The $1100 (USD) Marin San Quentin 1 Hardtail

Sep 2022

The complete Marin San Quentin 1 (SQ1) hardtail costs about the same amount of money as a top-end RockShox suspension fork and it's a fun choice for the aspiring or casual mountain biker looking for a budget-friendlier gateway rig for Blue-level trails.

Oct 2019 · Tom Marvin

Compromised spec, but the descent-focused geometry starts to shine on steeper terrain

Highs
  • Aggressive geometry makes it a confident descender

  • Wide rims give tyres good volume and shape

Lows
  • High weight and limited gear range compromise climbing potential

  • Spec choice
