Owens, there's this:

http://www.competitivecyclist.com/frame/2012-civilian-bicycle-co--ramble---2012-10919.html

I don't know about the brand, but the site has really impressed me with it's warranty and returns policies recently. It's legit. Lifetime returns and 3 year warranty on that frame is pretty killer.
Does anybody have experience with Williams wheels? At 1350gr & $570 for climbing wheels seems like a very good deal. http://www.williamscycling.com/Wheel-System-19_p_7.html
Don't do it.  Have a set built with better rims for less.  Those wheels have a low spoke count for very light aluminum rims.  Go with a 24/28 spoke count for wheels that will stay true, won't flex when standing and will descend well.  Spend $130 on some ebay hubs $200 on a pair of Stan's Alpha 340 rims (24/28).  That leaves you with $240 to get spokes, nipples and a build. You will be left with wheels that come in under 1300 grams and cash in your pocket.  The Stan's rims have a wide inside cavity that really increases the footprint of the tire.  They feel like 23mm wide rims.  My training wheels use Alph 340 rims (24/28) with Alchemy hubs.  The hubs are way overkill and cost me close to $600 alone.  I had a very good wheel builder (Ergott wheels).  In fact, you should contact Eric (the wheel builder).  Tell him you want climbing wheels and that your budget is around $500 and you don't mind going cheap on the hubs.  Why not get better wheels, built just for you (your weight & intended purpose in mind) by a local craftsman (Eric is on Long Island)?  Yacks

Oh cool.  Thanks Vlad.  Yeah, I like the CVLN's but they seemed a bit pricey (I've heard they're much better built than the Linus, which a few folks have told me aren't so great for their price, construction speaking).  But on sale, this is pretty dope.  Maybe I'll order one too!
@adam i envisage yours looking something like this:

Anyone know about this?

paired with this?

Seems like a no-brainer way to train; just plug in your program, get your playlist on and train like Rocky IV nemesis Ivan Drago.

Edwin Ortiz has a pair of these on his CAAD10, you should ask his opinion.

Yea, I was gonna comment but I have to agree with Yack. You could definitely get something comparable or better built up for less, my set is an older/cheaper version. I am actually put off by the low weight now that I am like 10 pounds lighter than when I bought them. My rear rim started developing a crack near a spoke nipple and had to have it warrantied. There's only 1 year for the warranty so they are obviously not meant to be very durable.

Also, I noticed in one of my races that the rear wheel would slip out under power, not sure if it has to do with flex, or loss of traction.

A little more research and you'll find that they are just re-branded chinese rims, Mr. Williams is a fine salesman.
The Blanco team uses Vittoria Pit Stop in their tires:

I wonder what kind of dose per tire.  They also probably don't have to worry about the stuff drying out inside, as the tires are trashed before that happens.

Things that make you go hmmm ...
I just noticed my saddle (a Specialized Toupe) is a bit loose where the rails go into the nose.

Is there anything to do to try to fix this / tighten it up ? Or is it a sign that the saddle is on it's way out ?

Just felt the same sensation when powering out of the PP chute... these wheels are so sprint discouraging. but at least now i can put part of the my crash's blame on the wheels right? Yep, totally the wheel's fault... :P
my rear wheel sometimes feels like it's slipping under power, but it's actually just my poor weight distribution moving too far forward and lifting the rear wheel off the ground.  perhaps the same is happening to you?  only happens to me out of the saddle.  should happen less now that i have the proper stem!  thanks, edwin.

possible fit issues? Ive never had a proper fit, but ill try experimenting and see how i can avoid this from happening.

No problem, dude! Enjoy.
i'm about to throw my cross bike together and am only shy one component, a cassette. what's good all around gearing to pair with  46/36 chainrings up front?

also does anyone have recommendations for a cheap(er) home air compressor that kicks out enough pressure to mount tubeless tires?
12-27.

Try husky brand refurbished from home depot.
Was meaning to chase down the "creak" in my bottom bracket but until my rear shifter went all squirmy on me today I just couldn't find the time.

two lessons learned here:

1) having an extra rear der. hanger around is GOLD.  Old one was bent, slapped the new one on and the Dark Knight was shifting as good as new

2) apparently it is possible to CRACK the axel of a bike - see below


I have the derailleur hanger alignment tool. You can always come by.

I've been able to mount tubeless by using a co2 cartridge.  It gets expensive, but works in a pinch.

Thanks for the offer of the "Re-bend-o-tron"  Those things are bendy enough (I find) and once they begin to get squishy it's game over.  I see that you can buy TITANIUM ones (Yaks) but I think they're meant to give first to protect the frame & derailleur themselves, no?

I'm seeing a lot of these around at better supported races these days

Me too...

I had tried that previously to no avail. But I just now got it to work with a lot of soapy water. The fact that for the last month had the tires (Michelin Mud II's) mounted with tubes in them probably helped a lot too in shaping the tires to the rims (Ultegras)
Rick, can I just say how much I love the fact that your assembling your cross bike in May. Cross season in just 4 months! Yeah!
@Rick Perner  If you're not already doing so...please just make sure to wear glasses when you do a heavy shot of CO2 inflation, particularly with a non UST tire.  I have a friend who did some real damage to the bridge of his nose and just missed his eye when the bead exploded while trying to do a tubeless mount with a non UST tire.
Jim Cross has been on my mind. My newest dog walking client is on Cicli Devotion and is always talking it up re cross, and saying how we should go out to ride some lesser known single track etc. Also my GF has a CAADX on order from Ride BK due to arrive 5/31. She is thinking about racing cross too. Lastly, Saturday's crit workshop race to the first corner drill got me thinking about holeshots. (insert sophomoric homoerotic joke here)

I am looking forward to racing cross in September.

@Neil Sorry to hear about your friend. I wasn't wearing eye protection. But will do so going forward.

@Jules The couple of reviews i read re the Craftsman portable inflators said that it was hit or miss for mounting tubeless. It gets props for having a digital pressure scale that measures in PSI or BAR with .1 increments
@Rick - I've ridden my cross bike to Cunningham park in Queens.  Not the best single track (not challenging enough) out there for me, but the closest if you don't have a car.  It's about 10 miles from Astoria.  We can ride there when you get your bike all put together.  The best part of it is, when the local MTB guys see me leave the trail and ride home on the same bike.

ever bend a paper clip?  If you re-bend it multiple times, it gets stiffer and stiffer until it breaks.  Derailleur hangers are no different.

Derailleur hangers are supposed to protect your frame.  Titanium ones would probably be more flexible, but would probably have a lesser likelihood of breaking.
My ti frame uses a chunk of 6/4 ti for it's der. hanger.  It is the same material aliens use for their space crafts...I'm pretty sure you would break machine tools on it...

No word on where @twoyacks got said chunk of alien space metal...

Rotor Cracked Crank update: Rotor emailed the deal (Chad B) who gave me one out of his stock.  New crank is happily back on the Dark Knight.  Sometimes customer service is good :)
