Lightweight Ventoux / Gipfelsturm 240 Carbon Fiber Tubular Wheelset
The wheels on my new Trek Madone 6.9 SSL (Feb 2011) will be replaced by Lightweight Ventoux 240 carbon fiber wheels with Veloflex Record (front) and Veloflex Sprinter (rear) tubular (sew up) tires. I'll trade in the stock wheels for credit, since I already have two sets of the ZIPP 303 carbon fiber tubular wheels (and one rear 404). The Lightweight Ventoux 240 wheelset are intended to be my climbing wheels.
Clincher wheelsets: a sudden blowout from the clinchers that 99% of riders use is not an option for me. I’ve had two blowouts from clincher rims, and it’s too painful— I have the scars to prove it. And a blowout could be deadly. Tubulars have proven their merit to me for 4 years running now.
Lightweight wheel names
As of 2012, Lightweight has renamed the product line:
Lightweight Standard = Lightweight Mielenstein Lightweight Obermayer = Lightweight Mielenstein Obermayer Lightweight Standard Clincher= Lightweight Mielenstein Clincher Lightweight Ventoux = Lightweight Gipfelsturm Lightweight VR8 = discontinued, see Lightweight Autobahn
Since the Mielenstein Obermayer is a VERY different wheel from the non-Obermayer Mielenstein, this is terribly confusing from a customer perspective. They are totally different in feel, even if the two share the same rim profile and otherwise look identical.
WITH TIRE AND SKEWERS and cassette
Front: 700g (Veloflex Record tire)
Rear: 1105g (Veloflex Sprinter tire + 11-28 DuraAce cassette)
= 1809g = 3.99 pounds.
Weight Load rating
Because the wheels are rated for total body weight + bike weight + “luggage” (clothes, water, excess winter belly fat, etc), I was right at the weight limit and opted for the slightly heavier and stronger Ventoux 240 model.
The Lightweight rear wheel with with cassette and mounted tire is much lighter than most wheels without a cassette. I’ve never felt such a light rear wheel before, and yet the wheels are impressively sturdy. The entire wheel, including spokes, hub and rim, is one single piece of carbon. Amazing.
Wheel magnets are built in to both front and rear wheels, actually part of the spoke, placed opposite the valve stem of course. Wheel magnets won’t work with every sensor, but they work fine with the front fork-mounted sensor I’m using.
For 10% more, Lightweight offers a 3 year replacement guarantee on the wheelset against just about anything, including running over them with your car by accident. So I think Lightweight believes their wheels will last.
