Review: Transition Spur V2

Mar 2026 · Cole Gregg

This Transition Spur V2 finds it a more confident and capable short-travel trail bike without losing an ounce of the pep. See how it rides.

Highs
  • Efficient climbing and eager to gain speed

  • Confident and composed descending for a short-travel bike

  • Poppy, playful, and balanced for flow trails and jump lines

  • Excellent seatpost insertion allows 250mm dropper

  • Rattle-free fully internal cable routing

  • Boom Box storage is convenient and secure

  • Slick hidden hardware for a polished look

  • Frame weight increase only 0.2 lbs

  • Multiple build options and frameset available

  • Lifetime warranty on frame

Lows
  • Not the plushest short-travel bike

  • Limited side knobs on Maxxis Forekaster tires require learning when pushing hard in corners

  • Forward riding position puts pressure through hands on flatter climbs (remedy with taller bar)

  • Doesn't deliver tons of traction on loose, ultra-steep grinds

  • Shimano XT Di2 makes noise on big hits from derailleur snapping back

Review: The New Transition Spur is Lightly Revised and Still Just as Fun

Mar 2026 · Mike Kazimer

In-frame storage, adjustable geometry, and a shorter seat tube are a few of the key updates.

Highs
  • Hits the mark when it comes to overall handling.

  • Short stems, higher rise bars, and longer dropper posts are great to see on a 120mm bike.

Lows
  • The frame weight's reasonable, but gram counters may want something even lighter.

  • Even the base model is on the pricier side of things.

LONG TERM REVIEW: TRANSITION SPUR - MINIMIZED EFFORT FOR MAXIMUM TRAIL EXPERIENCE - Mountain Bike Action Magazine

Dec 2024 · Ron Koch

Transition’s lightness, both in feel and on the scales, makes for a bike that can be pedaled farther and pointed down gnarly lines with fresh legs, thanks to the overall efficiency.
