36" versus 29" ??

Documented with pics on his site. http://stoiccycles.com/currentframes.html

My bike is the set of pics below

Do you have any better pictures of yours built? The one on that sits is blurry.

I can't take it. Where do you source wheels for those things?

Or unless your frame is my size with a 26.3" TT and longer wheelbase....[SIZE="1"]I hope.[/SIZE]

Unicycle.com Has tires rims and spokes. Under the commuter parts.

Bryan,

A sneak peak of what's coming for mine.

So that makes 5 total bikes that I know of. Who'll be #6?

[Keener]

I had drawn up a truss fork, and it was my plan to build that way. I was talked out of it the day I made the fork. As what I built was faster to build.

I am so stoked to see and hear of peoples projects on the 36" front. My plans are still all over the map for the new one.

Ben thanks for the photo of yours!

[benwitt11]

It should be good. This is one part of a two part project. The second is a lot more outside of the box, and should fix a big "problem" with the big wheels. I'm more excited about that one, and it'll be here soon!

Damn tease! Waiting with baited breath (sushi lunch).

I'm crossing my fingers that you're talking about un-drilled rims, but I doubt it.

My project got stymied on the rim subject since I was trying to do so much of it on with OPP.

[benwitt11]

No such luck on rims. I'm just working on getting the new rims and tires. Those should be good for 4 lbs off my current set up.

The big "problem" will address the handle bar height issue. We're talking as low as 37"s off the ground.

That's interesting.
Warwick was kicking around the idea of connecting the bars to the fork crown (just kicking).

[stoiccycle]

Got my 36er rollin today, so guess that makes #6? didn't get much riding in since it was/is cold, but plan to get some miles in over the weekend, probably will add a little extra braceing around the BB-ST area before powdercoat/paint, but i couldn't want to any longer to see how it rides. there are more pics of the bike, and build process on my site at www.stoiccycles.com Jay

wow....

Bet it kind of feels like you're riding "in" the bike.

[Cloxxki]

So, future 36" bikes may not even have a stem under the top cap? To me it makes all kind of sense. I was going to have that done on "mine" some day.

You guys rock to get this vibe going, and to develop at such an astonishing rate.

Let the ride reports keep on coming!

[benwitt11]

Jay, I thought that that was number 5. It looks great! Is that a riser bar flipped? Could you post some up close pics of the tires and rims? I haven't seen those yet, it's the next part of my project.

[Keener]

Major props on your new build.

I would love any info on the new tire and rim that stoiccycle / Jay? could provide.


If you could find time to measure the tire width

And
How wide is the inside of the new rim and can we get a photo of the new tire so I can see how far the tread wraps around the casing?
How about the tread depth? Is it deeper then the TA? Oh I also would like to know the ERD of the new rim. Hook bead? Is it a good tubeless host?

Dreaming about my second 36” in tucson.

[wadester]

OK, I know that Keener rolled up some custom hubs - IIRC the rear is 185mm? Front is?? I do recall you saying that you were trying to keep the bracing angle of the spoke similar to a smaller wheel.

And what hub widths/types (cassette, freewheel, thru-axle) are the rest of you using - or intending to use?

You can get 150 rear cassette hubs, but 110mm (20mmTA) is the widest front I know of - except maybe the Maverick 24mmTA?

A major issue I see with the Mighty 36er is flex due to longer fork legs, longer stays, and longer spokes. Not a whole lot you can do about that except go beefier - but wider hubs with stiffer axles seems like a good foundation to start with.

[Cloxxki]

If you figure in that bikes have been under development for upwards of a century an a half, I would think that by now we could create longer tubes that perform like slightly smaller ones did back in the old days. Wider hubs should add to lateral stiffness of everything. Should that even be required.

[Davidcopperfield]

I strpngly recomend 165mm tandem hubs trough axle 20mm front and rear. Use not a single less spokes than 36 lean towrds 40 or 48. Make it stronger than lighter, the guy who woul;d be interested in 36er is already a huge dude, therefore heavy, and some pounds more on the wheels will not make any difference.

Ahem....

As a slightly lighter guy interested in this whole concept I'll chime in.

The only reason I've asked about fewer spokes (32 hole rims) is that Industry Nine only makes 32 spoke hubs. The only rims available currently are 36. I was thinking that using I9's aluminum spokes would result in a stiffer wheel. We were looking into 135 front/150 rear, but the sticking point was the spoke number for sure. I can assure you I wasn't the first (or second) to hit I9 up on this.

Kinda pointless now since I don't think I'm ever gonna get mine off the ground.

[stoiccycle]

i will take care of some of the ?'s everyone has asked of me, but will not be able to cover all at this time, since i will have to take some measurements on some and some extra pics.
ERD on rims, 767mm (if i remember right, it's on the unicycle site)

ok, so guess this one is #5, i didn't know it had been counted in already, but was thinking i had only seen 4 others.

yeah, 2" riser bars turned upside down, keeps it setting pretty level/right for me, (i'm only 5'9" or so)

i tried to bead them up tubeless but didn't have any luck, it may be possible, but it's going to take a really big blast of air, and if you ever poped one off the bead, you would be walking for sure.

i haven't ever had any of the old/other tires so i can't really compare to them, but the thread deapth is farly deep, i will measure and post that later, i do know that the tires could still loose a lot of weight, they are heavier than liststed on the unicycle site, wheel/tire weight with tubes and cassette (spelling? i'm a single speeder remember) on rear (no brake rotors) was 10 lbs 5.6 oz rear and 9 lbs 3.5oz on the front, 135 single speed hub on front, and 135 xt on rear, incase i wanted to try it as a single speed, considered wider hub out back, but for the first one, i figured i would see how the 135 works just to keep it simple, for me it's fine, i'm only 140lbs. or so. complete bike is in the 36lbs range, could loose some weight on some of the little parts, but not really any more in the frame/fork.
i took it out and got about 1 hour ride in on some trails today, trails have some open flowing single track, and some tight tree sections, with quick really short climbs (strait out of a near 180* turn), it worked really good, i was expecting to have some problems in a few of the tight sections, but went right threw, made it threw every section clean, which there are a couple that usually get me on my single speed 29er, maybe the slightly lower gear helped on one, but the wheels made all the difference in a failry deap sand section with a slight sand climb at the end.
i kept track of how long it took me for the loop i did, and will ride the same loop on the ss 29er tomarrow, to compare the times, it seems like if you just relax and ride the bike it goes pretty good, if you try and push harder it seems to slow you down some, or atlest you don't go much faster.
so far, it's way more trail worthy than i expected it to be, considering i'm not a big person to start with. well, i think that's all for now, i will get some more wheel/tire measurements tonite or tomarrow. Jay

[Keener]

Jay thanks for the extra info, one more question if I may.
Are you using a 36" tube? My scale is a cheep fish/spring type so I could be off some.
But my wheels are 10# front or rear with big disks and the "heavy" rims and tires with 26" tubes.

[stoiccycle]

i have a 36er tube in the front, and a 29er in the back, 29er tube w/slime was around 5oz. lighter than the 36er tube if i remember right.


hey, found the peice of paper i had some other weights wrote down on when i first got the rims/tire order

rims weights were/are
1086g ---2lb 6.3oz
1074g ---2 5.0 oz

tire weight (only weighed 1 of them, and the scale was bounceing around +/- 20g since i was trying to balace the tire on the scale
1985g 4lb 5.1oz.

36er tube
464g 1lb. 0.4oz.

Jay it came out looking nice!
