my honest opinion is that minion 2.35s are small to begin with. anything smaller certainly doesnt belong on a bullit. sure you can put xc tires on a bullit but then it begs the question of whether you have the right bike....i know, easy for me to say but i would never do that to my old bullit. would be like pulling up to a biker bar on a vespa. my opinion anyway and i have been known to be wrong believe it or notemptybe_er said:I've been running 2.35 Minions on my Bullit for agressive trail-riding but the climbs kill me with the weight and rolling-resistance. I have a set of 2.1 Crossmarks and a set of 2.1 High Rollers (both have usual signs of fr/rr tread-wear). I'm playing with the idea of mixing the tread patterns using the better tire from each set. Crossmark up front or High Roller up front? It's kind of an experiment. . . anyone want to chime in?
