Me: 220lb clunker, like to rip fast/technical DH / singletrack. Speccing a bike for light freeride duty. Max air is 5 foot to tranny and nothing huge or super gnarly.

Was thinking of going with the 819's for strength and weight saving over the 823's. Bike needs to be able do some uphill (25% of riding) but be able to pay back with sweet solid DH. Trails here are hard packed, dry and rocky.

Will the 819's handle my style of ripping ?

At your weight and riding style the 823 is the better choice. You are likely to burp/roll tires on the narrower 819.

Look into Mavic 721s. You can convert it to tubeless if you need to. 823's are kind of heavy for light FR. You can also try out DT Swiss 5.1Ds.

No, they can not be converted to UST spec.

I remember converting it to tubeless with Stan's in one of my old bikes. I never said 721s were UST.

The only CORRECT way to do tubeless (that will stand up to pounding) is UST.

I'm going to agree that the safest way is UST. A burp or bead blow out at the wrong time is a problem as in the pic bellow I got from the norcal forum. Looks like bead blow off with a Stans cloud. The tire is totally off the rim in the 2nd pic. (thanks Tracy!! I hope you didnt DNF)

I ran 6.1's and they do DT (Dent Tremendously). :nono:

Running 729's right now and they're solid. Just wanted a clean UST setup light and strong.

Hmmmm ? 823's are like 20 gms less than my 729's ? Then there is the huge gain by not having toobs.

If you run UST tires, then you dont save a huge amount. Typically, UST tires are about 150 gr more than their tubed counterpart. Now, if you run tubeless ready tires like myself, then you save decent weight.

Love the look on his face

He is going over the bars into the rocks and he has a 'yahoo' look on his face. I love it. I run 819 rims with 2.3 Maxxis High Roller and have never rolled or burped my tires. You get into the 2.5 tires and it might be an issue. I have no clue why anyone would not run UST tires except lack of tire choice. You just throw them on, put some Stan's in, and forget about flats.

Mavic really needs to release an 821. But for now between the two I'd agree with shiggy that the 823 is the better choice.

I would ride 821s. Mavic? Are you listening?

To the OP, 823s. You'd break/ burp tires with 819s.

 

[Psycho Mike]

I'm a 235lb rider, but as I don't do DH stuff and stay low, I went to the 819's. For FR / DH, go with the 823's, Freeride.

 

[BillT]

Ditto on Mavic needing to make an 821 and ditto on the 6.1's DT'ing (denting tremendously)

 

[Whafe]

I would run the 823 rims, great rims, am on my 3rd set..... In defence of the 6.1's, this was more or less the first batch that had issues, know peeps having a good run with 6.1's....

 

[watermoccasin]

If you want to stick with Mavic, the 823s are the right call. I'm your size and used 823s as my trail rims a few years back, and run 729s on my DH bike (favorite rims of all time). I didn't like the narrow profile of the 823s, especially in hard cornering. If you're not running tubeless, the DT 5.1s are awesome rims for guys our size and the riding you described; I've been running them on my trail/FR bike for the last year and a half. Everybody I know who runs them loves them. They are stiff and wide and lightish and TOUGH (unlike the 6.1s which dent when you look at them crossways).
