Sounds good, pressures seem to be super critical to how the bike behaves. I've mine earmarked for mostly tarmac > beach duties so a sweet spot will have to be found.
Build is coming along great, I've got the rims in from germany and have drilled one of them and will be drilling another tonight. Shed about 220g from the first one. I've also ordered my hubs, DMR 6 pawl and a single speed screw on as well. Soon as I get them I'll drop the stuff off at Big Al's, then all I need are a few other bits and tyres and should be good to go hopefully mid January.
