    Fork isn't "squishy"...

    Hey all,

    I had a quick question. I went out today on a ride, and the fork on my bike is not very squishy at all. This is new. Why would this happen?

    What fork? Coil or air? Service history? Is it really cold outside at the moment (some forks can stiffen up in very cold weather)?

    A bit more info would really help if you want some answers

    It's got a coil spring. I've had the bike with the fork since September, and it was brand new. I've done some light singletrack riding and have never had it serviced, as I've never had any indication to do so.

    It's a suntour XCT 100. It has a lockout and preload adjuster (though I'm not sure how effective that bit really is).

    I imagine it's the cold, then. It's about 20 degrees Fahrenheit where I'm at and there's snow on the ground. I just deflated my tires a bit and hit the trail. It went pretty well, except that afterwards I noticed the fork wasn't so bouncy as it had been.

    You know that oil, like many other fluids, experiences changes in viscosity due to temperature, right?

    I hate to be a smart ass, but this is a pretty simple "Ah ha!" moment.

    Nobody who has ever said that actually hates to be a smart ass. I encourage smartassery, but c'mon, be honest about it.

    I really wasn't sure just how much to expect it to not work. But I suppose, then, that a combination of cold and sub-par fork is good enough to make it not very bouncy at all. I'm sure better forks with different oil, etc. will work considerably better at low temperatures.

    If you change the oil in the damper to a lower viscosity then the fork will work better at low temps.

    Here's some service info. I think your fork has grease not oil. Switching the grease to a synthetic lube or gear lube may help.

    You also qualify for the Raidon air fork $200 upgrade from Nick at Suntour.

    Don't spend money on this fork. If you can swap the fluids yourself, that wouldn't be a bad experiment.

    Yeah, I wasn't going to put any money into this fork at all, except to buy grease/oil. I will actually probably replace it with a rigid fork whenever it dies on me.

    What's a good rigid fork to swap out with? I think a rigid fork by Salsa or Surly would be a 29er fork I would consider putting on my bike. Concerns with putting any of those on a Fuji Nevada?

    Ha! Well... maybe it is after all. It's just a suspended mimic that's really a rigid fork.

    The first time I rode a rigid mountain bike, I was shocked at how well it tracked. I think better than a hardtail with a cheap suspension fork.

    It ran out of squish and needs more put in.

    My Suntour XCM fork felt like complete crap.. mainly because im 6'3 225 and the for has no plushness to it. I now have a Reba dual air fork on there and it literally transforms the bike.. for 200-300 bucks, you would be foolish not to think about upgrading to a good rockshox air fork

    Jayem:

    I now realize how obvious this was! I'll get more squish at the bike store tomorrow. They always have squish.

    eb1888:

    Those were great. Thanks a bunch.

    Jams_805:

    I'm 5'10" and about 138 pounds, so I my weight shouldn't be stressing this fork too much, but I'm not going to count it out. That said, I will consider upgrading, in time. Just gotta save money, and I'm leaning towards rigid because of less maintenance.

    The Suntoiur Raidon has a sealed damping system- no oil changes. This means very little maintenance. The fork is 4.5lbs. about 2lbs. less than your current fork.
