Review: Marin Rift Zone Carbon 29

Nov 2022 · Dario DiGiulio

The Marin Rift Zone occupies a very unique spot in the bike market, as a short travel frame meant to attack relatively serious terrain.

Highs
  • Fun and unusual synthesis of parts and geo

  • Great build kit

  • Adaptable frame platform

Lows
  • Mix of progressive and dated geometry

  • Heavy and sticky for a short travel bike

Marin Rift Zone 29 1 review

Nov 2021 · Alex Evans

Highly-capable and upgradable chassis that inspires confidence on the descents

Highs
  • Highly capable on the downhills, thanks to spot-on geometry

  • Great suspension and shock tune with plenty of support and pop

  • Good mix of drivetrain components

Lows
  • Lack of a dropper post is frustrating

  • Tyres need upgrading to unlock more performance

  • In the longer term, I’d replace the flexy fork, too

Beta
Tested: Marin Rift Zone 2

Feb 2021 · Travis Engel

This short-travel shredder takes a modern trend and brings it to the entry level. The Marin Rift Zone 2 does (almost) everything.

Highs
  • Unbeatable value

  • Smart spec

  • Forgiving but familiar geometry

  • Supportive suspension

Lows
  • Oddly shaped brake levers

  • Shimano chain and crank would have been nice

Sep 2020 · Alan Muldoon

Geometry and sizing is consistent across the Marin Rift Zone range, so the fit is going to be identical, right down to the stubby 35mm stem.

Highs
  • Good angles and attitude

Lows
  • Spec at odds with travel
