Road Bike Fitting
Road riders spend longer periods of time in one position in the saddle and so a professional fitting is vital to optimise both speed and comfort. Not only is the frame size important, proper adjustment of the handlebars and saddle are also crucial.Proper bicycle size and positioning prevent problems from arising and largely determine the cyclist’s comfort and performance level. We work with the computer-controlled bikefitting.com measuring systems to realise optimum bicycle adjustment and positioning.
Our bike fitting procedure involves an in-depth conversation about YOU and the style of riding you do. For example; the distances you ride, the kind of terrain you prefer and whether you compete or not. We take into consideration any previous injuries or problems that may affect the riding experience and specialise in providing a personal service to all or road bicycle customers, male and female, from the first time cyclist to the pro-level competition rider and from school age into the advanced years.
Cleat Shoe Adjustment
This service worth £10 normaly is FREE when you buy your shoes and pedals from us.
The contact points that a rider has with the bike (seat / steering wheel / pedals) are essential for optimal riding position. The Standard and Professional measurements includes the optimal adjustment of saddle, handlebars and pedals. The missing piece is the contact of the rider on the pedals, which intails establishing the optimum position for the cleats. For this we have the Shoe Cleat Adjuster (SCA) .
- Placement of the cleats so the ball of the foot lies exactly above the axis of the pedal to improve power transmission.
- Through the shoe cleats, the position of the foot on the pedal is adjusted in such a way that potential twisting of the lower leg is avoided..
- Because the ball of the foot lies exactly above the pedal, the pedal travel is optimized resulting in smoother pedaling.
- The positioning of the ball of the foot exactly in the middle of the pedal reduces the chance of getting a burning sensation in the feet.

The Professional Analysis is the most extensive service. It is specifically designed for athletes who strive for absolute optimization of physical performance or those with particular physical problems, especially related to hip, knee and ankle functions. Building on the results of a Standard Analysis, the skilled operator employs the Position Simulator to adjust for the cyclist's ideal saddle setback.
The Position Simulator has three functions:
- To determine the exact seat angle of the frame, which is a direct result of the ratio of upper and lower leg length. This also calculates the correct fore-and-aft adjustment of the saddle which assists optimal power transfer and a stable position on the saddle.
- To determine an asymmertic seat position to compensate, for example, for differences in leg length which often leads to pain in the lower back area.
- To simulate the position that the bikefitting.com computer program has calculated and to enable the client to immediately experience this improvement.
