Was there not also a mad 4 one hub with internal disc brake mounts
I may have dreamed this

The mad 4 one hubs seem to be available in 36 and 32 holes

But again yes would be standard width and not fit an Oregon

No, the Knard will not fit in a KH29.

Yes, there is only two choices for now: the Mad4One and the Nimbus.

None of them feature the disk mounted on the hub (but heard mad4one was testing a prototype). And both are 100mm bearing-to-bearing.


@BrickMan: According to previous reports from rawcyclist and davidp, none of the recent KH29 frame has the clearance and the 2007 version barely has...

Either go for a 36 frame or look for a more generous 29 frame

The 2007 KH29 frame seems to be so close as to not be reliable as Bryce said his wouldn't fit:

Nice write up. I like the summary. Tho, I'm in a bit of a quandry now. This is the 29er tire I've always wanted and I've been waiting for it for what seems like months, but the frame choices are so limited. I don't think the Oracle has rim brake mounts and I do have a thing for the Maggies on all my unicycles. . . .so . . . . .I sent an e-mail to Triton to ask about spending a lot of money on a frame made from Russian Ti.

Please excuse this minor thread-jack: Anyone know which of the Triton standard 29er compatible frames will fit the 29er knard tire? Will it have to be a custom frame?? . . . or maybe all Tritons are semi-custom anyway??
Any experience out there with this?
Bryce

Bryce
Triton does sell some standard/non-custom frames: http://ridetriton.com/products/en/Frame/

I'm pretty sure the standard Triton 26-29 frame will not fit a Knard. You can see in this photo of SinisterJay's frame that it doesn't have a ton of extra clearance with a Dissent 2.5.

So yes, I think you'll need a custom frame. If you don't need the frame to work with a 26x4 tire then it might be as simple as ordering a 26-29 with a taller crown.

Bryce, I have a Triton Tripple Muni frame with the crown raised 25mm since I wanted to be able to ride a 26x4, my 29x3 Frankentire and my 32" homebrew wheel. Dmitry sent me a pre-made triple frame to see if it would work but the crown was too low for the fat 29 (I hadn't made the 32 yet)

The regular 29" frame is designed for a "snug fit" so you can probably rule that one out.

I would shoot Dmitry an e-mail, he might have what you need laying around but you are probably going to have to go semi-custom which means getting in line and waiting for approximately one schlumpf spa day for your frame.

In the mean time you can always add some frame extenders (what I did while I waited for my frame):

Now there's a good ghetto solution. That's better than my shim idea. I don't really want to buy a new frame, so I may have to try that. $12 for a set of frame brackets from UDC, 2 bolts and a few washers.

Hey, I just thought of something...if the Oracle frame is redesigned to fit a Knard, you don't have to change hubs to the Oracle disc hub, instead you could run a Spirit crank and use the D Brake on the other side.

It is a shame the KH frames are not just a smidgen taller and wider, hopefully they'll get a redesign in the near future.

Does anyone have a inside dimension (between the legs) and a crown height (spindle center to underside of seat tube) for a QuAx 29, Drak, Nimbus II 29, etc...? Maybe there's a frame out there that'll work.

@ Bryce, you could buy a Nimbus steel frame and remodel it for far less (and far faster) than you could get a Ti frame made. Geez, for the price of a Triton you could buy an Impulse 29 or an Oregon!

Oh, and one more thing, the 27tpi is significantly taller and wider than the 120tpi, about 5mm in each direction. After a few rides I just measured 75mm outside knob to outside knob! It barely fits in my Thule roof rack tray

Today, on the last leg of my ride I bumped the pressure to 17psi on the 27tpi Knard and it was quite firm, felt like the 120tpi at 20-22 psi.

So simple, but something I'd never have come up with. How do you think something like that would hold up over time?

Seems as long as you have the frame width, the world is your oyster.

Check your frame width first, the Knard is wider than a 3" Duro by 5mm (75mm vs 70mm), but in looking at Nimbus 24" muni there appears to 1/2" on either side, so you'll need to get the tire tread in the sweat spot, but otherwise it'll work. Too bad there isn't a purpose built frame extender...but wait, I believe Bryce has a Tig welder, oh Bryce...

+1.

How does this custom extension technique hold when doing some muni riding (rought terrain, drops...) ?

But for sure, it is an interesting idea that could be sweet for a certain number of existing frame if it was just off-the-shelf accessory
