IF you had a perfectly smooth rolling hub, then the bike would only really pivot around the hub axle as long as you stay off the brake, but as soon as you start touching the brake it will start to roll around the tyre as well.  . .  .  .


That sounds true . . . but I would add any time you are off the balance point, that will happen.  Rather than talk about manuals, let's look at peg wheelies and hang 5's (or any other flatland peg trick). You are standing on the axle.  I have ridden flatland on 24"s. www.youtube.com/watch?v=CQA2E71iWUE It's harder to get up into the hang 5; once you're fully locked in it's not any different, but any time you make an adjustment, it's slower.

And . . . to get this thread back to 22"s, here's my buddy Vernon on his InDust 2Ton 22".   He's getting a short run of 4 more frames made right now; they're almost done.  Can't wait to ride one.

man, both of you, bunky and jared, are saying good stuff. i still can't quite wrap my head around the 'physics' of it (bunky you're exactly right the "lever" is the same; the contact point with rear tire up to axle is key... so why should circumference of wheel matter??   but somehow it feels like it does??? ) . i've ridden my buddy Vernon's InDust 2Ton 22" bike with a 14"cs http://www.plussizebmx.com/blog/2011/11/7/bike-check-indust-2-ton-22.html and it does not feel as quick as a 20" wheel bike with 14"cs.  yes it's quick, but not thaaaat quick.    i'll have to go out and experiment again on my different bikes tomorrow. jared, you're definitely right, sometimes "locking in" to manuals is more important--(look at bmx race bikes with long cs's for high-speed and over-roller manuals or mtbmx26"s with minimal bb drop and short cs's....) in the meantime:

i added this little triangle in photoshop to illustrate manual balance points for some how-to thread a while back ... i can't quite put my finger on it, but with my experience with bigger wheeled bikes (22, 24, 26), i feel like there's still a 'wheel effect.'



and for big wheel + short mtb chainstay (like 15-15.5) + small bb drop perspective witness this:

Uhm, actually I think that has more to do with bottom bracket height relative to the axel line.  If you have two bikes with the same length cs and same bb height relative to the axels, then it should pull up the same.


you're right that bb height relative axle line does  matter on how quick the front end pulls up. BUT it also matters what wheel diameter. i've experimented with this several times.

see: http://bmxmuseum.com/forums/viewtopic.php?pid=3369360#p3369360

imagine you   put some 16"s on your regular 20" bike, see how it feels. or even,the extreme case, let's say you put a couple of large roller-blade sized wheels in your regular 20" BMX frame in the same dropout spots you normally bolt down the axles.  the bike is going to pull up quicker becuase the pivoting around the tiny roller blade wheel's axle (3" diameter) is going to be very quick. if you were trying to manual on those tiny 3" diameter wheels, you would have to do really quick adjustments.... does that make sense?

Wow, I feel like 13.75 is too short on my 20 inch, so I run my back end at 14.  I can't imagine what 13.5 would feel like with bigger tires.


from having different bikes to compare, my impression is that the wheel size matters as to how "quick" the front end pulls up, even if the cs lengths are the same.   like, for example, i have a Liquid Feedback 24"-wheel bike with a 14.25"cs; I also have a 20" with a 14.25"cs (a mid-school Homeless Mack). Despite the cs's being the same, the 20" still pulls up a LOT quicker. if you think about the axle as a pivot point, a smaller diameter wheel will react quicker with other things being equal. on the flipside imagine putting a 16" wheel on your regular 20". even if you put the axle in the same place, the front end will pull up quicker....     so . . . a 22" wheel, but with a shorter cs, will actually balance out.....

Saw a picture on my buddy from Iowa's facebook page.  He has a custom made Standard 22" just made.  His looks pretty dope.  And his geo/set up (based just on looks) seems to be something I would be into more than CMC's 22".  CMC likes taller bars than I do.  I actually just put the 7 1/4" bars back on my Model C.


yo B, u should check out Vernon's 22 some time as well!

apparently, this was a recent e-mail response from S&M regarding 22" wheels:

"We are working on complete wheels, tubes and tires and should have them in 90-120 days from now but I can get you a more accurate date in about 30 days if you want to e-mail me again then."

G, i have a ton of respect for you, but since you are kinda quenching the stoke here, i feel compelled to respond.


Quote from: G;3506005
Hey, I have never tried them myself, just going off the feedback we got from legendary bike riders who tried the size and liked it but couldn't get the performance they wanted from the tyres so asked us if we were planning on doing them.  


"Legendary" riders liking the size . . . seems like evidence enough of a good idea. Not to mention the regular riders/diggers like me and my friends in Texas and guys at PA and NY trails, and of course the riders in England who started this.   And . . . you really do need to try a 22".

Quote from: G;3506005

I thought my input might be constructive but I guess not...


Normally your input is very constructive, but this time it was simply "we looked at this, we decided not to do it, and here are the reasons it's a bad BUSINESS idea, (but apparently is a good RIDING idea) . . . .

Quote from: G;3506005

I am open to new sizes etc, I love my 24" and would happily try this size too, but when we look at the practicalities of it, the tyres are a major hurdle, much more so than doing 29" was for MTBers. If there was a common bead the tyres could share with road or mtbs or something then it would be a lot easier... The 24" tyres we do now are already a bit of a headache from our point of view.


"Major hurdle" and "practicalities" are relative concepts.  Anything bike-related can get made, with high quality, in Taiwan/China these days.  It just takes someone with some money who wants to get it done.  This has nothing to do with engineering/design/fabrication hurdles. It's just money.  One respected BMX/MTB tire company I talked to said they could do 500 tires for $10,000.  In the scheme of things, $10K ain't much.  It doesn't have to be huge to work.  I also had another BMX/MTB tire company tell me they weren't interested because they'd hate to have to distribute 22" tires to every bike shop in north america.  Another straw man. Flatlanders don't get to find their parts in local bike shops, but it doesn't stop them from ordering through the web.

And, in a sense, the "hurdle" has already been jumped.  Faction's first tire wasn't that great, but they followed up with a second one which is awesome. And here it is. My buddy Vernon's been riding them hard for a while with no problems.




Quote from: G;3506005


Stuff like this needs to be top down. Top riders try it and like it, so it trickles down and THEN you get cheap bikes using it. This is what 29" has done. Hard to see how it could work the other way.
Local shredder sees beginner kid with department store bike on 22" and thinks, hey I will give that a go, local shredder goes to bigger comp and pro riders see it...??? Seems unlikely..



Hmmm. Top down. . . . This is a little perplexing, so correct me if I'm misunderstanding you.  But, a lot of the early innovations/improvements/new-directions in BMX were actually "bottom up"?  Back when big companies were out of touch with what riders were doing in the late 80's, it was young riders with little capital, like Mat Hoffman, Chris Moeller, Rick Moliterno & Kurt Schmidt, who were pushing BMX from the bottom up.   As for 22"s and pros, I currently don't see that as a function of pro riders not liking the idea. You already said that legendary riders DO like the idea. Then it is more of a function of the bmx BUSINESS not getting together around a conference table (or a casino table in Vegas at Interbike?) and 'deciding' to agree on the next trend.  Frankly, I will always care more about good riding ideas and bike ideas, more than good 'business' ideas.  None of us should even be in the bmx biz if it was all about making cash.  Cue FUGAZI song here.

Thread is nearly 3 years old now and has reached 4 pages in that time on a super nerdy site like this... not exactly a huge response...



Yeah, I keep this thread going on purpose, because it's a solid concept. Just like the other more complete thread here: http://www.ridemonkey.com/forums/f61/22-inches-love-feels-just-right-237841/.
If you're correct that a top down approach is needed for any idea to become successful, then you'd have to also agree that the BMX industry has largely cold-shouldered this idea . . . then it's a little odd to also criticize lack of "bottom up" support for an idea that the bmx industry has given zero support to.  (Although, that's changing, with S&M, Solid, Standard, and STOUT all making custom 22" stuff right now.)

Quote from: G;3506005

Sorry to be negative, as I say, I would love to try it, and I would ideally love to be able to build half a dozen bikes up with 19", 20", 21", 22", 23" and 24" wheels (or even more intermediate sizes) and try them all,


Classic straw man argument. No one is saying there should be increments for every inch of wheel diameter.  That's an easy argument to shoot down.  

The real issue is that the gap between 20" and 24" is massive.  And it's ludicrous that adult BMX'ers have had to choose between tiny 20" wheels or kinda-cumbersome 24"s for so long now.  I do NOT think 22"s are a genius invention, they're not even an invention. They're just a necessary adjustment that feel instantly comfortable to ride.   Every other 2" increment bmx size is widely supported EXCEPT for 22". There are 10", 12", 14", 16", 18", 20", 24", 26", 29" and you might also include 700c with the nex fixie freestyle guys.  I frankly wonder how many 18" wheel bikes Hoffman sells. Most parents with a little kid want to pay less than $100 at a big box store on a bike that size.  

Quote from: G;3506005

 but the reality of the industry is that BMX is small and relatively unprofitable branch (compared to "adult" bikes) and this is a small segment of that small market, its hard to see how we could ever get the tyre manufacturers (who need huge numbers) excited about it... "hey on a few years we might get 10% of 5% of your sales, so that is half a percent of what you make?!?!?!"


Somehow, the original dreamers and innovators in BMX, were not dissuaded from pursuing their ideas. 14mm axles, freecoasters, Potts mod, heat treated tubing and axles, pegs that didn't strip out, front-brake 990's, re-designed gyros . . . so many ideas in BMX were just ideas that some riders had.  They often started out as rigged homemade modifications.  Well, right now, riders are getting 22"s homemade/custom-made.  

I don't claim to have all the answers to the tire question, but I will continue to pursue them.  

Even though FACTION are not part of the inner clique of the BMX industry . . . I respect what they've done (put their personal money behind a good idea) way more than some of the current BMX companies who just offer 20 colors of exactly the same part that every other BMX company is making.

Once again, I do highly respect you and your opinions, so this is not meant as a personal attack.

Yeah probably, it doesn't look so bad now I look back at it anyway. Seriously interested in these bikes when the new model comes out but the only thing putting me off is the tyre availability situation at the minute. Hopefully when I can actually afford one that'll be sorted, and I'll be able to find one to demo in the uk.


Apparently, the tire thing is starting to work itself out nicely, at least in the UK.

I found several tire options on eBay UK:

One of the reasons the tires are more available might be because Toys R Us in the UK and other department stores sell a cheapo kids bmx with 22" wheels. I had never heard of that and just stumbled across it the other day.  Crazy, huh.

well i dunno what the seat tube length is--i'll have to ask the dude--but it MIGHT just be that the standover looks low because of the taller wheels/tires. but it might actually be the same as a 20" (comparing bb location to top tube location).   just a thought.
