Summary

The Transition Spire is a robust and predictable enduro bike, praised for its overbuilt frame and progressive suspension design, making it a favorite for park and shuttle use. While it excels in downhill stability and fun, its weight and slack geometry may not suit all riders, especially those prioritizing climbing efficiency.

Pros
  • Predictable handling and suspension action

  • Overbuilt and bombproof frame

  • Progressive suspension design suitable for a wide range of sag settings

  • Excellent for park and shuttle use

  • Good value for money

Cons
  • Heavy (over 40lbs)

  • Slack head tube angle may not suit all riders

  • Not the best climber

  • Primer grey color may be too muted for some

  • Thin paint prone to wear

Key Quotes
The Transition simply does not have any quirks.
BIKE Magazine logoBIKE Magazine
It would be the perfect park and shuttle rig for someone who wants to own a 170mm big bike but would not get to ride it as often as they would like.
BIKE Magazine logoBIKE Magazine
Transition's ethos of 'Engineered to Party' and moniker of the Spire being a 'nimble bruiser' are spot on.
