<p>I'll have to get someone else to report on them, because although I'm building them I'm not riding the A23s, I am sticking to tubs (no pun intended) with Major Toms to race. I will get some A23s as I am already sick of adjusting the brakes and I have only swapped wheels out once!</p>
<p> </p>
<p>FWIW, the listed ERD on Velocity's site doesn't match what I measured up.</p>
<p>I am using:</p>
<p>A23 601mm</p>
<p>Major Tom 600 (they list 596 which leaves several threads showing).</p>

<p>I measure mine so the spokes are flush with the nipple screwdriver slot.</p> They are awesome!

<p>In case this helps anyone, I am building up several sets of A23 and Major Tom wheelsets and couldn't find the recommended spoke tension for these rims anywhere.</p>
<p> </p>
<p>Here it is, I got the figures straight from Velocity:</p>
<p>102kgf front</p>
<p>117.4kgf rear (it's the 0.4 that makes all the difference ;-)</p>

it's hard to tell the new bead. i couldn't just by looking at it. it's materials only. there's a few minor differences in printing/imprinting but only hutchinson probably knows the way to tell. I'll see if I can find out.

I assume that they're the new Piranhas, and the sidewalls say Tubeless Ready on them. The beads look like my Hutchinson road tubeless tires. I can pick up the Stan's Cyclocross strip kit locally, but with these wider A23 rims, I was thinking I might need the 29er rim strip kit. I'm not sure how much the strip is supposed to extend up the inner sidewalls. Any ideas?<br />

good advice re: wider rims!<br />
<br />
regarding converting tires - that definitely applies to high pressure road tubeless - a safety hazard for sure as the tire bead on normal tires will blow off at high pressure.<br />
<br />
not so much for low pressure cyclocross though. many (including us) have had <a href="http://www.cxmagazine.com/going-tubeless-cyclocross-tires-racing-recommendations" target="_blank">good luck converting other tires</a>, at our own risk of course.

You might also think about getting the Velocity Major Tom or the HED C2 rims (Bastogne through Flanders). These 23mm wide rims alleviate the problems that others have mentioned with the Shimano specific rims. The Shimano rims are 19mm wide, which creates a lot of pinch at the bottom of the tire. At low pressures, this is why they burp in CX. The lesser pinch of the tire profile on the 23mm wide rims has worked better for us on CX tubeless conversions.<br />

Always use Tubeless specific tires. You can always convert a rim (I've been racing Bontrager Aeolus 6.5 carbon clinchers this season in the USA Crit Series without a problem), but you can't covert a tire.<br />

hey david,<br />
<br />
well, if you want to use your piranhas (assume that they are the older bead) I think you'll need to make the bead tighter. a rubber rim strip that fills the entire rim, or a stan's strip, should be good. not a big fan of velox in that situation - just because the cloth seems to absorb sealant - but i could be wrong about that - maybe it's polyester but I thought there's some cotton in there.<br />

<br />
anyway, hutchinson has a new carbon bead in their cyclocross tires, both the bulldog and the piranha. from what we can tell, it seems to be an improvement. stay tuned for our full review online shortly. note, the profile is "optimized" for road tubeless rims...<br />
<br />
try some type of rubber strip, sealant, and start at 30psi and go down from there. the hand and burp test should be a good proxy unless you have super strong or weak hands. post back what you end up doing and how it works out!

Good info, I wish I'd read this stuff before I built my wheels and bought tires. I have some Piranhas that I was planning to use with Velocity A23 rims. If I use Stans strips, and maybe add an additional layer of Velox or something, to make the beads quite tight, am I likely to be able to run fairly low pressures? I'm 180 lb, so I probably can't go too low without denting the rims, anyway.
