i blasted my rear Sun MTX 36h this weekend and was looking for another option thats a bit lighter.
im a bigger rider(225lbs) who's hard on rims so thats why I originally went with the MTX's.
im not up to date with Mavic's newer rims, but the EX729 is looking like a nice bet as well as Sun's MTX 31 or 33 rim.

what else is a good option?



on another note, i have a Mavic 823(..might be a 819) where i reamed out the vavle stem hole a bit to use a tube in it and was curious if i could still use it for a tubeless setup.




thanks!

You can't use the 823 as tubless now as the valve is presta & is sealed with an O-ring.

729's look like a safe bet.

 

[.:Jeenyus:.]

729's are exactly what you are looking for.

i kinda figured it would use a o-ring and id be SOL.

come to think of it now, its probably a X819, but that should still be the same problem.
would this maybe work:

that will probably just pull through the hole.

I think about the only thing you can do to use that rim tubeless at this point is putting a tubeless rim string in it. Kinda defeats the purpose of buying a UST rim, but then again so did drilling it out.

go old school....MODO!!! that 'oughta handle your girth!

I am about 225-230 and the best set of rims I have had were 729s laced up to Hadley hubs. I think I went through half a dozen single tracks before I decided to drop cash on a set of rims that wouldn't taco when I looked at them wrong.

yeah when i built the rim, it was the only thing my buddys shop had in stock. i had no desire (and still dont) to run tubeless. i just thought i might be able to

ill be building them on my Hadley thats been killer as always.

i think ill go with the 729.
thanks all

729's on Hadleys were the most bombproof combo I've ever run.

Just in case you change your mind about tubeless, with Stans strips the 729's work perfect.

That sure wil pull through, although if you were to use it along with the stans yellow tape, you would probably be ok, seeing thats what it was designed to be used with.

For the OP, for suture reference, if you have a UST wheel, and want to run a tube, just run a presta tube instead of making the hole bigger. Keep it usable as a UST setup. When I was running tubeless, I always kept a tube, a rag, and a Co2 in my pack for the incase of flat, I would wipe the sealant out of the tire, take the valve out, and stuff my tube in till I could get somewhere to fix it properly. Only time I ever had presta tubes for the big bike.

You know they make presta tubes in a 26"

 

[IH8Rice]

yeah i know i should have used a presta tube, but i had just ordered a dozen presta DH tubes that i didnt want to waste. i had no intention in using a UST setup until i got an extra 2 from wheels that i use with tubes....so i basically have 4 DH front wheels, all with tubes

I had bad luck with 729's I completely destoyed three of them two summers ago before I gave up on them and went to a WTB laserdisc freeride rim and it has been great I even cased a road gap last summer and it was fine.

 

[TheTruth]

I ride 721's and they flat spot like mothers. I would have to agree that the 729 is weight weenie approved and strong.

Probably a bad build or three. My WTB rim had many dents after one year, and my 729 has exactly zero after two years.

 

[toodles]

Give the Alex Supra D rims a go. They're bloody strong, a good weight and have impressed me since I switched to them from Mavic rims.

 

[DownhillR3]

I've been on 729's for two seasons now. haven't really had a problem with them minus the normal loose spokes. I'm 145lbs. with gear & this season i'm noticing the blue 729's on new Shimano Saint hubs are getting out of wack easier. Or maybe it's just my riding style.

All in all, I think you'll be happy with the 729's.

Yep. Lighter than 729's and at least as strong.

You can buy a solid metal schreader valve at NAPA for a couple $$$. Comes with a gasket and everything. Works great.

I have had great results with WTB rims. Quality has gone down a bit over the last couple years but still good bang for the buck over mavic.

hmm ill have to give that a look. id just need the rim strip right?

most likely not because there are no spoke holes on the outside of the rim. You might need something to seal it up tighter if you don't use UST tires, though.

 

[SuspectDevice]

Just call Notubes and ask for Mike B, or find him here on RM. They will make up a schrader valvestem that is appropriately sealed to keep everything Kosher on your mavic rim...

I found WTBs cheap, light and strong, but they have (had?) the shallowest rim center I've ever used (except for Singetracks), so mounting a tire was always a bitch, and running tubeless was impossible.

cool, thanks buddy

the 823 i have is ridiculous to mount a tire onto because of how shallow it is.

I'm running the Laserdisc DH and FR on my race bike and the trails on my 6" bike. All 3 wheelsets are ghetto tubeless. I've been using the DH rims for close to 10 years without any issues.
The quality concerns I speak of pertain to the use of single wall eyelets vs the double walled ones used in the past. When compared to a 729, they are still lighter and last just as long.

sooo why couldnt you use 1 of the 12 presta tubes that you ordered?

2nd in DS. crashed in practice run before DH race run. drove home to jersey to get 4 stitches and some lady digging chunks of platty mud outa my arm.
yum

 

[yuroshek]

thats because you said "aight 1 more practice run" right?
