Wheelcovers can be made to various depths and dishes to accommodate shallow rims up to 100mm deep rims. We’ve carried out extensive wind tunnel testing, with our latest test runs happening on January 31st 2023. This was with independent engineers at Silverstone Sports Engineering Hub. Performance estimates are based on a number of assumptions. Individual results may vary. Key assumptions are:- Keep Your Bike in Riding Shape: Best Bike Tool Kits ● Best Repair Stands ● Best Bike Pumps The Best Bike CoversIn time-trial and triathlon racing, many people equip their bikes with an EZDisc or a full rear disc wheel. These wheels stop the air from getting caught in the rear wheel, keeping the drag as low as possible. On windy days, an EZDisc will create a sail effect, pushing the rider along even faster. Bike covers protect bikes from the elements when being stored in areas such as a shed or sheltered, but open canopy area. They are also extremely useful for transport and can protect the bike from damage and protect other items from oil or mud transfer. If you’re moving home or taking your bike abroad, you may want to invest in one of our bicycle covers to help keep it safe. Waterproof Bike Covers

Wheelcovers are available in Classic, Lightweight, Premium and now new Ultra lay-up. The Lightweight and Premium both offer around a 10% weight saving over the Classic, while the Premium also features a distinctive 'spread-tow' chequerboard carbon finish. The Ultra also has the chequerboard finish but boasts a further 10% weight saving over the Lightweight as well as exclusive Gold or Silver graphics. An Ultra wheelcover for a deep-rim wheel can now add less than 200g to the wheel weight.There’s nothing worse than rainwater drumming down on your precious bike and causing it to rust and corrode. Keeping your bike stored safely indoors may not always be an option and sheds and canopies are rarely watertight, so investing in one of our high-quality bicycle covers helps to ensure your bike is protected against the worst. In-Transit Bicycle Covers A flat disc is generally found in wind-tunnel tests to be worth a saving of about 30-40 seconds over a 25-mile time-trial compared with a standard road wheel. A lenticular disc or a set of wheel-covers can improve a further 5-10 seconds on that, possibly more in a stronger crosswind.

You will go faster using an EZ Disc regardless of speed as long as you cycle over 25kph. If you take longer to cycle a distance an EZ Disc will save more time then someone doing it faster.Every competitor must ensure that their machine is so constructed, equipped and maintained as to be capable of being ridden on the road safely at all times and in all conditions. The riding position shall be set so that the competitor has good forward vision when in a competitive position. In particular but without prejudice to the general principles of this regulation: Simply put a pencil line around the disc on the wheel and overlap your rim tape (electrical tape) on this line.
