Hi,
I bought used a set of wheels and was thinking about making them lighter. I weigh 220 pds so keep this in mind. I am currently running 32 spoke Chris King hubs, 14/15 spokes, brass nibs, and Mavic CXP-33, Pedros rim tape.
Front is currently 786 grams
Rear is currently 967 grams
I want to lighten up the wheelset. I was thinking about maybe going with DT Revolution 14/17 spokes. And maybe going with alloy nipples.
Excelsports says DT Revolution 14/17 spokes set of 32 is 157grams vrs DT14/15 spokes 32 is 213grams and going to ally nipples would save another 10grams each. So I am guessing
maybe I could get the front to 740 grams rear to 900 grams?
Again, I weight 220pds. So is going to 14/17 spokes going to flex to much. I have never ridden them nor seen them. Or is there better/strong light weight spokes out there.
Or am I wasting my time. Yes I want to keep the Chris King hubs. I also thought about going to the IRD CAdence rims, 400 grams vrs 470grams for the Mavic CXP-33s.
Any suggestions......

You can get away with the 14/17s on the front and rear non-drive, but you'd better stick with the 14/15s on the rear drive side for someone of your size. Alloy nipples will also be o.k. providing you build them with lots of lube and keep them from corroding. I've had great luck with Sapim locking Polyax nipples.
As for the rims, CXP-33s are very resilient, have great eyelets and are pretty dent resistant as compared to lower weight/profile rims. It's a trade-off that you must "weigh". I don't have personal experience with the IRDs, but if you do want to go lighter, I won't hesitate to recommend Velocity Aeroheads with the assymetrical model in the rear to reduce dish and increase wheel strength/stiffness. That would be a nice way to recover some of the stiffness you're going to give up with 14/17s on the non-drive.
Last, but not least, if I were building them I might even go twisty for even a little more rigidity.
Good luck!

As Twisty said I would not suggest revo's in the rear. If you really need to have light weight spokes in the rear use cx ray's or DT aerolites. They weigh the same as revo's but are much stronger.
Hey Twisty, I found a new spoke at Interbike. Bladed Ti and the dimensions are 2.3 at the bend, 2.0 after, 0.9 by 2.1 blade and 2.0 end and a 260mm weighs 3 grams. They also had some double butted ti spokes and the ti alloy they use is some high strength unweldable ti made by Reynolds. Sounds like spokes are a perfect application for it.

@ Bikemesenger:
Was it Reynolds making the spokes or just supplying the ti? How $$, availability, colors? Any claims as far as stretch resistance in the db version? At 2.3mm at the elbow, do you think they'll be too tight in some hubs? Thanks. You've made Interbike from home much more bearable for us all.

correct me if I'm wrong, but the CXP33s don't have eyelets, like the Velocity Aeroheads. anyway, I believe the IRD rims may not be best for someone of the original poster's size because they're pretty light... lemondpoprad, give Mike Garcia at odds and endos an email, he builds with the IRDs. actually, it's usually best to contact him by phone, but you will end up talking for an hour, he knows his bike parts very well. actually, I would call him and ask him to build the wheels for you. I'm nowhere near as heavy as you are, but if I were, I'd probably get deep section rims, like velocity fusions or mike's niobium rims. of course, if you ride light, you can get away with lighter wheels.

@ weiwentg:
CXP-33s do have eyelets, just not the typical "grommet" style of most eyeleted rims. CXP-30s and 33s have eyelets that do not go outside of the rim, but instead are internal and spread the pulling force of the nipple laterally against the semi-vertical walls of the aero-profiled rims rather than vertically in line with the spoke as in a traditional box section rim with a regular eyelet. Imo the design of the 30/33 eyelet is superior and I've never seen one pull through like normal eyelets can. You were half right though, Aeroheads don't have eyelets, just a little thicker rim wall where the holes are drilled for the nipple seats.

Reynolds makes the ti and a Tiawan company makes the spokes. All of the stiffness and elongation numbers were about the same as a cx-ray. I have some samples and have tried them in White Industries and Tune hubs and they fit in both of them. They are available in green, blue, magenta and ti dyed.
