Bike Fit

Extended periods in the saddle mean the choice and fit of bike for The Fastest Cycle Across Europe must be correct. Cycling biomechanics expert, Andy Brooke, explains the importance of a professional bike fit and takes me through a standard procedure.

About one in 20 people who come to us are riding the wrong-sized bike

About one in 20 people who come to us are riding the wrong-sized bike, yet a well-fitting bicycle will help optimise your riding position and make cycling a more comfortable and efficient experience. A bike fit will also prevent injury by removing unnecessary strain on your knees, back and arms, reduce or eliminate aggravation of existing aches and injuries, and reduce rider fatigue by correcting your riding position.

The unique characteristics of each cyclist are taken into account for every fit. A pre-fit interview identifies rider experience, injury history and cycling goals for each client. This is followed by a physical assessment to identify range of motion, flexibility and core stability. These factors can influence how a cyclist will hold themselves on the bike and highlight any imbalances or asymmetry which could be improved.

Commencing the fit, the comfortable and efficient transfer of power from the body to the bike makes the shoe to pedal connection of utmost importance. Through a short exercise, any rotation in the ankle can be analysed and remedied, using insoles to add stability and alignment to the pedal stroke. With in-shoe settings configured, the position, rotation and float of the cleats are set to avoid instability and optimise the distribution of pressure over the foot.

With shoe to pedal connection established, the saddle and handlebar height and fore-aft position can be adjusted to best suit the form and requirements of the cyclist. Our 3D motion capture system measures cycling position to great accuracy, to determine the working angles of the body in motion. Interpreting this data, minute discrepancies can be addressed and positional adjustments can be made towards the perfect position.

Leigh is currently experiencing discomfort in the left proximal hamstring tendon. A more anteriorly rotated pelvic tilt will help to relieve pressure from the aggravated area and shift it forwards. Finding a saddle that best suits his body shape will also increase comfort by reducing localised pressure.

The data output from the bike fit specifies an individuals requirements, which can then be transferred on to particular manufacturers geometry specifications to confirm suitability and sizing. With the details Leigh has taken from today’s session, he will be able to assess the suitability of various bike designs, while maintaining a comfortable and efficient position.

Throughout the preparation and the attempt, I will be bringing you weekly behind the scenes videos and blogs, documenting what it takes to prepare for a world record.
