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, including 65-degree head tube angle and long reach

  • Excellent climbing efficiency for a hardtail

  • Good momentum and steady speed once spun up

  • Steel frame provides subtle flex and comfort

  • DT Swiss wheels remain true and stiff despite hard hits

  • Fox 36 fork with adjustable FIT damper performs well

  • Shimano XTR brakes powerful and consistent

  • Shimano XTR drivetrain shifts perfectly

  • Race Face Turbine Dropper post works flawlessly in cold weather

  • Chromag saddle comfortable for hardtail use

Lows
  • Technical climbs require A-game and are not the Primer's strength

  • Tires (WTB Bridger 3.0) have only so-so rock face grip and less aggressive side knobs

  • Cornering not particularly nimble for side-to-side transitions

  • Acceleration is not violent due to weight and wheel inertia

  • Brakes squeal in cold weather until warm up
