The reactivity of the wheel-set on climbs is unbeatable. The overall weight of the two wheels is only 1518 grams which make them easy to climb with.
Very smooth and good price with Biketiresdirect.com
Old and retired, but still like to ride as fast as I can. Was once a Cat3 racer, I am comparing these wheels to old
ROLF Vector Pros and new Rolf Prima Echelons. Both Rolf wheels ride and corner well and spin up quickly, but the racing zeros are in a league a head of the the other wheels. They are really strong wheels also as I found out when I cut a corner to tight and hit a huge pot hole and was surprised that I did not break the wheel or get a pinch flat. I do not do lots of climbing but what I do has been somewhat easier as the wheels seem to spin so easy. I got these on sale and at the sale price I think they are a great value. I am sure there maybe better wheels out there, but if you you do not want to spend 2000.00 plus on a set of wheels that will make you faster try these, I think you might like them I know I do.
Light wheels make a big difference when climbing and these are some of the lightest. But what about your reward for all that climbing? The high speed descent... These wheels are stable and quiet at high speed and they have a huge braking surface. I have used these wheels for RAMROD, High Pass Challenge, Copper Triangle, Triple Bypass and several trips up to Timberline Lodge (your basic epic mountain rides) and these wheels quickly transfer power on the way up and on the way down. And when I have hit the inevitable mountain road pot holes, these wheels remain true. In fact I've gotten several years of use on these wheels without ever having them trued. Great wheels.
