I have a new Arenberg coming and it has Mavic SUP rims. I can not find them on the Mavic site. Anyone know anything about them? How do they compare to other more common wheels out there now? Looking for comfort & durability. I don't race at all, just long rides and looking to do centuries.

SUP applies to current mavic rims.Means after forming the rim is welded at the joint rather than pinned.

It's just a guess, but they're probably Open Pros (an excellent choice, IMO). Check the rims here. Mavic rims can be purchased with assorted features, such as CD, UB, and SUP.

What I said was not a guess.It came dirtctly from a description of rims at excel.Open Pros and cxp33s have it on the rim in small letters.Older reflex rims have it on them on BIG letters So one could read it as Mavic SUP just as he said.

Directly from Mavic
SUP
Concept :
After bending, the rim joint is arc welded.
The welded seam is then milled by digitally controlled machines.
Benefits :
- On a SUP rim, the resistance of the joint can increase to 90 %. On ordinary sleeve-joint rims, resistance at the joint is
40 % to 60 % lower than on the rest of the rim
- No visible joints that could cause shuddering during braking.
- The "monobloc" geometry makes wheel building and balancing easie.

Not just "current" rims but older rims as well. Such as the venerable 217 SUP and the 117 SUP and the 117 SUP CD all of which are many years old.

Huffman, I guess we still never answered your questions. Congrats on the new bike and welcome to Bikeforums.

Mavic makes a good quality rim. Comfort will depend on the model. The aero profile rims (cxp22s & cxp33s) will have a harsher ride. In terms of durability, you're in good shape, no matter what model. If the wheelbuilder has done a good job, you may need to get the wheel re-trued after a month or so, and then, barring wrecks or serious potholes, won't need to worry about it until your annual tune-up. Enjoy!

We'll look for you at the Blood, Sweat, and Gears and the Bridge to Bridge!

No, but what I said was, and referred him to a page with rim profiles so he could make a determination. I assumed he was trying to figure out the model... but was looking at the features. Knowing the rim is a Mavic SUP is analogous to knowing a vehicle is Ford w/in-dash CD, but not knowing whether it a Focus or an Expedition... true?

The question was answered to the extent it could be given the information.It's a Mavic rim with a welded joint. That's all one do without a model.The model may have been indicated by a decal that came off. That happens.The mavic page only shows current models.It does not even show the not too old clincher Reflex Sup that I have. I also have a current Mavic catalogue that is no help either given the suplied information.Maybe he will have a much better cllue when he gets the bike and has more info to work with.

Thanks for the feedback. Sorry it took so long to get back but here's the scoop. Mavic Open Pro, SUP, 32 spoke, Wheelsmith built with Wheelsmith spokes, Ultrega hubs. Not stylish but look to be a good utility wheel set. Again, not racing just riding and looking to do some centuries. Would swapping them out for a low spoke more aero wheel set (something like Shimano R540) help or hurt the ride quality?

Good info. I've just ordered new wheels for my tourer. Hope hubs, mavic T520 SUP's, stainless DT spokes

The hubs make the cost quite a bit expensive but hey, they'll last.

Good wheels.The R540 look cool,nothing else.Save your money.
