i also think that going just by the website that ada's are better and not just the weight, strength wise ceramic bearings etc. i know a guy that had lightweights and sold them as they flexed so much that they rubbed on his brake pads. i'd love to here from someone who's ridden them
That person can't have ridden the lightweights personally.
I own a set of lightweights, it is impossible to have them rub on the brakepads unless you forgot to close the skewer, or either the frame or the wheels have been badly damaged.
(BTW, They seem to be ok for Cipo and Ullrich, both not the lightest in the peloton.. On the other hand, you could see Jalabert climbing with his rear brake opened - he uses ADA.)
My personal experience is, that LWs are at least as stiff laterally as my '2000 "shamal"-style Ventos (at about 3/5 of the weight).
Independent Tests show the same:
German magazine "tour" had lightweights among many others in a big test in Issue 7/2002.
the ONLY wheels that were stiffer than the LWs was a wheelset approx. double the weight, built in traditional way with 32 2.0/1.8/2.0 spokes and brass nipples. (see Nr. (4) below)
All the other lighter wheels (Tune etc.) were WAY weaker.
some figures from the test:
(V=front, H=rear, N/mm = lateral stiffness in Newton per mm)
V: 71,4 N/mm (505g)
H: 58,1 N/mm (756g)
(Tune/Zipp 303, Bladed Spokes 2.0/1.0/2.2 v24 radial, h 28 2xcrossed)
V: 49,3 N/mm (491g)
H: 36,0 N/mm (604g)
(3) Tune/Mavic Open Pro/32 bladed Spokes 2.0/1.0/2.2 32 3x crossed)
V: 54,1 N/mm (676g)
H: 38,4 N/mm (781g)
(4) Ultegra/CXP33/32 round spokes 2.0/1.8 32 3xcrossed)
V: 84.3 N/mm (880g)
H: 59.4 N/mm (1090g)
The test of the ADAs mentioned above was also in "Tour" this year.
they were considerably WEAKER than the Lightweights (between 10 and 20 N/mm, if memory serves).
The wheels tested were Edward Zimmerman's personal set, who is a close friend of ADA's Cees Beers.
