Thin thread and low rolling resistance to reach your maximum speed and maintain it with the less effort. Thanks to the natural rubber and the thread design the grip and rolling resistance are equally outstanding.


Tubular tires are, well, tubular. They are sewn shut around a Seamless Latex Inner Tube, already in a tube shape, and are mounted and glued directly on a rim, rather than around a tube. However, they require a purpose-made tubular rim that would usually only be used on race day to avoid damage. Open Tubulars mount like a standard clincher, but are made using the same artisan Handmade process as our Tubulars and maintain most of the suppleness and ride quality gained from a Handmade Tubular.


An extra layer of uniquely-crafted fabric with highly resistant properties sits between the casing and the tire to reduce the risk of punctures. Tires intended for use in intense conditions with a high puncture risk are reinforced with a second PPS layer beneath the casing.


Thread count plays a major role in the weight, suppleness and durability of Tubulars and Open Tubulars. The higher the number of threads per inch (TPI), the thinner each individual thread, making a thinner and lighter casing and a more supple tire. Our lower TPI casings are thicker and more durable.
