Yipee! Got my Krampus back from the shop and those big 29x3 tires are now tubeless. Does it make a difference? You bet it does. The Kramp now rides the way I always hoped it would ride. Much more lively and responsive with those lighter wheels, plus a softer ride with better traction.
... and the single speed addiction continues. Dropped off the Pugs 2 at the same time. Soon to be another single speed for me to ride.
