CHALLENGE Tubular MTB Two 27.5 | 650B x 2.2 Tubular
The MTB Two of Challenge was developed for use on fast race with a hard surface.
Latex material increase an extremely fine carcass with 300 TPI and the inner tube to puncture protection. Thus the weight of the tire is kept low.
The offensive profile compared to the One, ensures better acceleration.
The large spaces between the studs ensure a good self-cleaning and braking traction.
The Tubular system allows the use of less air pressure, which offers more comfort and just relieved on longer routes the postural muscles and can thus tiring the driver later.
The composite tube and tire provides weight savings and increase the breakdown protection, since the tube can not be "crushed" on the rim.
Furthermore, the jacket in extreme braking maneuvers do not slip off the rim, since it is glued.
