Staff Rides: Mike Kazimer's Transition Spur

Nov 2021 · Mike Kazimer

Call it a downcountry bike, a short-travel trail bike, or an aggressive XC bike, at the end of the day this Spur is all about having a good time, no matter which way the trail points..

Transition Spur X01 review

Jul 2021 · Robin Weaver

The Spur manages to balance speed and efficiency with more than enough downhill composure that would put a lot of longer travel trail bikes to shame

Highs
  • Great geometry

  • Smooth and composed downhill

  • Sprightly and efficient uphill

  • Reactive and fun to ride

Lows
  • Needs a 180mm rear rotor as standard

The Beta Tests: Transition Spur X01

Feb 2021 · Nicole Formosa

With how perfectly the Transition Spur walks the line between XC and trail, you'd never know it was the brand's first go at it.

Highs
  • A true modern trail bike

  • Super efficient climber

  • Parts spec skewed for descending

  • Lightweight (5.4 pound frame, 25.2 reported test weight)

  • Lifetime warranty

Lows
  • Entry-level price for a complete bike is $5,000

  • May not be XC enough for die-hard racers

Transition Spur: first ride review - MBR

Jul 2020 · Danny Milner

Transition Spur joins the downcountry mountain bike wave. Sporting modest amounts of suspension travel but not shying away from aggressive geometry.

Highs
  • A bike that constantly tugs at the reins, and your heart strings. Minimal mass, maximum fun. Great sizing and geo.

Lows
  • Frame flex is noticeable but can be toned down. Lack of front hub Torque Caps is an oversight. Seat post either slips or sticks. BB a touch high.

Transition Introduces the Spur

Jun 2020

The latest in a new wave of aggressive cross-country bikes is the Transition Spur. Equal parts going big and going fast, the Spur doesn't appear to like compromise.

Don't let the 120mm number fool you. The new Transition Spur is here to party - after pedaling up the entire mountain beforehand, of course.
