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
