T1sl High-Performance Road

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

The T1sl is a no-holds-barred race bike, born of years of our titanium expertise. It’s proof that weight-weenie status isn’t limited to carbon and that titanium is still the material of choice for discerning riders. In a sea of carbon Litespeed Titanium stands its ground. The T1sl is super light with high performance road geometry. In fact it is the lightest production hand-made titanium frame on the market (averaging 995 grams per size small).

It's new innovative 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, triple butted, asymmetric chain stays for maximum power transfer. Oversized and bi-axial ovalized downtube provides maximum performance and stiffness. A meticulously engraved 44mm head tube yields precise handling. The PF30 bottom bracket is compatible with virtually every crank on the market. The T1sl accepts caliper brakes only.

Size specific tubesets guarantee consistent performance for each frame, whether a size XS or a size 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 grades, we go above and beyond to deliver the most premium cycling-specific tubesets.
