Summary

The CUBE Reaction trail bike series offers a mix of performance and value, with models praised for their lightweight frames, efficient power transfer, and quality components like Shimano transmissions. However, some builds suffer from basic forks, heavy wheels, and tyres that lack grip in wet conditions. The bikes are noted for their agile handling and stable steering, though some riders may find the ride harsh over rough terrain.

Pros
  • Lightweight and stiff carbon frame

  • Quality Shimano transmission

  • Agile and stable handling

  • Good value for money

  • Decent suspension performance in higher-end models

Cons
  • Basic and heavy forks in some models

  • Tyres with poor wet-weather grip

  • Heavy wheels and narrow rims

  • Harsh ride over bumpy terrain

  • Some components may need upgrading

Key Quotes
If you prefer a shorter bike and want a machine that responds well when you lay the watts down, then the C:62 is an excellent upgrade investment

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 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.
