Rappstar, you are now saying 3 statements MAY be incorrect - however the tone of your original post was clear, direct and "competitor bashing". It isn't just what you say it's how you say it.
You then mention individual variances/tolerances in measurements - well that may explain the HED not fitting frames/measurements with Zipp's calipers too.
I certainly appreciate your input, expecially when someone has a question relating to something you've used. I just didn't really think it was appropriate the way you handled your first post.
As for blaming frame makers, wheel makers etc we don't need that (not specifically directing this at you Rappstar). It's just the case that as both frame makers and wheel makes try and fill the same gaps there will be times when things collide. The thing about Zipp wheels are there are a few options if you have that sort of frame that is tight fit - you can go with the 900 which is a flat disc and there other deep wheels appear to be a bit thinner then HEDs. Hed doesn't appear to have that option.
While I'm at it - if I have standard Alex rims (30mm deep) for training, and then a set of Jets or Stingers with the new C2 rims for racing, does that mean I will have to adjust my brakes (which don't have a quick release adjuster) every time I put my race wheels on? And what about Zipps wheels, is that a similar story, or am I right in assuming that Zipp wheels are still relatively narrow at the braking surface.
And get the 808 Firecrest carbon clinchers out soon Zippo - we want to check them out. :):)
Nope, reread what I wrote. I made three statements in my OP:
1) the wheel will not fit in SRAM calipers, older Shimano calipers, or other narrow calipers such as ZG calipers. This could be construed as being three separate statements, though, in which case I made six statements (or seven if you include "other narrow calipers" and ZG calipers separately)
2) the wheel was tested with a 21mm tire, which will void HEDs warranty, making the test results somewhat impractical since it's a big risk to run the setup as it was tested, by HED's own admission.
3) The wheel will not fit in Specialized frames or other narrow-stayed bikes.
Of those statements, #2 is undeniably true.
#3 is slightly debatable in that Vince has said it will fit *if you get it built on special narrow flange hub.* The measurements that Zipp took of the wheel indicate that this is not the case, and that even with a narrow flange hub, their measurements of the rim (what they measured was given by me above) indicate that it still won't fit. HED does not publish the dimensions of their rim, and Vince has not made them available here. But at the very least, you need to have it built on a special hub, something which is mentioned nowhere on HED's own website. And worse case scenario is that based off caliper measurements of the rim, it won't fit regardless of what hub is used.
The statement(s) which seems to be the most debatable is whether or not the wheels fit SRAM calipers. Another poster has confirmed that they do not fit on ZG, so that's clear. Someone posted that they do fit TRP, but then someone else said no, so at the very least, it seems like it's a very tight fit, and may be related to whether or not the pads used were new. The "clarification" (not backtracking, IMO) that I wanted was regarding pads -the folks at Zipp said they were only referring to the wheel not fitting with new, stock pads, not shaved pads or some potential brand that makes narrower than normal pads or some other potential interaction with the brake as a unit.
On to your next question... Given what you've said about your training/racing wheels, yes you will have to adjust your calipers. As for Zipp, it would depend on what wheels you used. If you were using any of the current generation of clinchers, you likely would not have to adjust your calipers (I say likely because there is occassionally some variance with the *height* and vertical placement of brake tracks on certain hoops). But if you were going from Alex-->Zipp tubular rims (or 404 carbon clinchers), then you would need to make changes.
