Summary

The Boardman SLR series is praised for its excellent value, offering performance and features typically found in more expensive bikes. Reviews highlight its comfortable ride quality, predictable handling, and versatile use for racing, training, or commuting. The carbon frame and fork, along with quality components like Shimano 105 groupsets, contribute to its positive reception, despite some noting minor compromises in weight and tyre feedback.

Pros
  • Excellent value for money

  • Comfortable and reassuring ride quality

  • Versatile for various riding conditions

  • Carbon frame and fork for lightweight and stiffness

  • Quality component spec including Shimano 105 groupset

Cons
  • A bit heavier than more expensive models

  • Tyres may mute feedback

  • Limited tyre clearance due to calipers

  • Basic wheels on some models

Key Quotes
It’s a bike that punches above its £750 price tag in performance, with a comfortable, reassuring ride quality.

The result is a ride that’s as fast as it’s comfortable, with impressively controlled handling from the front end’s stiff carbon fork and oversized, tapered steerer.

Boardman SLR 8.9 Carbon review

Jul 2019 · Simon Withers

The Boardman Road Team Carbon is dead. Long Live the Boardman SLR 8.9 carbon!

Highs
  • Quality modern-looking carbon frame and all-carbon fork, great commuter/sportive ride, tubeless-ready wheels

Lows
  • It’s Tiagra rather than 105, not quite as light as some aluminium bikes, lack of rack mounts and slightly high bottom gear
