It's not every day you get the chance to see something as exotic and beautiful as this, the lightest road bike in the world. The impossibly-skinny Spin Custom frame is adorned with a whole host of featherweight parts to bring the total build weight to a little over 2.7kg, barely over 6 pounds.

  • In all its minimal glory, the 2.7kg Spin Custom Light Bike.
  • The front end has a set of AX Lightness Orion calipers, and a set of B-T-P downtube shifters which weigh a scant 9g for the pair.
  • Upgraded from its previous iteration under Mai, the bike now features a 10-speed drivetrain with a SRAM RED modified rear derailleur at just over 100g.
  • Fairwheel used a modified Record front derailleur.
  • Crank duties go to a prototype Mythic crank, not available at your local dealer.
  • These Aerolite pedals were an extra lightweight one-off version from the manufacturer, and then drilled out for extra weight savings.
  • We thought it interesting to juxtapose this insanely light bike with some heavyweight machinery.
  • The bike is probably lighter than the laptop you're using to look at this very image.
  • The 30g Dash front hub.
  • The rear hub is a mad 84g, but production versions will be just a little over that.
  • The saddle and seatpost are one bonded carbon unit that weigh less than 80g complete.
  • The Spin used a freaky style of carbon that we'd never seen before.  Even Jason from Fairwheel doesn't know what it is.
  • One of Fairwheel's other projects was a very special Parlee aero frame, turned into a three-speed fixed gear with an internal rear hub.
  • The bike's paint job is a reveal - white paint, scratched away to reveal the black carbon underneath.
  • Fairwheel's custom top cap.
  • The bike just looks sick.
  • After the show, everything gets locked up in Fairwheel's booth.
