Speed. In cross country racing, this is all that matters. To achieve this, however, a cross country mountain bike tire needs to deliver on all fronts for various different kinds of terrain. Our tires have this covered, though, and with a World Championship level of confidence to boot. You can expect fast tread patterns with plenty of grip in the corners and on climbs, plus durable constructions that won't leave you flatting out at the pivotal moment of your race. Consider them the total package when it comes to race-day performance.
