I just picked up this IH so I can build my 1st DH bike and expand beyond my XC boundaries.

The bike has the stock floating brake. Needing wheels I picked up a set of Outlaws with the 150mm backspacing . It seems that I cant use these wheels with the floating brake??? and Im not sure what my options are.....

There appears to be about half the needed space for the floating brake to fit...maybe 7mm? With the wheel and no floating brake I would need to put spacers on the wheel or something?

Any help would be appreciated....

I have a Kumicho as well and have never heard of the floating brake, can you post pictures? If it does have the floating brake I don't see why the wheels wouldn't work if they are the correct spacing etc.

This is not my bike but it is the exact same floating brake kit. Im wondering if the stock wheel was dished or had a special hub.

If you are going to use floating rear brake mount, you'll need a 135x12 rear hub. However, I didn't notice much difference without it and it's very loud too :)

Brake really hard into a very rutty/blown out section of trail and just try to keep your feet on the pedals. It's hard.

Really.... DOH!

What doesnt make sense is that even with a 150 wheel it seems that there is still a extra space between the dropouts but not enough for the brake mount....

How do I take up this slack?

I remember there was some extra space, but after tightening the rear axle bolts everything was okay. That was a really nice frame, but 5th element was crap and I was lucky to get the frame alone, without that crappy manitou stance triple :)

take the floating brake thing off and sell it, get an 8" adapter and mount your brake the way it was meant to be.

I'm thinking maybe it is supposed to be a 135mm with the floating brake... It doesnt look like the 150mm sits centered between the dropouts??? I need to double check it tommorrow.

The Kumicho was originally built with a 135mm rear wheel and floating brake mount.
When Iron Horse got rid of the floater (in 06 I believe) they switched to a 150mm rear wheel, but did not change the jig for the rear triangle. You'll see the offset if you stand at the back of the bike and look towards the front.

What this means is you either have to run a 135mm rear with floater, or use your 150mm rear with no floater and have a shop dish the wheel apx. 6-7mm towards the drive side. The spokes on that side will be nearly flat in the vertical plane. I ran this setup without problems.

The rear end does spread wider than150 by a few mm when a wheel is absent. No worries there. They're all like that. Just snug it down. :thumbsup:

Personally, I'd lose the floater. Less weight and less chance of "floater noise". That's why IH got rid of it. That and most riders couldn't feel a difference. A shop should charge about $20-30 to re-dish the wheel.

Best of luck. The Kumicho is an awesome bike!

Just got an 05 with floating disk removed, and a cone spacer on 135 hubs, but when I tighten the 12mm bolt all the way, I can still have a little play (can move spacer in/out by maybe 1mm or less), which makes the rear flexy. I too was surprised to see the rear that much wider than 150mm - doesn't seem like clamping down the arms and putting that much pressure would be a good thing - good way to brake the rear arms over time IMO....

Went to hardware store and bought a regular stainless steel washer, put it on the inside on the drive side (outside to shorten my maybe too long bolt would still put too much pressure on the arms, while putting on brake side made them not align without enough room to adjust calipers) and that took care of the flex and needing that much slamp down.
Hopefully that did the trick...
