|Still looking for a strong and widish rim around 450g||Jan Gerrit Klok|

I'm still in search of a strong 700c rim to be used for 50+mm wide knobbies, the so-called 29" tires. I'll be running discs.
As good and reliable rims for 32h 26" (559mm) use can be as light as 400g, I'm sure it must be possible to make a simularly strong 36h 28" (622mm) rim that weighs in at around 440-450g. I want the rim to be at least 21-22mm wide, wider is better for optimal tire stability.
The thing is, I'm building up a Gary Fisher 29" hardtail, that I plan to be the fastest thing on earth, for my 6'4" ass that is. I aim for a weight of around 21lbs/9.5kg, and every gram to be saved on the outside of the wheels is mayor gain.
I have been tiped to get the Salsa Delgado Cross rims, so I bought those, in 36h. Very rough product, looks very cheap, spent a long time to get moving tiny little alu bits of it. Not too impressive. Even worse, they were 530g each, while claimed as 460g in some places. Sure they're strong, at such a weight. I should've gotten the 32h ones, 36h would be overkill with my riding style and 4 spokes is over 20g per wheel. I get the rims from the USA to holland, not a very easy undertaking.
Then I've heard some vague things about WTB Speedmasters. Does anyone have an ACTUAL weight on those? And are they decent in strength or really noodly?
I already have a wheel with an Alex TD17 disc-only rim, looks cool and weighs 550g, but is pretty cheap. seems to hold up great as a front wheel in a semi-converted hardtail (see pic). Not a rim for my lightweight 29" bike though.
Velocity Dyad, any experiences or actual weights on that one? It's claimed at 480g, and advised for tandem use, which make me trust it quite a bit in terms of strength. If it's 560g however, it's not for me, I definately want to stay well below 500g and preferably over 21mm.
I could just use 36hMavic Open Pro rims, as my 32h front holds up great, but the tire stability would not be very good, as the rim is only 20mm wide for 50+mm tires. Weight will be around 430g, but I think I can do better than that.
ANY help would be greatly appreciated, my time is running out to build the wheels, I intend to race the bike in the beginning of August.
Oh, I'll be using Sapim CX-Ray spokes, alu nipples and American Classic disc hubs. That is, if no-one can give me any better idea's.
Thanks in advance!

Have you looked into Bontrager (Clyde) should be around what your looking for esp. since your building a Fisher (Owned by the same company).

|Thanks for the tip, but that one is claimed at 560g, in that range there is almost an unlimited choice from different brands.|

|I haven't used the Velocity Dyad, but I have built up three mountain wheelsets using the Velocity Aeroheat AT rims, which use the same rim extrusion.
They have held up very well. Haven't had any problems, and I weigh in at around 210 lbs, ride very aggressively, and punish the crap out of my wheels. Haven't ever taken a spoke wrench to any of them.
I would expect the same durability in for the Dyad. Can't comment on whether or not claimed weights are accurate.
A word of caution though, the Dyads don't use eyelets. I've heard that you should never use rims without eyelets for disc wheels. That said, I'm running the Aeroheats on my disc wheelset without problems, and have a friend running Velocity Deep Vs (without eyelets) on his mountain tandem without problem there either.
Hope this helps,
