Summary

The Trek Procaliber is a lightweight cross-country bike praised for its stiff, accurate frame and innovative IsoSpeed technology, which enhances comfort on rough trails. However, its performance is mixed, with some reviewers noting issues with steering precision and the effectiveness of the IsoSpeed system being limited to seated riding. The bike excels in efficiency and climbing, thanks to its SRAM Eagle groupset, but some components like the tyres and fork stiffness have been points of criticism.

Pros
  • Lightweight and stiff frame

  • Innovative IsoSpeed technology for enhanced comfort

  • Efficient SRAM Eagle groupset for climbing

  • Quality fork and accurate tracking

  • Internal cable routing and Di2 compatibility

Cons
  • IsoSpeed benefits limited to seated riding

  • Poor steering precision in some models

  • Soft carbon wheels and frame affect handling

  • Some components like tyres and fork stiffness criticized

Key Quotes
The accurate-tracking frame and quality fork mean you can drive the front end hard, once you’re used to the bar.

Trek Procaliber 9.7 SL review

Mar 2016 · Guy Kesteven

Impact-smoothing super-light racer, but needs fatter tyres and pedalling bounce can be irritating. Buy if you like your greyhound hardtail with a side order of comfort, and are prepared to make a kit tweak or two

Highs
  • Svelte, contemporary frame, isospeed pivot smooth buzz, rapid ride

Lows
  • Smoothing tech can be a double-edged sword, needs fatter treads to get the most from it
