend mounts an affordable alloy gravel adventure bike

Oct 2023 · Tyler Benedict

With tons of mounts, a carbon fork, compliant rear end, and slack front end with huge tire clearance, what's not to like?
