I'm sure you could run them tubeless with sealant

Ok, thought I'd check what the weight difference it would be to change to No Tubes kit and the much faster rolling (or so I've been informed) Shwalbe Marathon Racer 26" x 1.5" tyres and I can save HALF A KILO PER WHEEL going with them! 0_o
Have just ordered them from chainreactions.
No wonder the new build felt so bloody slugish...
