Teardown: Campagnolo Ultra Torque Crankset Mechanics explained in Depth

Campagnolo cranksets have a reputation of being well engineered and robust but they are not without their problems and quirks. This post explains one of those in detail which surrounds the myths of the preload system, the “safety clip”, the system stiffness (or lack of it) and the involved nature of a bearing replacement. Campagnolo Ultra Torque is found on many of the upper range of Cranksets including the Super Record and Record.

Testing to Find the Fastest Bicycle Wheel Hubs

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…
