My 4K Custom Frame

[Krashin'Kenny]

No, it didn't cost $4K. I went digging through the scrap pile again and decided to build myself another frame. Here it is :
Krashin' Kenny's Kustom Koker

[Krashin'Kenny]

I filet-brazed the bearing holders for a cleaner look

[Krashin'Kenny]

And the complete unicycle

I almost forgot to show how the crown looks as though it was made specifically for the Coker tire

Oh! That does look kustom. Nice.

Are you using a standard width hub or one of the super wide hubs?

Very nice Kenny! Quite a tranformation from the way I saw it last weekend. If they ever have a Junkyard Wars episode where they have to build a unicycle, you da man for the job!

Thanks guys

John, it has the standard width hub on a stock Coker wheelset

Scott, you can borrow my old frame to convert that 36" UW if you'd like

I may take you up on that as temporary until I have time to build a frame. Thanks. I have about decided the frame/seat thingy is necessary for distance riding.

Nice indeed. Seems like a good way to save some money while having a good time in the garage. Did you ovalize the tubes yourself?

Cool Color Coker!

Most Cokers are black & white. Nice to see some color on one. Do you get any tire rub? Most frames flex at least a little, and the bigger the wheel gets, the more it can move from side to side. Looks like a great fit in that crown, but I'd be worried about a little rub when you pedal hard.

Another very nice frame Kenny. What was the final cost of the parts for the frame? Have you thought about using heavier duty bearing housings like the 2004 KH or other machined housing?

Yes I did ovalize the tubes myself using a 10-ton press and a couple of thick steel plates. It is definately the most cost effective way to get a custom frame, I've got about $18 in it

John,

There's a little over 3/8" clearance between the tire and the sides of the crown. I've only ridden it aroud the shop, but took a couple of real sharp turns without it rubbing. If it does ever rub, I can easily remove some of the aluminum from the crown for more clearance.

You give me inspiration to make something similar for a 29er. I guess that crown (aluminum is it?) comes from a suspended mtb fork. Are the tubes welded to the crown?

The crown is indeed from an old MTB suspension fork and is made of aluminum. If you do decide to make one of these, there are a few things to consider. I've always used crowns that had "1 inch" stanchion tubes on the fork legs. The forks that use larger diameter tubes usually have a wider gap and will be too wide to properly fit the unicycle hub and may cause "knee interference" also.
Another consideration is the diameter of the steerer tube, which will become the seat tube. This frame was made from a fork that had a 1 1/8" steerer tube and I had to insert (braze) a shim to fit the standard unicycle seatpost (22.2 mm). The crown that I used on my MUni, however, had a 1" steerer tube and the seatpost fit inside perfectly.
Feel free to pm me if you need any more info.
