Let's say I'm a really fast racer (Total Poser) and I'm finding my self in the need of some nice brightly colored rims to make my bike go faster...

Would it be possible, if I talked my friend-mavic-importer, to order some DeeMax ultimate rims only? Maybe perhaps ask the guy to send in a request since two guys here just happened to bust their rear rims. In theory this could give me the option to buy a lighter, cooler set of 819 (AFAIK they're milled 819's) 32h rims.

Only problem I see would maybe be the spoke interface at the rim? I've never taken a good look at DeeMax ulitmates.

Any paint-savy people know what color of yellow they are?


And how many seconds would this shave off my time at the world champs this season?

I thought that the DeeMax (not ultimates) were 823's. The ulitmates seemed to have smaller rims (width). They were lighter too so I kind of just assumed they were smaller. Next one down their normal line were the 819's so...
Can anyone confirm?


That's my beef with the DeeMax's. They look great and they're the lightest out there which is great paired with UST but there are just so many better hubs.

I last year I had my wheelset built from 729's laced I9's (I'm no hipster just got a good deal!). I cracked one of the rims due to a bad wheel build and replaced it with an Syncros DS28 and the change in weight was very relevant and noticeable. Made a big difference. And I don't know if I just got a DS28 made out of unobtanium by chance but it's holding up much better compared to my 729. The 729 is on the back though. 729 has tons of dents and likes to pinch flat a lot. But I'm a pretty heavy front tire rider and I probably hear the front rim give off that nasty ringing sound more than the rear. Yet for some reason it never pinch flats and it never dents and after a year of riding it is still true.

Very interested in the 823 like rims since they look a bit like DS28's in construction but bigger. They're just quite heavy.

I really want to give UST a shot too since I run higher than normal pressures in my tires as well. AFAIK, most UST problems come from having the tire at low ish pressures. If I run them high (30-35psi) by preference then I don't see the downside.

Thoughts?

Thanks guys...

I've got a couple sets of 823s and love them. I've stayed away from the DeeMax because of the Mavic hubs, never heard anything but bad about their hubs.

I am pretty sure that you're all sorta wrong, but I could be incorrect. ;) The Deemax rim IS a milled 823 but the Ultimate rim is not an 823 or an 819. Mavic has a history of doing this, the Crossmax SX uses a custom rim too. Too bad, a lot of guys including me would be all over the SX rim for AM wheel builds. 823 rims are pretty much nuke proof for me, I bet I could run Ultimate rims and get good durability with less weight.

EDIT: This got me to thinking (uh oh!) so I just checked the Mavic site. It looks to me like the Crossmax SX and Deemax Ultimate use the same 21mm ID rim. So there you go.

In the past you could buy all the wheelset rims separately for a huge price.

Not sure about what the rim actually is on the D-Ultimates, but check out this thread. A buddy on the team did Hope hubs and 823s. And yes, you can order just the hoops from Mavic factory wheelsets. I have an extra rear hoop for my DeeMax....just in case.

As for the mavic hubs. They have quick engagement and have worked great, but they do require more maintenance than traditional hubs IMO. They just need a quick clean and relube on the rear freehub or your freewheel will start dragging a bit. Front seems bombproof.
