S33 Pro, in a few words
What it does
The S33 Pro is Tufo's training tubular, and the best seller of the whole range. No exotic fibre, no 400 TPI casing: a solid construction, a compound that lasts, and a price that lets you wear a tubular out without a second thought. It is the tubular you fit in November and find again in spring.
The construction
60/90 TPI casing — robust rather than supple —, carbon black compound for mileage, and a permitted pressure that goes up to 12 bar in 21 mm. The fine tread limits rolling resistance without compromising grip on dry or wet roads.
Tubular or tubular clincher
The S33 Pro comes in two versions. The standard tubular is glued or fixed with double-sided tape to a tubular rim. The tubular clincher (reference C S33 Pro) is a sewn tubular whose base tape is profiled to fit an ordinary hooked rim, without glue: the build and comfort of a tubular, on the wheels you already have. In 21 and 24 mm, black or tan sidewalls.
