Hey guys. I'm getting close to Xtracycle time, but I'm now trying to decide what to use as a base. I generally ride road bikes, but given that I'm 240 pounds, I don't think skinny 700c wheels are gonna hold me, my girlyfiend, and all our groceries! So, I guess that I need a 26"er, probably a rigid steel framed MTB. What I think is that I could find a Specialized HardRock pretty cheaply, and they seem pretty solid. What are the realistic options for tyres though? I don't want to run huge knobbly soft tires that're going to eat all my pedalling energy. I guess that something like moustache bars of maybe North Roads will be good, and perhaps a nice sprung Brooks, like the B66.
Anybody got any thoughts on what works well?
