The Maxxis Monorail has a radical tread pattern that’s designed to run all-out in dry XC race conditions. The ramped center knobs run in a serpentine wave, providing grip in loose sand and gravel without slowing you down in the straights. Stiff, C-shaped side teeth slash through corners, wide-set middle knobs shed mud, and thin “monorail” bars running lengthwise add lateral stability and reduce knob flex, decreasing rolling resistance while simultaneously increasing traction.

Great XC racing tire in dry conditions

    I've done XC races with the non-UST version of this tire on front. I've only run it with tubes (although I may use it with Stan's this year on my other bike). Mine is lighter (535g) than the weight listed here (585g). It has a fairly large volume (i.e. pretty tall) for a 2.1 width. The knobs are not very aggressive (not tall), so I would classify it more as an XC tire than an all-mountain tire. It has the best grip when you lean your turns, rather than steer them. Tracks pretty straight in sandy conditions. Haven't used it much in muddy/wet conditions, but it did pack up (did not shed the mud well). Only weakness is it seems to slide out easily when I'm turning and then need to brake (easier than my Rocket Ron, for example). Straight line braking is excellent.

    My Review and UST or NOT?

      First, HuckNRoll, please be more clear on whether this is the UST version or non-UST. You have a bullet point under the description that says UST however, your specs has the non-UST weight. This tire in UST is 700g.

      I have been running these tires out here in Colorado (and states nearby) and they are some of the best tires I've ridden in just about all conditions. One issue I've had with a couple (not all I've owned and ridden), is that it seems the Stan's solution can have a bad reaction and I've seen the layers of the rubber separate. You might notice some bubbles form on the middle of these tires - I can only imagine this is a chemical reaction caused by the much needed scoop of Stans.

      To my mtb'n friends in CO (and states close by), I would highly recommend these tires and perhaps trying a different 'anti-flat' solution to guard against the thorns/goatheads and other minor slits in the tire. I'm very surprised I don't see more people running these tires around here.

      Dry Only

        These are not the most durable tires, I shredded a set within a month. They give great feel and work well when it is dry but not remotely suitable for even a little bit of mud.

        the maxxis monorail tire is for front or rear wheel?

        The Maxxis Monorail for for both front and rear. It's also a directional tire, so make sure you check the stamp on the sidewall when installing it.

        what does UST mean?

        what does UST mean?

        I don't know where you see it on this page, but usually it means Universal Standard Tubeless. I'm pretty sure this tire is not a tubeless.

        The Maxxis Monorail comes in both a non-UST version (run tubes inside) and a UST version (run tubeless). From the drop-down menu "select option" above, the UST version is the more expensive option.
