Want to build some new wheels, looking for rim suggestions.

[CraigS]

I currently have Mavic 729's laced to Hadleys which are 4 years old. Still true and in good shape but I think its time to
update.
Will still use the Hadleys as they have been maintained and problem free.
The rims I'm considering are Mavic 823 and possibly Stans new Flow ex.
Looking to reduce some rotational weight but not give up durability. (I know, kind of an oxymoron)

My racing days are behind me, I guess I'm considered a weekend warrior now.
180lbs geared up and they will be mounted to a Demo8.

Suggestions?

i'm on the carbon rims from http://www.light-bicycle.com/
and they are great
strong
stiff
light
and hold on strong.

cant see myself going back to aluminium rims.....

What kind if pricing, couldn't find anything.
Carbon rims for DH kinda scares me, I'm not sponsored :-)

Pic's or it didn't happen


As for aluminum rims, I've always had good luck with Sun Ringle rims. They aren't too soft (DT swiss) so they don't dent too easily. And they aren't too hard (Mavic) so they don't pinch flat very often.

for a DH bike, 823s > Stan's anything.

The new WTB Frequency i23s are a decent rim. I built up a set for a friend and they're still straight as an arrow, he isn't the smoothest rider around either....

Im on 823s and Hadleys (problem-free, bomber, kinda heavy), I dont think you will save a lot of weight from 729s to 823s. Main thing is the hubs, Hadleys are heavy, vs. Hopes or DT's (at least 100g difference each end). If you wanna go with a lighter set and still be 'dh' worthy, My suggestion would be Hope or DT 240 hubs to 721 rims. Good luck.

Saruti, id like to hear more about your experiences with those rims

[saruti]

I ride them for several months now.
Here trails are littered with rocks. And these rims Excellent survive.
I ride with a rear wheel 35 PSI and 26 PSI front.
I did a run with the rear tire no air after I've got a hole in the tire from a sharp rock, and what happened to the rim is a small Dent in the fibers. fixed with some super glue.
The wheels are still straight
What's nice is that they give their rims warranty. And in the event of a problem or broken, they send you a free rim. And charge you only for shipping.

I've been using the Flow EX for a few months now on my 7" bike and it really does feel stiffer and wider than the Flow. I think it's a legit DH rim for any reasonably smooth rider. If you want a little more beef the Spank Subrosa has been problem free on my DH bike for 2 seasons. If you want the width of your current 729s but lighter the Spank Spike. Unfortunately there's no carbon rims in the width range of true DH rims. Hopefully Light-bikes will make one soon.

Which bike do you have these rims on, and where are you riding?

[saruti]

2 different bikes
a set on my MKII trail bike
and a set on my 2011 DHR . the set on the DH bike is stronger 420g per rim
the set on the AM bike is 380g per rim

Mavic 819. I ran this on the rear of my DHR all over British Columbia this past summer as part of a wheel I hastily built myself. ZTR Flow (non EX) on the front. Both worked excellent, and are super light as well.

I have no reservations about running 819 on any of my bikes. I've been running them without a problem for almost two years on my 7" bike as well. My 823s now just sit as backups.
