Chromag Primer 27+ Review

Feb 2017

Going back to a hardtail – even one with progressive geometry like the Primer – required patience. The payoff was well worth it.

Highs
  • Progressive geometry (65 HA, long reach, short stays)

  • Steel frame gives smooth, silky pedaling feel

  • Excellent climbing efficiency for a hardtail

  • Good momentum and speed maintenance

  • DT Swiss wheels stiff, durable, straight

  • Fox 36 fork well-tuned with good small bump compliance and progressivity

  • Shimano XTR brakes powerful and consistent

  • XTR drivetrain shifting perfect

  • Race Face Turbine dropper flawless in cold weather

  • Chromag saddle comfortable on steep climbs

  • Chromag OSX bars durable with nice flex

Lows
  • Not nimble in quick side-to-side transitions

  • Technical climbing requires attention and good line choice

  • Cornering requires aggressive inputs

  • WTB Bridger tire rock grip only so-so, rubber not stickiest

  • Knobs small, less aggressive than desired for some conditions

  • Wheel/tire combo heavy, acceleration not violent

  • Brake performance affected in cold (squeal), possible contamination
