Our new model 41 trials tire is now available for the front and rear of the TW.  This tire is designed to be a 50/50 road/dirt trials use tire.  It has been extremely impressive in our off and on-road testing. Trials tires are excellent on the road and conform to off-road terrain like no other tread design. The only downside to trials tires is that they tend to slick over in the mud, so they are much more suited for dry conditions. Comes with one 140/80-18 front tire. HD tubes available separately. DOT legal.
