Not radically changed, almost conservative, the Thunderbolt stays true to its intentions.

The Rocky Mountain Thunderbolt BC Edition is guaranteed to put a smile on your face: it was by far the most agile bike in this group test.

Highs
  • Very playful

  • Beautiful frame

  • Comfortable suspension

Lows
  • The rear linkage lacks support

  • Nervous at speed

  • Small brake rotors

Review: Rocky Mountain Thunderbolt Carbon 70

Aug 2018 · Mike Levy

Like the other new bikes, you'll find blind pivots on the Thunderbolt that make for some pretty clean lines, as well as sealed bearings all around (including the lower shock mount) that replace the bushing system Rocky used previously.

Highs
  • Playful personality

  • Supple suspension action

  • So much adjustability

Lows
  • Requires more effort to ride fast on difficult trails than a 29er

  • Finicky suspension setup if you want to get the most out of it

  • So much adjustability
