Over several years, bike wheels have been tested for aerodynamic performance. To date, this is the largest independent dataset available. Popular brands such as DT Swiss, SwissSide, Shimano, Mavic and Bontrager have all been tested. This dataset was originally derived from wind tunnel test data but has latterly moved over to Dinitriev number with a […]

The Winspace Hyper X 50mm are highly regarded, they have very good aerodynamic properties and are comfortably the fastest wheels you can buy in 50mm rim depth. The Winspace hubs use standard 6000 series bearings of common sizes. This video shows you how to remove the bearings and replace them if they are worn or […]
***Please note the graph and the data on this page will no longer be updated. The main issue being the control tyre is no longer manufactured by Continental. Additionally, test methods have moved on and Dnitriev number will be used as the basis for future testing*** Precursor – The critics and those with a vested […]
The aerodynamic performance of wheels often grabs the headlines and the marketing budget but the reality is the hubs and the bearings within them will have more of a performance differential for the average cyclist. As an example, the power differential between wheels of an equivalent depth at speeds of less than 35km/h will only […]
One of the most controversial topics in the cycling industry is with regards the topic of Ceramic bearings and whether they do or do not reduce friction dramatically in riding. This article will address some of the concerns and topics associated with this debate and quantify the numbers. Internal Bearing construction – Ceramic bearings are […]
