Summary

The Rocky Mountain Altitude is a versatile enduro bike praised for its adjustable geometry, supple suspension, and excellent traction on difficult trails. It excels in descending and rough terrain, though some reviews note it could be more efficient on climbs. The bike's Ride 9 system allows for significant tuning, catering to a wide range of preferences and riding styles.

Pros
  • Adjustable geometry with Ride 9 system

  • Supple and effective suspension

  • Excellent traction and stability on difficult trails

  • Versatile with many spec levels and price points

  • Clean, fully tubed internal cable routing

Cons
  • Less-than-super-efficient climbing prowess

  • Overwhelming number of Ride-9 settings

  • Rear shock requires extra pressure compared to factory recommendations

Key Quotes
The suspension feels uniquely supple, fast, and totally unencumbered, soaking up bumps better than Jonny Moseley in his prime.

The Altitude’s leaner looks give you a sense that this bike would be pretty good at climbing and trail rambling too.
