Any aluminum rim with modern profile (e.g. wide), that is below 440 grams is not something I'd consider. Hopefully, sidewalls are not as thin as Pacenti SL23.


No other rim has the ISM that allow more material next to the spoke hole. Pacenti has no eyelets then the stress repartition is not as good. So basically there is nothing similar to the Pacenti case... The difference between two levels of engineering.

got my first boxes of open Pro's. weight 425g for a few rims I weighed. internal width is 18.6mm for the rim I checked.
ERD 593mm. Depth at the spoke holes is 25.2mm and if you think about the archetype which has the same depth and ERD, the nipple bed there is 4mm thick so i doubt the new open pro will crack.

Here we go then finally got my wheels for my retro rebuild that I'm doing. The Mavic's came out at just the right time as for a steel bike that's approaching 30 years old it demanded Mavics and I was thrilled they released these new rims. I've had them mated up with Campagnolo Record hubs. And yes they're polished rather than black! The anodising has been removed and polished up with shield logos applied which was essential for the chrome plated 3/4 stays. I have some silver alloy Neutron quick releases to complete the job. So they're 32 hole built with CX-Ray silver spokes. The weights also include rim tapes though I'm not planning to run tubeless on these. So a front of 719g and rear of 838g gives a pair of 1557g including rim tapes which I think is pretty decent.

Sodium hydroxide will remove the black anodising then just elbow grease to polish it up. Obviously the whole hub needs to be stripped apart first.

I tried that on a black stem once and it did naff all. I eventually got all the black off with sand paper but the surface was rough and I could not be bothered polishing. /maybe soaking in a bucket of NaOH is better. cant leave a bucket of that around with a 5 year old in the house.

Thank you for the comments. It's going to be a mixed bag of components some dating back to the age of the original steel frame ie delta brakes, aero seat pin etc but then paired with modern 11 speed kit which is the last athena silver 11 speed I could find, along with those wheels that had to be polished silver hubs. I'll do a thread on it at some point in the next month or so once I'm done 8)

Anyone know more about when the Exalith version is due to be released? Also wondering about availability of the disc rims without brake track, lots of stores have added them to their websites but none seems to have stock at this time…

Exalith is likely to be end of the year or thereabouts.

So these are 19mm internal, 22.8 external. Anyone have thoughts on whether these would be a worthwhile upgrade over the Shamal C17 (which measures 17mm internal and 22.5 external) with 24/28 CX-Rays to Tune Mag/Mig hubs? These would come in a good 100-120g lighter (depending on real world rim weight), but at those internal/external measurements would there be a significant performance advantage?

A) Will they be as stiff?

B) I personally have found that 23mm Conti S2's interface very smoothly with the Shamal C17 rim. But 19mm / 22.8 seems to be a trickier combination... 25's would be required but appears as though they'll end up inflating far wider than the Open Pro rim (even at lower pressures) - will this compromise handling?
It's ALL about the bike.
