After much procrastinating I finally got myself some 29id carbon wheels built up and mounted up my hans damph/Nobby nic combo from my old narrow alu wheels. Straight up it was drag central on the rear.. Thought the rotor was rubbing when on the flat trails. On the downs it wasn't as noticeable but this bike (130mm 29er) is my all rounder, it still needs to peddle reasonably efficently on hardpack.. So i pulled off the NN and put on a new rock razor.. That was even worse rolling wise, dunno if the wide rim squared it off too much but it felt like absolute shite..
So, with dread, I mounted up my old 2.25 ardent and surprisingly it was a much better tyre on the wider rim and lower psi.. I fkn hated that tyre front or rear, would have rather used a crossmark but in the dry it did really well..
So now to the point, what sort of decent volume rear tyres that roll reasonably fast are you lot running? The hans damph on the front ain't fast but it does all mountain and xc good enough for me.. The ardent (shudder) is doing the job atm but what else is out there?
