Why the 19mm internal rim width?

I'd consider the HED Jet 4+. Those with some 25mm GP5000s will be amazing for long days in the saddle.


Also, for breaking in the wet consider Kool Stop Salmon pads. They instantly make the 8000 brakes outperform DuraAce.

Your needs put you in a very niche market especially the need to go 19+mm internal on 38mm depth allow rim. The issue of tire clearance and rim width is also a bit complex here because it depends on what is limiting the clearance. If the problem is causes by tire width, rather than tire height, you may be better off going for a narrower rim paired with the 28mm tire.

I have had good luck with DT Swiss rims and the the RR 511 kinda fits your needs. If you had them built with something like DT Swiss 350 hubs you would get a really solid wheel set for a reasonable price. They are a bit narrow though and if your budget stretches to the $1k+ range the other wheels you list may be better.

I used the 19 because thats what the AC are and I know they will fit in the frame with 25 mm tires. Not sure if can go any wider. The pinch point on the frame is behind the bb side clearance. I also thought that narrower rim with wider tire wasn't good.
I'd like a 38 but have seen some in only 32 or so. Given my weight don't want a much taller due to wind.

Also wondering about the FLO 45 Carbon Clincher a little more rim but has both carbon & al braking surface.

Thanks for this thread. Much needed.
