Signature Track Frame

The Unknown LV3 is a lightweight, high-performance track/fixed-gear bike frame designed for urban riders and track enthusiasts. It features aero-inspired geometry, making it ideal for aggressive riding, whether on the streets or the velodrome.

Bicycle Components

Unknown Bicycles LV3 Frame is made of high-grade, hardened Aluminum 6066 T6. The fork is our Carbon (12K) with 1 1/8” aluminum neck and features a 30mm rake. The headset is an integrated SB, 45x45. 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 opted for the full carbon fork instead of 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!
