Grand Prix Urban vs High Roller II review

Features

• PolyX Breaker

  Puncture-defence

  With our PolyX Breaker®, we bring our car expertise to the bicycle tire segment: Polyester has been used successfully for years in car tires and been tried and tested many times. The extremely resistant polyester fibre is woven tightly crosswise. In this way, a very high fabric density is reached which not only makes the Breaker more resistant to foreign objects but is also especially resistant to punctures. The rolling resistance is also not negatively affected by the PolyX Breaker®.

• BlackChili

  It’s all about how you mix it

  With our unique tread compound, which is produced only in Germany, we have revolutionised the sport of cycling. With the legendary BlackChili Compound we have answered the eternal question of the best balance of grip and rolling resistance for cycling.

  Regular test wins confirm the measureable and noticeable advantages for the cyclist, established in the laboratory and on the road. The latest polymers as well as specially developed carbon black particles and filler materials guarantee unique performance

• 3C MaxxTerra An intermediate compound configuration used in select mountain tires. 3C MaxxTerra is softer and offers more traction than 3C MaxxSpeed, yet provides better treadwear and less rolling resistance than MaxxGrip.

• 3C MaxxGrip 3C MaxxGrip uses the softest rubber compounds to offer the ultimate in grip and slow rebound properties for unparalleled traction in downhill applications.

• Wide Trail Wide Trail (WT) construction optimizes the tire’s tread layout and profile on today’s modern, wider rims. Traditional tires are designed around older, narrower rims and can create an overly square tire profile, leading to less than optimal performance. WT tires are optimized for a 35mm inner rim width but are proven to work over a range from 30-35mm inner rim widths, depending on the rider’s preference. Maxxis Wide Trail XC tires are optimized for use with 30mm internal width rims, but they will perform well on rims as narrow as 25mm. Maxxis does not recommend rims wider than 30mm or narrower than 25mm

• Tubeless Ready Tubeless tires provide the rider with many benefits: the ability to run lower air pressures, which improves traction; lower rolling resistance when compared to a tube-type tire; and less chance of flatting because there is no tube. Liquid sealants should only be used in the following types of tires: tubeless road, tubular, and tubeless ready. The use of liquid sealants in any other Maxxis tire will void the warranty.

• EXO An extremely cut-resistant and abrasion-resistant material added to the sidewalls of select mountain tires. This densely woven fabric is also lightweight and highly flexible, ensuring that the performance of the tire remains unaffected. Choose EXO Protection for exceptionally rocky, treacherous trails where the chance of sidewall cuts and abrasions is high.

• Downhill (DH) Two layers of casing material are used from bead to bead, providing additional protection and sidewall stiffness for downhill applications.

• Double Down (DD) DoubleDown (DD) is the next step in the evolution of the dual-ply tire casing for enduro racing. Two 120 TPI casing layers reinforced with a butyl insert provide the enduro racer with the support and protection of a downhill tire, but in a lighter package.
