I bought the EZ Disc Super Lite as I have a lovely DT Swiss wheel set and couldn’t afford to buy a disc wheel, and I’m so glad I made that choice. I used it for the first time at IM Wales - a hilly course - and it was fast, responsive and so much fun to ride. I didn’t feel extra weight on the climbs and it helped me move up from 70th out the water into the top 20 overall off the bike. For anyone in two minds, don’t hesitate, I can’t recommend it enough!
I was lucky enough to do some wind tunnel testing with the EZ Gains disc cover myself. With the disc cover added to my Reynolds AR80 DB, I made a gain of 9 watts at 40 kph! I was actually surprised how easy the disc is to install, take of and re-install for those weeks between racing. Can't recommend it enough!
Excellent product that works for great price
Fast international shipping, great price and looks great fit very well with the provided parts and instructions online.
Purchased the EZ disc cover before IM Florida and was blown away by how easy the installation was, and by how much of a difference the cover made on my bike split.
Huge PR and first time <5h on the IM bike leg, and it took even fewer watts than expected. This seems to be one of the best watt savings per dollar value on the market. Have told several friends to purchase this as well!
Packaged arrived quickly and the installation was simple and pretty fun. No complaints, I just wish I would have purchased sooner!
