The Unknown Bike Singularity is the evolution of the popular fixed gear LV2 frame, and now it is available as a complete bike. The Singularity frame combines a modern tube set and updated geometry to create the ultimate race machine. This track-oriented frame now features an integrated aero seatpost, a carbon/alloy fork, and other high-quality components. This is a significant step for Unknown Bikes… and you. Comes with carbon/alloy fork. 

Bicycle Components

Unknown Bicycles Singularity Frame is made of high-grade, hardened Aluminum 6066 T6. Our Carbon (12K) fork comes with a 1 1/8″ aluminum neck and 30mm rake. The headset is an integrated SB, 45×45. The fixed gear bike frame uses a 90mm stem and Unknown Compact 420mm handlebars. Included brake levers are ZST single speed with our Unknown brake set. The chain arm is 165mm and 130 BCD. The chain wheel is our Unknown 48 tooth, 130 BCD, at 0.5 x 1.125”. The rear cog has 17 teeth. The seat post and saddle are made by us at Unknown while the tires are 23c. The seat post measures 27.2mm x 300 mm with a 22mm offset. Included rims are Unknown fixed gear 28d rims. The bottom bracket is 68x103mm, BSA with a Square tapper.

Carbon fork

We also chose the carbon/alloy fork over the standard alloy fork for the European market. This fork increases the price a bit, but it makes a big difference in performance and comfort, not to mention improving the overall look!
