8.75"x2.75" (222x70mm) The mounting hardware is 22mm wide, with an 8mm through hole.
When we were developing the new V10, we tried a couple of versions with longer shocks, as that is what the hypemeisters are hyping these days. After riding both versions, we came to some conclusions:
1) The 9.5" shock and required longer spring added over half a pound to our frame. Trying to develop a light weight race frame requires a lot of gram counting, and a half pound is huge.
2) It didn't ride any differently. We did blind back-back testing on two prototypes (the only difference was shock stroke, we made a custom frame and link) with a bunch of people, and nobody could identify a difference.
3) The extra " of shock stroke really isn't that much. Instead of using a 500# spring, you would probably use a 450. Not a big difference for an extra half pound. A 3.5" stroke didn't work with the VPP linkage to get the shock rate curve that we wanted, isn't available from a variety of sources, AND weighs a ton.
4) Our pro race team has been racing V10s since 2001. The frame has always had 10 inches of travel with a 2.75" stroke shock. They don't have problems with shocks, nor could we find any evidence from our personal experience or warranty records to back up claims that lower leverage/longer stroke is better for the shock.
We tried to like it, because we've been asked about this, uh, frequently. But in the end we decided that measurable performance was better than theoretical advantages, and went with the lighter configuration.
The V10 uses an 83mm bb shell, so make sure you buy a crankset/bb that is compatible. Proper chainline is 56-57.5mm. If you buy 83mm compatible Raceface or Saint cranks, you already have the correct chainline/ bb length spec. If using Truvativ Howitzer system cranks, you must use an 83mm bb with a 56mm chainline. They don't sell their bb by spindle length, but by chainline. If you are going to use ISIS cranks, use an 83/128mm.
The V10 has a pretty low bb, which gives it great cornering and handling qualities. Because of this and the amount of travel it has, we recommend 165mm or 170mm cranks.
Tires seem to vary so widely these days that we hate to give concrete numbers. 95% of 2.7" tires will fit in there, and definitely any 2.5" tires.

The V10 has a big, thick, durable headtube, made for extreme use. We haven't seen any problems whatsoever with people damaging them. We recommend standard length headsets. As long as your headset is pressed in properly, and you keep it adjusted, you will be just fine.
Also, our head tube is internally and externally butted, allowing for really thick walls where needed (at the ends), and a little bit of weight shaving elsewhere. This butting makes it really difficult to remove the deep press headsets because the tool ends up hitting the butt shoulder, and not the headset. Do what you wish, just be prepared with a lot of beer, pizza, money, and time when you ask the shop rats to yank your deep insert headset out 2 years down the road.
The V10 uses the ISCG05 interface, so most guides that are sold with these mounts should fit.
Our favorites here are the E-thirteen SRS and LG1, which will bolt on with minimal hassle. We have also tried a Gamut ISCG05 and the MRP G2 with good performance on both. Many bottom bracket mount guides should work as well, but we haven't personally tried any of them but the Gamut (which works well).
The V10 requires a 150/12mm through axle rear hub, which is available from many manufacturers. Our favorites are DT Swiss, Chris King, and Hadley. The frame is supplied with an axle.
30.9mm. Make sure you always have a minimum of 4"(100mm) of post inserted into the seat tube at all times. Any less insertion and you can break off the top part of the seat tube, which is not covered under warranty. If your seat is too low, the tire can rub on it when the suspension bottoms out, so we recommend you remove the spring from your shock and fully compress it before cutting your seatpost. If you feel the seat is still too high when you have raised it enough to clear the tire, try a low profile seat like the WTB Silverado or Devo.
You can use anything you want, with 203mm being the maximum.
34.9mm (supplied with frame)
The hub will work, but the rear derailleur is not compatible with our dropout.
