Ultimate confidence in mixed to coarse loose conditions For riders who face mixed conditions week after week, the Terreno T80 would be the choice. T80 is optimized for mixed to coarse loose terrain, it's the most versatile tyre in our cyclocross series. The tyre's mix of tread types supports speed on the straights and biting security while off camber or slogging through mud, but it doesn't muddy the connection between you and whatever surfaces the course has in store. When conditions do turn sloppy or soft, the tyre's spacious tread shrugs off mud and clingy, loamy soil.
