    Hello everyone,

    In my experience with BC wheels, trying out different riding styles,
    and different techniques of slowing and stopping, So far a hefty leg
    wrap has worked the best. However, wraps have become an insufficient
    way of slowing/stoping.

    When riding trails or even just a steep paved hill, a wrap will only
    slow you to a certain extent. Meaning you have to pick hills that have
    a flat section, or an uphill at the end. Who wants that? I think its
    time BC's have a good way of stopping. A lot of people have said things
    like "BC's were meant to coast," or "static stuff is stupid on things
    that were meant to coast."
    And I agree, but when you are riding something that has the potential
    to go as fast as a bike on a downhill, I think a good way to stop would
    be a nice addition to the BC.

    Jeff groves had an idea to mount plastic strip, possibly lexan piece to
    the bolt/plate, and have it go up to the height of the tire. Being
    flexible, you could push this piece into the tire with the same leg
    motion as you would slow with a leg wrap, Yet with a plastic strip, you
    wouldn't get that annoying vibration that travels through your leg with
    a wrap. Or the daily trips to your nearest drug store for a new pair of
    ace wraps because your old pair vaporized when you tried to ride down a
    trail.

    I had the idea to mount a disc brake setup to a wheel, and have the
    brake caliper mounted onto the plate. Though now I am questioning how
    well this will work, due to the fact that the plate will have a
    tremendous want to flip over while your standing on them. Also other
    problems such as how to actuate the brake, Brake housing getting cought
    in the tire and the over all price of the setup have made me have
    second thoughts about the plan.

    Spencer had the idea to make a wrap with a very durrable, thick
    material, maybe with a rough/abrasive side to slow the wheel more than
    the normal smooth surface of an ace wrap or neoprene wrap.

    All in all, these ideas seem like they could work, but then again maybe
    not.

    The purpose of this thread is just to brainstorm ideas about a
    ffunctional brake on a bc. A lot of the time people have crazy ideas
    about bcs, some just werid, some possible, and some just flat out
    impossible.
    But sometimes people strike gold with an idea, and thats what im hoping
    for. So let the ideas fly people.
    Post drawings or pics, or even just a disctription of a idea into a
    brake design. I need a way to stop my bc!

    Later yal,

    i don't know if this is still a bc wheel. I set out to solve this
    problem a while ago, and came up with welding dropped pegs into a bmx
    fork. this allowed me to use the stock bmx brake mounts, i mounted a
    handle to the steer tube. The extra leverage from the handle allowed
    for as much braking power as i can controll, which was never very much
    because i never figured out how to use it effectively.

    having the handle also allowed me to give a good strong skate push
    without the wheel hitting my leg. i could also drag one foot on the
    ground to slow down.

    Here's a pic of brian holding it

    P.S. It's harder to ride than it looks.

    I've got this retarded idea but this is brainstorming, right?

    How about you get a good pair of gloves, put some rubber(or whatever)
    material on the inside and stop the wheel with your hand.

    I've never even touched a B.C. wheel(I want to though), so I don't know
    if this will work.

    With the idea of having a piece of something to touch the tyre, maybe
    you could mount rim brake pads on it somehow, so that it would push
    against the rim instead, might give you more brake power and control.

    How about an off centre axle and a disc brake. ie. instead of the
    plates hanging straight down from the axle, the attachment point on the
    plates is further towards the front of the plate.

    It'd mean that the plates would hang pointing straight down when you
    weren't on them which might make it harder to mount and jump off, but
    would give you more leverage for braking and make flipping less likely
    right?

    If you had pretty long plates, you could try and learn to move your
    feet backwards a little bit when braking to counteract the flipping
    force?

    Or alternatively, have an arch just over the wheel, which you could
    mount any old brake on, and then have the brake lever attached to a
    piece of strong wire (as well as the normal brake cable) made just the
    right length so that when you were braking you'd hold the wire taut, so
    your whole weight would be against it flipping.

    You could maybe even simplify this by not having a lever, just having a
    bit of thick wire, attached through a cable guide on the arch to a v or
    cantilever brake, with a handle on the other end, and to brake you'd
    pull hard on this, stabilising the plates with your body weight in the
    process. The problem with that might be that the tendency to flip would
    mean that braking would lead to harder braking and it wouldn't be
    controllable.

    i have came up with two ideas in the past. One is just the front of a
    bike like brian had. The second one was a nicer way. It is hart to
    explain but the mount it wlded to the be and you hold the brake like
    you would on a mountian board

    You can make it that if you push the plates inwards really hard with
    your ankles it sets a brake going.

    have a metal pole with you, and then just jam it in the spokes and it
    will catch on the back of your legs, and i promise you will stop real
    fast...
    jk jk.
    i like the idea of a piece of a brake activated by your let, so that
    you use the same motion you would normally use for the ace bandage to
    stop. what about an elongated brake lever that you push in to the rim.
    be sure to angle the brake pad or else you won't have as much control
    over stopping power.

    edit:maybe on the brake lever thing you could have a little pad that
    your leg pushes against to stop the bc.

    take a frame with vbrake or magura mounts and weld it to your plates and
    find a piece of bar to fit the brake lever on andjust hold it in your
    hand thats what works for my mountain board

    Interesting ideas...Something to point out to people who dont BC, the
    ability to move your arms freely and in the full range of motion is
    something you want on a BC. So a fixed lever on a section of tubing
    wouldn't be desirable.

    When it comes to fighting the plates want to flip over, I thought maybe
    a piece of tubing attached to the axle/plate, coming up to your mid
    calf, and having a padded, curved piece of plastic, metal, carbon ect
    on the back of your calf. When the braking force is applied, this will
    put pressure on your calf, and the rider can lean back into that, to
    fight the torque of the brake.

    I never really though about a v brake, it would be a good idea, because
    the fork or "Arch" could also be the peice of tubing i described with
    the calf pad on it. Also you wouldn't need a specail disc hub with
    mounts.

    Keep the ides going people, I already wish i had made this thread
    before i ordered a disc bc.

    Some time trials bikes used to (do any still?) have no brakes (designed
    for lightness, and nothing else, I guess), so riders would use an
    armoured glove to slow down the front wheel (guess they didn't need to
    stop quickly on a track!).

    Not sure it'd be that easy to use on a BC, but the general concept
    certainly makes some sense to me.

    since you don't want to restrict arm movement, you could have the v
    brake be pressed to the rim by your legs, like when you like clench
    your legs or something.

    or make each side of the brake seperate so that each side is pressed
    individually on the brake, cause you dont need that thing on the top if
    your not using a cable, right?

    Well i was thinking about a hand brake, having the housing/cable run up
    into a grip with a lever.

    what about a bc plate system, if you lean too far back on the plates it
    automatically pulls the brake a little?

    The brake isnt just to save you from a fall, but to just do hills
    slower.

    but on a hill you would have to lean back a little to maintain balance
    because of the slope, but it would be a problem to attach it.

    True, But remember your ankle isnt always locked, you can tilt the
    plate back with your feet, and still stay in the same position with
    your body.
