The 25mm internal 32 external are to be used only with 28mm nominal tires, 25mm nah wouldn't try this shit

The 23mm internal 30 external are the widest rims I would use with 25mm nominal tires
Agreed. Just trying to figure out if I’m a 25 or 28 nominal type of guy.

Anyone have experience with the oynx hubs? Curious about those. I9 hubs have been great but seem to let too much road junk in the hubs.

I used 23 nominal on 23 inner width no problems. Can't see why wouldn't work. It would measure 29.5mm as new and stretch to about 30.5mm.

It would expose tires sides too much and be a pity to mount
I've tried on enve AR 4.5 tough with no so souples tires meuh
Besides they were designed for 28mm minimal

Where the 56mm are said to be optimized for 28mm but not adviced against with 25
I had luck with 25 mm pro one on the front rim

Damnit, the wait for wheels is killing me. Only been 2 weeks and the rims are still in sanding.
The sanding seems to take for forever. The first set of rims didn't pass QC, so I am looking at "sanding" again :(

So I finally received my wheelset. It took from March 29th until May 6th for them to arrive. (they were shipped on April 20th). So patience here seems to be a must!

What should expect the Bon Jon Pass by Compass to measure out to on the Falcon Pro’s with the 25mm internal width? They are listed as a 35mm tubeless compatible.

I have the Compass 28mms on my 21-28mm (front) and 23-30mm (rear) and they measure 27mm in the front and 29mm in the rear so they measure very, very close to spec unlike Continentals, so I would recommend buying the size closest to the external width (no need to size down).

Yeah, so how does this work on products that we've already paid for?

It's not possible to pay import tax when ordering, it's always paid after the item has entered the country before it's released to the customer. It has nothing to do with the company you ordered from as it's the US government that imposes and collects the tariff.
It was announced back in December last year that the 25% tariff would be delayed but would still come into place at some point in 2019 so that should be enough notice for most people.

Hello guys I see that the 105 rule and the big tire trend makes you like those always bigger rim however I have a soft spot for the 55m 25mm wide and I wonder if I'm wrong.
It is for tri/Aero purpose without sacrificing too much on climbing. I plan on using gp5000 TL. They appear to inflate a bit smaller than regular gp5k they mount at 25.3mm on my 17mm internal rim.
The 28mm rim is a V while the 25 is a bulging U so the widest point is really a 28. The 25 gpk might be a touch bigger than the brake track, about 1mm but smaller than the overall profile.
Your thoughts ?

I'm glad I got my wheelset before this went into affect.

If you want to ride gp5k 25mm tubeless and stay within 105% than the 56x30mm is the only way. I installed that tire on mine and at 90psi it went 28.6mm, and 28.4 60psi. It will stretch 1mm~.

So on the 46x28 rims they will match width after stretching, or even be a bit wider.

Unless you want to ride 23mm version with tubes, or you dont care about aero, which then means you dont need deep wheels to begin with.

There's not caring about aero, and not caring about optimum aero.
