Surly Midnight Special Review: If it Ain't Broke...

Feb 2026 · By Nic Morales

In his Surly Midnight Special review, Nic takes this newly updated classic through its paces to determine whether it's still relevant today...

Highs
  • Exceptional ride quality, especially given the price.

  • Dual wheel size compatibility and clearance are still relevant a decade on, albeit unofficially.

  • Despite being an all-road bike, the frame has an appropriate number of mounts that pair well with the steel fork version for an all-action bikepacking rig.

  • The unique thru-axle delivers versatility and utility.

  • Simple, elegant, and timeless design.

Lows
  • The carbon fork feels like it’s one feature—the crown eyelet—away from being a real asset.

  • The supplied build kit feels useless to anyone save for pavement-focused riders.

  • The higher-end build kit is a little pricey, though it’s difficult to mark that as a con given both the $2,500 steel fork and $1,099 frameset options.

  • If you’re not a fan of 650B wheels, this might not be the best option for you.
