Gerard hinted that flat discs are the fastest on the p3 frame.

Is it the width of the disc that causes problems, or the flex? Would a zipp 1080 work on a P3?

he wasn't speaking to fitment issues, he was saying aerodynamically the flat discs are faster on that frame due to the close, extensive rear wheel coverage of the seat tube.

I believe the chain stay clearance issue is due to width though with bulgy discs

if you liked your zipp I would just trade it for a flat one!

I spoke with Zipp last fall when I was looking at a new rear wheel. The clearance issues come from the normal manufacturing variation of the chain stay width. That's why some people have fit issues and some don't have any problems. I would say since you own it, try it and see if it fits, and how much clearance you have on each side to make your decision

FWIW, I ride a 58cm P3 with a Zipp 900 Clincher disc with out any issues. I also tried a 1080 Clincher (which is narrower than the tubie version, but is still listed as a potential "fit problem wheel"), also without any fit issue.

I ride my '09 P3C with a Zipp 1080 (no PowerTap) and a Kinlin 30 (PowerTap)with disc cover. I am thinking about getting a Zipp 808 Firecrest with a PowerTap to use on both my '09 S3 and my P3 with a disc cover.

I have used both a Sub 9 and a Super 9 on my P3. They both fit fine although the Super 9 had a bit more clearance. I weigh 180.

I used a sub 9. Here is a photo and review of my bike with a photo of me on it climbing The Beast at St. Croix 70.3. No wheel rub:

That's good to know. I guess I'll give it a shot and see what happens. It's a great wheel, I just don't want to screw it (or my p3) up.

Hi all,

Could you give me some advice about disc/lenticular wheels for actual P3?

Which ones have you mounted?

Thank you in advance!

Out of interest what width of tyre did you have on the Super 9 ?

Do you have a classic P3 with the curved seat tube, or a new P3? This thread is from 2010, so it was for a classic P3.

I also have a super 9 and P3 without any issue. I always use 25mm Conti

Great. What size is the frame ? I am looking at a 2nd hand 48

51cm

I'd say definitely try it and see how much clearance you have. I use a Super 9 with 25mm GP 4000s and no issues. I did have to move the set screws back 1-2mm so that the tire didn't rub but once I did that I have no issues.
