​How Do I Place An Order?​

The CES Sport website is extremely easy to navigate, just select the wheelset you wish to purchase in the 'Shop' and select the colour scheme of your choice. Once you have done this, just follow the on screen instructions.

If you have any special requirements, either leave us a message at the checkout page, or alternatively get in touch via the 'Contact' page.

Why Carbon Rims?

Why are they so popular? Why does it seem like everyone wants a set?

Fundamentally, there are three basic factors people think about when they buy carbon wheels:

Reason 1: They're lighter than alloy rims

Reason 2: They offer improved aerodynamics

Reason 3: They make your bike look cool!!

What Rim Depth do I go for?

Mid section rims are anything up to 50mm in depth, and are very common on road racing machines as they are the best of both worlds. The increased rim depth has aero benefits but they aren't too deep and are still relatively easy to control and not too heavy. Best for racing on flat and lumpy courses.

Any rim more than 50mm is considered to be a deep section rim. Get these rims on the flat in a straight line and they will make you fly. The large rim depth cuts through the air with less wind resistance meaning you go faster for the same energy output. The increased profile does make them heavier and boy can they catch side winds. This make them difficult to handle. Best for flat time trials and races.

Occasional rider - A shallower rim will suit those starting out or the occasional rider as the rim is stronger, easier to control in windy conditions and descents

Regular rider - You will feel the benefit of a mid section aero rim as they get the aerodynamic properties with only a little weight penalty. A mid section rim is also easier to control as it will be used on lots of different types of terrain and weather conditions

Racers - Deep section rims should only be used for racing or time trialling as hey can be tricky to handle for even experienced riders in cross winds. The aerodynamic benefits on a flat course with no wind are impressive but to get the best out of them you have to really push them. They do roll nice in the right conditions though...

Clincher or Tubular Rims?

If you get a flat tyre with a clincher, you can change out the inner tube and continue riding fairly quickly. Tubular wheels are lighter, and sometimes cheaper, but you must use specific tubular tyres. These tyres combine the tyre and the inner tube into one piece, and must be glued onto the wheel.

When do I know when to replace my Carbon Rims?

Every time you apply the brakes, friction wears away the brake track and eventually the rim will need to be replaced. Wear the track too much and braking performance will be severely degraded, and the rims strength compromised.

When you can see wear on the rim track, its time to take your wheel to a dealer for further diagnosis and possibly retirement.

What is involved in the UCI testing procedure?

UCI approval required an impact test directly onto the rim. After the wheel is impacted, the run out values both radially and laterally, were tested to ensure there were no more than 1mm variance from the values before the tests were carried out.

Below is a video of our RC88 Elite wheel being tested.
