Reviews

Summary

The Specialized Roubaix is celebrated for its exceptional comfort and innovative Future Shock suspension, which effectively smooths out rough roads, making it a standout in the endurance category. While it offers a balanced ride quality and impressive handling, some reviews note its higher price point and the lack of certain adjustments in the Future Shock system as drawbacks. Comparisons often highlight its relation to the Specialized Tarmac, with the Roubaix being the more comfort-oriented option.

Pros
  • Exceptional comfort with Future Shock suspension

  • Balanced ride quality and impressive handling

  • Innovative design with Rider First Engineering

  • High-quality frameset across all models

  • Versatile for various riding conditions

Cons
  • Higher price point compared to rivals

  • Future Shock system lacks some adjustments

  • Heavier wheels may affect speed

  • Some models lack tubeless-ready tyres

In the past I definitely would not have considered myself a Roubaix customer, but now I’d have to reconsider.

Specialized launched the Roubaix with the tagline 'smoother is faster' and I’m inclined to agree.

Gallery: Peter Sagan's non-Di2 Specialized for Paris-Roubaix

Oct 2021 · Ben Delaney

Shimano’s latest R9200 Dura-Ace group has a few options, but none of them include mechanical shifting; it’s Di2 only for Shimano’s top racing group from here on out. At Paris-Roubaix, Peter Sagan has voted with his bike that he prefers still mechanical shifting for the world’s hardest cobblestone race, thank you very much. In 2018, … Continued

Specialized S-Works Roubaix review

Jun 2020 · Stu Bowers

The 2020 Specialized S-Works Roubaix is as comfortable as previous generations while matching the speed of the Tarmac SL6

Highs
  • Nipping at the Tarmac's heel in terms of performance

  • But with much greater comfort and increased versatility at the turn of a dial

  • Impressively light

  • Fantastic control

Lows
  • To buy an S-Works means nearly £10k

  • But cost is subjective

Specialized Roubaix Comp Ultegra Di2 2020

Feb 2020 · Stu Kerton

Fast, sweet-handling bike with great comfort levels, but I'd like some control over the spring rate

Highs
  • Handling unaffected by rough roads at speed

  • Ultegra Di2 groupset is faultless in use

Lows
  • No lockout on Future Shock, which means it bounces under hard efforts

Review: Specialized's all-new Roubaix, a Spring Classics road bike for everyone

Apr 2019 · Veronika Benson

At the peak of the Spring Classics, we had the chance to put Specialized’s all-new Future Shock 2.0 front suspension Roubaix endurance road bike to a true test on the bergs, pavé & wind swept roads that define those iconic one-day races. While the Roubaix certainly proved its mettle with Phillipe Gilbert winning Paris-Roubaix on …
