    Frozen Footprints?

    Hi all,

    What's the ideal pressure for refrozen footprints? My first ride on my fatbike was on here, so I didn't get the hit of Fatbike Grin I was anticipating... more of a smirk, and a wince.

    It was tough keeping control since the tires were sliding to the left and right over the sloped footprints. Do I drop the pressure as much as I dare for grip, or keep it high and try to go faster?

    Interested in your experiences, will continue to have my own as the winter goes on. Still love this bike.

    Post holers suck! 20psi probably hurts more if you're able catch them in the act and roll over them. In lieu of that, biggest tire you have at lo psi. Experimentation is required to figure it out. Probably 0-5psi though.

    I figure there's a big learning curve with pressure, so I use my pump often and am always testing things out. Do people carry gauges or just go by feel (I'm used to the latter on my other bikes)?

    I dropped them down so much, I could flatten down to the rim if I bunny hopped on pavement (didn't do that more than once). That seemed better but things were still very, very squirrely.

    I am thinking maybe refrozen footprints with a completely slick ice surface are studs-only territory, maybe?

    I know some people on this forum make it sound like fatbiking on snow is all grins and giggles, but sometimes it just sucks. As a VERY general rule, you're probably better off with lower pressure in the conditions you describe, for traction, control, and comfort. For short sections, where you can see better trail on the other side, I will sometimes power through, but that will wear you out over time. I run a rigid fork, but some people are liking a Bluto up front for postholed trails.

    Low pressure remains the key. I usually run mine low enough I can press then to the rim with my hand, almost.

    "Mostly flat" rolls over all terrain.

    low and slow. Some days it's better to find a different trail.

    Yep. And it takes a ride like that every once in a while for you to appreciate the blue bird rides.
    The swearing up a storm, the I'm cold/wet/overheated, it's getting dark and I should have been home hours ago, why did I go out this far when the conditions were deteriorating, I'm hungry, I should have packed better, tried less PSI, tried more PSI, "this ride would have been cake if I had ___ equipment instead of the ___ I'm running", I need a bail out option.......is there a bail out option?

    Instead of a sign showing who yields to whom, we need a sign showing user groups flipping each other off. Or... we could just see other trail users as kindred spirits who love the outdoors and show some tolerance and courtesy. Ha.... Like that will happen.

    If you were just kidding, sorry... had to vent.

    Luckily there's Type 2 fun. Plenty familiar with that.

    Besides, nobody buys a Pugsley to get KOM's!

    Horses ruined our freshly groomed trails on Saturday. We got 3 foot deep extra large post holes....

    That's why I dont ride groomed trails, unless you count Ma Natures groomers: wind, snow, ice, freeze/thaw cycles, dog teams, moose, and (God bless 'em ) snogos. If you don't own or pay for said groomed trails, deal with it, I say. If you do, then you got some poachers to catch and prosecute.

    Just get on your skinny 26er bike, go ride the frozen postholes for awhile then switch back to the fat bike. They will feel much better.

    Yuuup. Beat me to it:

    Horses to everyone else: My owners are elitist douchebags that own ALL TRAILS. Oh, and, I hope you like my poop.

    Just get a Bucksaw and ride really fast, yell passing and you won't even notice the post holes. No matter what tire pressure you are running.

    This drive me NUTS. Horse owners around here seemingly have no compunction about leaving a giant, 10 pound steaming pile of crap in the middle of a busy MUP and simply walking away. Admittedly, I know nothing about horse riding but why is that tolerated?

    Yes frozen footprints can be annoying when they are pinballing you all over the place, but I cant complain too much as these same hikers/dog walkers are the ones that pack the trails after a large snowfall making the trails rideable again.

    Suspension definitely helps with icy postholed trails. I get that you're exaggerating a bit here, but I'm still going to point out that a trail CAN be postholed so much that nothing helps.

    If the trail really is completely ice then studs are the name of the game. If there are just small bits of ice with firm snow around you can get away with regular fatbike tires.

    Thank you. I was wondering when the studded option would be mentioned.

    Postholed snow is *rougher* in most cases than dry trails. Low tire pressure will only go so far - if you want a smoother/more controlled ride, your next step is suspension. I actually ride an FS fatbike in the winter and spent a lot of time on hardtails in the summer - because due to heavy use, our winter trails are way rougher in many cases. Much more enjoyable with suspension.

    Yup. me too. That's how the OP can stop the slipping and sliding and solve a big part of the problem.
