Mavic have a well deserved reputation in wheel building. The Aksium is their budget range, but perform well for their relatively low price of £130.
The rims are aluminium and spokes are steel.
There are 24 spokes on rear and 20 spokes on front.
Weight of Mavic Aksium
If your looking to save every possible gram then Mavic Aksium is not for you. (for example, the Mavic Kyrsium are nearly 500 grams lighter, but double the price.
MDT Disc wheel. Cost £500. Quite light. Good Value
Buying a disc wheel is one of the best ways to improve the aerodynamic performance of your time trial bike. They are expensive - you can easily pay £500. But, they do make a difference. Also, the faster you go, the more aerodynamic drag they save. Disc wheels work by smoothing the passage of side wind. Less wind turbulence means less drag and faster times.
A flat carbon disc wheel has an aero drag of 97grams. This compares to an aero drag of 154grams for a standard 18 spoke wheel (source: bsn)
The weight of a disc wheel is not as important as the aerodynamic aid. Even on the hilliest of time trial courses, you will go quicker on a solid disc wheel. Chris Boardman used a disc wheel for winning the national hill climb championship. I don’t advise this, but aerodynamics are much more important than weight. Also if you are going to be doing a lot of hilly time trials, look to buy a light weight carbon disc - some of them are surprisingly light.
