I'm in the market for a new climbing wheelset, either a factory set or getting a pair built. If I'm going to spend some money I want something that is going to be light! 1000g +/- or under...
Suggestions would be most welcome! (I'm 75kg by the way).
A few of us are going to build these up for Everest Challenge:------------
We should have rim and wheel pricing this week on the new Stan's 340 rim from Alex!!!

Here is a summary of key features for a steep climber and very fast descending wheelset.
After speaking with many people, my take is that using brakes on Everest doesn't occur too often but speeds will be in excess of 50 mph so heat will build up quick when you do!
Lighter Set (goes up hill faster and with less effort)
Sapim CX-Ray Spokes (Aero, light, stiff, and excellent yield strength)
Alloy Rim (less chance of overheating and rim compromise)
Lighter Tires and Tubes
Cork Pads (use for carbon rims)
20/28 or 24/28 (if 180lbs or more seems safest)
20/24 (excellent if under 160lbs, and should be fine up to 180lbs)
Stan's ZTR Alpha 340 Rim (lightest alloy rim (350g) and excellent in 18/24 for up to 180lbs)
C-4 B-18 Rim (excellent in 20/24 or 20/28 configuration)
Carbon (it is always cool to look at and admire)
Lighter Hubs (least effect on a spinning wheel)
Less Spokes (if less than 170lbs, 20/24 will be fine)
Carbon Tubular (may get hot and glue may get soft with heavy braking)
Kinlin Rims (excellent in 24/28 spoke configuration, +/- in 20/24 for keeping true)
Sapim Laser Spokes (may not be as strong and are less aero than CX-Rays but cost less)
Carbon Clincher (may get more fatigue from overheating and wheel compromise)
-this option would be my last choice. Also, alloy rims are about the same weight in a box rim.
Ti Spokes (flimsy, costly, lightest spoke, and not good recommendation from most builders)
A super light alloy clincher is the least costly and using the new Stan's 340 rim can get build weights in the mid 1100 gram range with CX-Ray spokes and light hubs. You wont have to worry about overheating, delamination, or using special brake pads. Alloy rims are cheap to replace and can be used as an every day wheel after the race.
Weight Weenies Galore:
Carbon box tubular rims, CX-Ray spokes, and light hubs can get builds under 1000 grams!
