    Hanging a Bike Upside Down

    I recently bought a Giant XTC 29er 1 and I am trying to figure out a way to store the bike. One of the options is for me to hang it upside down from two hooks on the ceiling but I am afraid of hurting some of the components. The parts I am worried about are the Hydraulic Brakes (Shimano m505) and the front fork (FOX 32 F29 RL-100). I have searched around but I cannot seem to find any consensus on whether or not it would hurt the bike. The detail spec of the bike are here : http://www.giant-bicycles.com/en-us/...er/7366/44091/

    Thanks, Any help would be greatly appreciated.

    I'm 99.9% sure that it won't cause any issues with your bike. Bikes don't stand on their own, so parts need to stand up to falling over, tipping over, and just general lack of static stability. If you're really worried about it, get yourself a Bike Hoist: http://www.nextag.com/bike-hoist/stores-html

    If there's any air in the fluid reservoirs, inverting them may allow the air to get into the master cylinder and/or brake lines on some designs. I advise keeping the rubber side down with hydraulics as much as practical.

    It won't hurt the fork to be inverted, however.

    Hang it!!

    Your brakes have a rubber diaphram that makes it a sealed system and air cannot enter the lines even if the bike is inverted. If there is air under the diaphram the resevoir has been improperly filled.

    There will be some transfer of hydraulic fluid between resevoirs in the fork, but pumping the fork several times once the bike has been righted will bring everything back to where it should be.

    There`s a diaphram in the resevoir to keep air out of the hydraulic system so inverting it does nothing.

    There will be some hydraulic fluid transfer between chambers in the fork but pumping it a few times before the initial ride will bring everything back to normal.

    It won't do any damage. The stress from hanging is nothing compared to the stress from riding that the bike is able to handle just fine.

    1. Hang 'er up.
    2. Strap your brain bucket to the saddle.
    3. Place 3-4 clothers hangers on the wheels. Hang some clothes up.
    4. Turn your bottle cages around and keep a couple of beers in 'em.
    5. Hang wash cloths on the bars to dry.
    6. Hang the bath towel on the downtube to dry.
    7. Use the pedals as toiletries racks.

    Empty your water bottles first, then hang it and don't sweat. Unless the hooks break free and the bike falls nothing will happen.

    Worst case is that if you don't ride for a while the dust will be on the bottom.

    I've hung all my bike for years with no ill effects. If you have a problem with your hyd discs as a result, your system is not correct and you were going to have a problem anyway. You just discovered it at home rather than on the trail. It is a closed system and any leaks can lead to a really bad day.

    There is one advantage to hanging the bike upright by the top tube or by the bars and saddle, however you can arrange your hooks. The advantage is you can do maintenance on the bike as if it were on a flimsy repair stand. You can to do drivetrain adjustments, chain lubing etc., since you can turn the cranks by hand and the wheels are free to rotate.

    I guess you're much taller than I am if you can work on your bike while it's hung from the ceiling. But I guess I could go out and buy a stepladder.

    Often the diaphragms have pleats in them which makes it nearly impossible to avoid trapping at least a few air bubbles under it when closing things up. It's not a case of improperly installing or filling the reservoir either just reality.

    Even so I'd say go ahead and hang it. Just don't pull the brake levers while it's upside down. And if it turns out that you do trap some air in the lever's piston chamber of your a few pumps of the lever once back upright SHOULD see it come back out. If this happens and you find it annoying then re-evaluate about hanging the bike upside down.

    My garage ceiling is a pretty standard height and so am I at 5' 9". I have the hooks screwed into the ends of short lengths of 2x2's and the 2x2's screwed vertically to a board that spans a couple of rafters. The bike hangs with the crank about shoulder level and is easy to work on and to take down for use.
