22 inches
Love Machine:
I can ride a 21.25 with out being to uncomfortable but, prefer 21.5.
When the time comes I'll probably go with S&M since I can some what customize it.
Also waiting if the put the 22 ATF the custom frames.
Would the 69 Seat tube be that noticeable?
I sent Faction an email a little bit ago.
How much better is the 22 on the knees from hard landings?
milhous:
brobmx on Ebay has (or did have) the Faction tires for sale in the USA.
EDIT- Nevermind, looks like he might be sold out of them.........

I haven't really focused on the hard landings angle... but I guess from a physics standpoint, a tire of the same width is actually holding more air due to being bigger, and a larger rim with a slightly mellower curve is going to absorb an impact more than a smaller diameter one. I know that 24" BMX's do feel smoother to drop off to flat landings (although I kinda hate flat landings these days--always looking for a grass embankment or true dirt landing).
Over on bmxmuseum, tecnic1 posted up his InDust proto next to a Holmes 22. The InDust proto he has was a single frame with a higher bb and shorter back end that was a proto for street/park bike. The InDust 2ton is the trail frame that I have that has a medium height bb (21.8"tt, 12.25"bb and 14.25"cs--where I have my axle now, not slammed but is close the front). Talk to Vernon at InDust if you are interested in one of those, or a even possibly a different version. We have been talking about doing another higher-bb park/street frame. I have never had the opportunity to compare the Holmes up close, but my impression is that the more laid-back seat tube angle actually makes the 22"tt Holmes a tad shorter than the 2ton when you compare "cockpit room" (or front-center, i.e. bb to front axle).

As CMC pointed out there will be a factor related to the tyre. For a given width and pressure a smaller wheel is actually less stiff than a bigger one, so a smaller wheel would be easier on the knees. But in reality you can usually run a bigger wheel at a slightly lower pressure and get the same kind of feel and rolling resistance so that probably puts it back to the big wheel (but it will be marginal).
Another more significant factor will be spoke length. If the spokes are all the same diameter, then the longer spokes of a bigger wheel will be less stiff in proportion to the length. So a 200mm spoke will be half as stiff as a 100mm spoke (ignoring minor factors due to bends etc). But the spoke is not the whole story, the bigger rim will sit nearer to flat so this will make it seem a little less stiff too. You will also have longer fork legs, which will be less stiff than short ones.
It will be hard to quantify with all these factors and all the possible different ways you could land, but since you already tried both 20" and 24" bikes I would just say it will feel about half way between those two ::)

22" wheels are better. Period.
