Summary

The CUBE Reaction trail bike series offers a mix of performance and value, with models praised for their acceleration, climbing efficiency, and component quality. However, some reviews note a harsh ride on descents, limited mud clearance, and tyres that struggle in wet conditions. The bike is often compared to the Specialized Epic Hardtail and Canyon Exceed CF SL 7.0 for its trail capabilities.

Pros
  • Instant acceleration

  • Impressive spec with well-chosen components

  • Great for sprinting up short, sharp climbs

  • Fox 34 fork is decently stiff with a supple GRIP damper

  • Cracking value for the price

Cons
  • Harsh ride on descents and rough trails

  • Tyres are thin and need higher pressures, adding to a jarring ride

  • Limited mud clearance

  • Tyres struggle in wet conditions

  • Long stem slows reactions on tight tracks

It's cracking value and much more capable in the rough than the rest of the range if you like hacking about in the woods

Cube Reaction C:62 SL review

Jul 2020 · Tom Marvin

Fast reactions to pedal inputs help on climbs, but the stiff chassis affects descending capability

Highs
  • Instant acceleration

  • Impressive spec, with well-chosen components across the board

Lows
  • Harsh ride chokes descending speed and rough-trail acceleration

  • Tyres are thin and need higher pressures to prevent punctures, adding to the uncompromising ride feel

Cube Reaction TM review

Apr 2018

Cube's Reaction TM is a harder hitting version of their high-value aluminium Reaction hardtail range, pairing a sturdy 130mm fork up front with fat 2.6" tyres on 27.5" wheels. It's cracking value and much more capable in the rough than the rest of the range if you like hacking about in the woods, but there are harder edged weapons out there if you want to go full gonzo.
