The Aspen ST (or Fastpen, as it’s sometimes known) is a new ultra-low-profile XC tyre based on the Aspen. Eagle-eyed race fans may recognize the Aspen ST tread pattern from spy shots, but it's never been publicly available until now. Designed to be even faster than its predecessor, the Aspen ST is sure to catapult you to the podium, just like it helped Nino Schurter to countless World Cup wins. The Team Spec Aspen and both versions of the Aspen ST are available in 29x2.40 and 29x2.25 options.
An all-new MaxxSpeed compound for the Maxxis cross country (XC) line. The new MaxxSpeed uses silica as a filler in the rubber polymer creating a compound that performs better across the board compared to the old 3C MaxxSpeed. Racers benefit from reduced rolling resistance and improved wet traction.
The use of three different durometers of rubber in a single tyre–Maxxis’ 3C technology–set our mountain bike tyres apart from the competition over the past two decades. But when it was time to develop a new topshelf XC compound, we focused on performance above a specific number of compounds. Maxxis engineers used knowledge gained from the development of our full-silica road racing compound and began testing formulations suited to off-road use.
