T1sl Disc High-Performance Road


The lightest production titanium frame featuring highest stiffness-to-weight ratio of any titanium road-bike on the market.

The T1sl with disc brake option incorporates a clean flat mount road disc specific design with a 12mm thru axle and internal hydraulic cable routing.

Litespeed's Titanium flagship model is a no-holds-barred ultra-performance bike, born of years of our titanium expertise. It's proof that weight-weenie status isn't limited to carbon and that Litespeed titanium is still the material of choice for discerning riders. In a sea of carbon, Litespeed Titanium stands its ground. High performance road geometry, the T1sl Disc is the lightest production disc specific USA hand-made titanium frame on the market (1,169 grams size medium disc brake model).

The innovative T1sl top tube is created from a single sheet of 6AL/4V titanium to make a unique multi-faceted tapered tube that reduces weight and increases stiffness. Oversized and bi-axial ovalized downtube provides next level performance and stiffness. A meticulously engraved and butted 44mm head tube yields precise handling. The PF30 bottom bracket is compatible with virtually every crank on the market. Size specific tubesets guarantee consistent performance for each frame, whether a size XS or XL.

Each Litespeed Titanium Bike is formed from the highest-quality titanium available, and our cold-working makes it even better. While our competition settles for softer, more easily processed tubing, Litespeed goes above and beyond to deliver the most premium cycling-specific tubesets.
