    Anybody have trouble running crossmark exc 120tpi tubless?

    I see they are pretty light and want to try one on the front to loose some weight. Have the normal crossmark on the rear no troubles but it weighed 630. I'm seeing the exc is in the low 500s

    You can convert the EXC to tubeless. Just make sure you are riding the right kind of trail for that casing. They are fragile.

    I thought about trying one of those up front too, but ended up ordering another one of the 60 tpi versions. I can deal with the little bit of extra weight for $40. Can't remember exactly but my reg version was way under 600.
    Wait,who did he tell you that?....
