This Challenge MTB One -Tubular Mountain Bike Tyre is no longer available although you may find similar or newer versions below:
The new MTB One tubular tyre! - The special mud-free large tread to grip the worst mud and stand fast and agile at the same time. Jump from everywhere to everywhere. No brainer. Just race.
|Wheel Size:||26" (559)|
The casing is produced with the latest technical materials like Corespun (a cotton and polyester combination). Corespun is a thread from which we obtain a very supple and strong casing with low weights. The casings have a high TPI count that can reach over 300 TPI. Challenge's production process avoids any vulcanisation process to enable all materials to keep their suppleness and flexibility.
The tread is slowly hand glued on the casing which is previously mounted and inflated on a rim. By using this method the tread is relaxed on the casing and does not suffer any tension when inflated. The result of this is a lower rolling resistance, increase in comfort, more precise handling of the bike and better grip. Hand made tubular are well known by professionals and is this type of tyre that is preferred for the long stage races.
To give the best possible grip in curves Challenge uses the most updated materials to obtain flexibility, suppleness and this results in absorption of irregular surfaces giving to the cyclist the best possible contact patch. The wheel avoids jumping and the tyre will deform and absorb the irregularities acting in some way as a shock absorber. A special fabric is placed between the tread and casing to increase puncture resistance PPS (Puncture Protection System) technology.
Comfort means reduction of harmful vibrations for the wrists and neck, these vibrations, will end causing inflammatory problems, as a hard tyre will transfer all the vibrations directly to the racer body.
These tyres are for mountain bikes and intended primarily for off road use, the knobbly patterns provide grip when steering and traction when applying power to the pedals. There is usually a tyre to suit the conditions in which you are riding in so the right choice is important. On dry days a narrow tyre with a smoother central tread can be used, but on a wet day a wider tyre with a deeper knobbly tread pattern is essential or you could be the one in contact with the mud.
In 2003 Challengetech created its own brand “Challenge”. Challenge, as the word says, wants to point out how difficult and exciting it is to keep the tradition of high quality products, created with obstinacy, with the steady research of special materials and through handcrafted processes. Since the 2000s, Challengetech has being producing tubulars for other brands, thanks to the constant use of these products in the professional cycling.
