This folding bead electric mountain bike tyre is equipped with Vittoria's renowned Graphene 2.0 compound, which reduces rolling resistance and increases range and battery life. Raising for bar for E-Enduro performance on mixed terrain, this MTB tyre is also kitted out with a deep siping in the direction of rotation. This allows you to benefit from a fast and steady roll, while also opposing drift. The stepped leading-edge rolls like a ramp, but digs in on climbs, making e-Mazza a top choice for both front and rear use. Substantial room was designed into the centre tread to provide braking traction, while also accelerating cleaning. - Aggressive profile with ample sipe spacing for mixed terrain - Progressive sipe-width pattern provides tactile grip at the knob surface, without sacrificing speed or grip - Graphene 2.0 compound reduces rolling resistance, increasing range and battery life Cornering on the e-Mazza is handled by Vittoria’s trademark progressive sipe width technology, which gives a gummy inside effective edge, but without the instability that competitors experience on the outside of the tread. e-Mazza’s generous tread depth claws into a range of terrain, and is stabilized with Vittoria’s proprietary 4C compound layering process. Four separate Graphene 2.0 compounds are layered, allowing the surface of the tread to remain tacky, while the base remains planted. This ensures each effective edge is kept in place under high cornering and braking loads, leading to reduced rolling resistance, and increased wear life.

Ideal for taking on steep inclines and speedy sprints, it delivers a championship-winning performance on every outing. Technologies Graphene 2.0 Compound: Vittoria’s unique Graphene compound is superior in rolling performance, grip, traction and longevity. This compound provides the performance benefits required for competitive, consistent racing output. The Original Graphene Compound raised the bar for performance evenly through all disciplines, whereas Graphene 2.0 pin-points the performance requirements from each cycling discipline and enhances them for speed, grip, durability and puncture resistance. 4C Compound: Exclusively developed by Vittoria and achieves high-end performance. The 4C is a layering process using 4 separate rubber compounds within the same tread. The 4C construction provides unmatchable versatility in both the central and side tread areas. The finished product is extensively tested to ensure it meets the competition level performance that road and off-road cyclists demand, and benefits the rider significantly, providing better rolling efficiency, better grip and puncture protection.

Hutchinson measures its tyres on ride comfort, rolling resistance, grip, wear life, toughness, and weight, and the Performance is off the charts in every category. You get the same fast, grippy Eleven Storm compound as all Fusion 5 series tyres, paired with a more robust Kevlar Pro Tech flat protection layer. With unparalleled, uncompromising ride in our broadest size range, it’s a tyre for every road. The Hutchinson Fusion 5 Performance 11storm is a lightweight, performance-focused road racing tyre that's been designed to excel at competitive racing. It features Hutchinson's ElevenSTORM compound, which lowers rolling resistance across the board for a remarkable uphill speed advantage as well as a grippy all-around performance. The Performance version of the Fusion 5 family is the perfect harmony for all cyclists wishing to go fast and far. Associated with a Kevlar® reinforcement under the tread, it will reassure the most nervous and offer durability superior to 4,000 km. It offers the perfect compromise between performance and comfort, grip and durability.
This tyre features Hutchinson's Race Ripost Enduro compound for a lightweight performance. Plus, the extended lateral knobs on the tread offer improved lean angle grip, ensuring you have extra stability in wet conditions.
This tyre's tread keeps a remarkable grip in tough weather, and sports a dynamic profile that ensures puncture resistance, so nothing gets between you and your ride.
Perfect for both training and racing, this tyre is built to handle all the challenges that are associated with riding on rough roads. This makes it a perfect choice of upgrade for riders who want excellent comfort and control. Technologies: Challenge Handmade Clinchers (HCL): Our Handmade Clinchers are made from the same materials and processes as our handmade tubulars but instead of sewing an inner tube inside the casing is wrapped around an aramid bead to form a tire that fits on a clincher rim. The HCL is moulded flat, not in a horseshoe like a TLR or VCL. This shape allows the casing to naturally deform over surface imperfections and minimize rolling resistance. A tubeless tire is moulded in a U-shape to make the sidewalls rigid, so the system does not “burp” or lose air when it deforms after it encounters a surface imperfection. The tubeless tire’s stiff sidewall compromises its ability to equal a supple HCL with a latex inner tube.

Hand Assembled Challenge uses the latest technical materials such as corespun for the inner casing of these tyres. This material produces a very high TPI (threads-per-inch) count to ensure the ultimate in strength, suppleness, and low weight. This casing is then hand glued on to the tread, which has previously been installed and inflated on a rim. This means that when the assembled tyre is inflated, it provides more precise handling, lower rolling resistance, and better grip. Shock Absorbing The best materials have been used to obtain consistent grip over uneven terrain and reduce the vibration feedback to the rider, helping you to maintain grip and control on even the longest and roughest races. The advanced design reduces wheel skipping and jumping over rough surfaces, ensuring efficient grip and helping you to maintain your speed. These tyres also feature a double layer of Challenge's PPS (puncture protection system) between the tread and casing, to give you confidence when blasting over tree roots and sharp rocks. Technologies: Challenge Handmade Tubulars (HTU): Our Handmade Tubular (HTU) tires perform better than any tubeless system! Therefore, they are raced by all the top athletes and teams in every cycling segment. The latex inner tube we cradled inside the high-quality casing that is sewn shut, forming a soft protective layer for the delicate tube. A base tape is glued over the sewing for protection and to absorb the adhesive later applied to hold the tubular on the rim. The carcass is mounted on a rim, inflated and a special natural rubber tread is precisely glued on top. Puncture protection layers and sealants can be applied to the finished casing, depending on the tubular’s use.
Cyclocross World Champion for years. Whether a Pro or just a hardcore rider Grifo is the tyre you need. Unbelievable grip with no rolling resistance compromise. All tubular and open tubular produced by Challenge are special products. Machines are not able to produce them and the manual skill required in each step to obtain a good quality standard is very high. 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. Our 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 tubulars 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. Classed as one of the best all-around cyclocross tyres every created by Challenge, this tyre excels in wet, dry, soft packed, rocky and root-infested course conditions.
