Sorry I know nowt about "Open Pro" rims.
What are they

Brucey wrote:the evidence is that there is a small market for a hard-wearing rim brake rim for touring, if that rim is priced in the £60-£90 range. Rigida used to offer lightweight (training/racing) rims with their CSS treatment but they dropped them, presumably because sales were poor.
So I think that 170 euros is just too much.... I was hoping they would come in around £100 tops. You can buy four of the current model for the price of one exalith rim, or about nine inexpensive rims.....
cheers

That seems pricey for the Exalith treatment.
Unfortunately also confirms no 36 hole version, most of my hubs that need this rim are 36 hole. I am getting tired of wearing out Open Pro rims, my rear rim on my training bike is getting close to replacement at only 12 months old, kept very clean and not always used in poor weather. As Brucey states, the modern rims really are softer and wear more than they used to. So I would have been very interested in the Exalith version if in a 36 drilling. 36 hole rims seem to be getting much rarer across many manufacturers.
The MA40 was so much harder and took a lot of brake track wear. Still use a pair of Open 4CD rims too, these are on my racing bike when not using tubs, I suspect they have a lot of life left in them too. But the Open Pro is just plain soft.

I won't be buying, I'm vacuuming up more ceramic rims including from lesser known companies.
I managed to bag a mint open pro ceramic on dura ace 7700 front last year for £40 posted.
As for the width, I've run 32mm on an open4CD with a heavy load and never had issues.
