T1sl High-Performance Road
The lightest production titanium frame featuring highest stiffness-to-weight ratio of any titanium road-bike on the market.
Light makes right.
So say the climbers. The Billy goats. The grimpeurs. Where the air is thin, KOMs are your holy grail. If there’s one thing better than a buoyant ascent up a long climb, it’s being the first to attack the descent…solo.
There’s but one bike to take you to the top: the T1sl.
While the T1SL is Litespeed’s signature lightweight machine, it’s no one-trick pony. Adept at carving corners and holding speed on the flats, T1sl is a no-holds-barred race bike that happens to defy the scales, thanks to decades of our titanium expertise. And for the discerning cyclist, titanium still reigns supreme as the king of lightweight race bike capability. At 995 grams in size small, the T1sl remains the lightest production handmade titanium frame available on the market.
How we make a performance race bike this strong, this stiff, this comfortable and this light is what sets the T1sl apart from all others. It starts with an innovative top tube, handcrafted from a single sheet of aerospace-grade 6AL/4V titanium, shaped into a multi-faceted tapered tube that slashes weight while increasing torsional stiffness.
The bike stays race-day stiff with a pair of oversized, triple-butted asymmetric chainstays designed for unyielding power transfer. The downtube completes the package, oversized and bi-axially ovalized to provide optimal performance and stiffness. At the front, a beautifully engraved 44mm headtube delivers precision handling. With a PF30 bottom bracket, the S1ls compatible with nearly every crankset available. The T1sl accepts caliper brakes only.
To ensure every T1sl is built to precision tolerances that ensure the perfect ride in every size, each frame has size-specific tubesets, guaranteeing consistent performance, regardless if you’re a size XS or XL. We also use the highest-quality titanium available, with our cold-working making it even better. While our competition settles for softer, more easily-processed grades of titanium, we go above and beyond to deliver the most premium cycling-specific tubesets. That NASA comes to us for our materials choice advice is no mistake. And the result speaks for itself.
The finest lightweight race bike available is also fully customizable as well. Choose our standard decal presentation, our etched finish, even a custom paint upgrade. If you’re looking for a SRAM build, rack or fender mounts, or anything in between, we can accommodate nearly any request, whch may require additional costs and lead times. The options are endless; just call us to make the T1sl a true custom ride.
