what tires are you using?
I blew a Maxxis Ikon (2.35). Slashed a hole underneath one of the cornering knobs where I drilled a rock. Cut is about 1/2 inch in total. I picked up a Nobby Nic at REI because I want to ride Sunday, but not sure I'm gonna like in combo with the Ikon up front (was running the Ikon 2.35 front and rear), the blocks on the NN are huge. Did order an Ardent Race for the rear which will probably end up being a good mix with that Ikon up top. Been a fan of the Ikons and I know that I am harder than most on the rear wheel. My buddies make fun of me that I ride my XC hardtail like it's an enduro bike.
great choice i was going to recommend the same set up. I ride 2.20's by i have used Maxxis tires for years with great results and very little flats. I ride the ikon and ardent race. definitely my two favorite tires by them. i've ridden the ardent race rear, and ikon for the last couple of years and it's a great set up. the crossmark II's are another good one and the high roller is a fun one to roll if you aren't looking for a low rolling resistance race tire.
the only flat i have ever gotten with maxxis tires (been riding them for about 10 years) what last summer at the steamboat stinger and that was just due to my laziness and not taking care of my bike. i burped the tire and had ZERO sealant in my tires.
Yeah, this was my first time slashing a tire (never flatted otherwise), but I'm a big Maxxis fan. Considering looking into something beefier up front for GT, since there's not a huge need for low rolling resistance, and would prefer to stay rubber side down in the chunky stuff. Like the look of the Highroller II, Ardent 2.4, and the new Forekaster 2.35.
