My old D3.1 rim was 628g inc the inserts. They then changed the name to EX823, but the rim was identical. 2006 they bought out a new EX823 with a different cross-section.

I assumed the weight was very similar, turns out it's a massive increase to 716g!

Still, I've had mine for over a year and they're still running straight with no significant dings or flat spots, so I guess I shouldn't complain too much!

Ran that rim all last year and it was great. Performed better than the 729 rims I had run since 2001. Plus I could finally go tubeless the right way. A lighter version would be nice too especially for the front wheel.

I find that they are one of the only rims that I don't end up dinging the sidewall. Almost double the price of anything else up here, but they last all season if not longer.
 
I do a bit of internet searching for those lighter/older rims. When I started at my old shop, they had a bunch, so I picked them all up. The lighter ones have a indented bead run along the outside of the rim and they are about 100 grams lighter per rim. Same durability (for me) and less rotational weight.

Got a set for the new DH rig. Actually laced them up with DT Rev spokes, well see how it lasts.

I ran the 823 last year too, great strong rim.
There is a reason why it is 100g heavier than the old one, the old ones dented way too easily and a dented tubeless rim is worthless.

the ex823 uses a "special presta valve" right?


anyone of you have tried to used a schraeder valve? i mean a customized one to fit and seal the rim.

i have a "customized" one sitting right next to me, but it was used with ghetto tubeless, so i can't assure you that it would still work with UST.

Why would you want a schrader valve/drill your 823's? The rims come with a schrader adapter and any bike shop sells those adapters for < $1.

WOW, makes me love my Arrow FRX's even more at only 639g with no eyelets to rip out! I am a weight-weenie and didn't even know it! LOL

its good to hear all of this after building up one for myself and when i get the money another for the front.

I'm fine with a weight difference if the sidewalls are a little stronger, because that can definately be the make or brake of a UST rim. That and I have a tendency of denting a sidewall every now and then.
