For the previous two Kiwi Brevets I have gone with the comfort of a 26er fully. This time I am going with a 29er fully-rigid. Roll-a-bility versus comfort is the plan. I'm also planning to carry all water on the bike rather than have 3 litres of it on my back, to cut back on "butt trauma". I am foregoing aero bars and bar ends for Woodchipper drop bars which also give a lot of different hand positions. The KM might be a tad lighter if I manage to tubeless the tires.
2014 set-up. Surly Karate Monkey 29er.
