Triathlon and Time Trial Bike Fitting
Please book using the calendar above. It shows live availability. For a detailed description of each level of service read more below.
Services on this page are applicable to any level rider using a Time Trial/Triathlon bike, or road bike converted for triathlon use with the addition of clip on aero bars. For road bikes, mountain bikes or hybrid bike fits, please see the dedicated Road/MTB booking page.
The booking calendars on this page show the most up to date availability and can be used to book a fitting appointment. There is a separate booking calendar for each level of service offered. Bookings can also be made by email or by telephone on 07917 938625. If you have questions that you would like to ask prior to booking, or would like to discuss a particular issue with the fitter before booking, then it is best to email info@bike-science.com with your name, contact number and any questions you may have.

Unless purchasing a new bike from us, then fitting takes place on the riders own existing bike. If you are at all unsure about what equipment to bring with you, contact us (there's a list on the FAQ page linked to above).
A fully adjustable fitting bike is available for "problem solving" issues (for instance experimentation with different length cranks.

Bike Sizing Consultation. 60mins
Remove the risk of buying a bike that doesn’t fit. A service for riders seeking advice as to what frame geometry will be appropriate for them. This service is for cyclists in the process of purchasing a new bike and should be carried out prior to making a purchase to ensure that the bike has a geometry that offers enough range of sensible adjustment to be able to achieve a successful bike fit once the new bike is built and ready for riding. If purchasing a bike from us, the fee for your pre-purchase sizing is deducted from the price of your purchase. If purchasing your bike from elsewhere, the fee for this session can be deducted from the price of any future bike fit with us on the new bike.
What’s included?
- Written recommendation of geometry requirements for any new bike purchased
- Stem length, crank length and handlebar recommendations
Technologies Used?
- Hand tool measurement with laser levels, digital spirit levels and goniometer
- Leomo Inertial Measurement System
- Fitting bike with adjustable frame geometry, stem length and angle, crank length and bar size

Level 1, TT/Tri Bike Fit. 1hr 30mins
Includes the positional setup of one bike. If you wish to bring more than one bike, please contact us by email in advance of booking.
The Level 1 bike fit option uses traditional static bike fit measurements. An excellent choice for new riders who need general guidance of a suitable set-up for their bike. For more experienced or higher mileage riders one of our higher level fits is recommended.
What's included?
- Assessment of rider position using traditional static measurements and Leomo Inertial Measurement System
- Adjustment of saddle height, tilt and fore/aft
- Handlebar positioning including stem length adjustment, bar rotation and length and position of tri bar extensions (new stems are available if required at an additional cost)
- Cleat positioning
- Detailed measurement report of final bike set up
Technologies Used?
- Hand tool measurement with laser levels, digital spirit levels and goniometer
- Leomo Inertial Measurement System (where applicable)
Level 2, TT/Tri Bike Fit. 3hrs
Includes the positional setup of one bike. If you wish to bring more than one bike, please contact us by email in advance of booking.
Recommend for the majority of riders who are looking to improve their race position for comfort and power output. This bike fit service looks at the every aspect of the triathlon or time trial riders anatomy, strength, flexibility and interaction with the bike. The process starts with a flexibility and lower limb anatomy assessment. The rider is then asked to ride in their current position and measurements taken from both sides to set a baseline and check for imbalances. Measurements are taken while riding at a constant power output to ensure consistency between measurement sets. All measurements taken can be viewed by both the rider and fitter during the fit process. Adjustments are then made based on judgements by the fitter and feedback from the rider followed by further measurements and adjustments as needed. Throughout the process the aim of each adjustment is explained.
What's included?
- Detailed pre-fit assessment of rider anatomy, flexibility and stability. Recommendation of post fit exercises for strength and flexibility improvement.
- Assessment of rider position and movement using Retül motion capture, Leomo Inertial Measurement System and gebioMized saddle pressure mapping
- Adjustment of saddle height, tilt and fore/aft. Alternative saddle models can be trialled during the fit, but if you are sure you need a different saddle, please contact us by email prior to booking as additional time can be added to your appointment to allow for saddle selection
- Handlebar positioning including stem length adjustment, bar rotation and position of grips (new stems are available if required at an additional cost)
- Detailed cleat positioning including in the shoe and external wedging and leg length correction if necessary.
- Half price cycle specific custom footbeds (although if you know you want footbeds, consider booking the Pro TT/Tri level fit or contact us in advance of your appointment to book some additional time)
- Detailed report included
Technologies Used?
- Hand tool measurement with laser levels, digital spirit levels and goniometer
- Retül 3D Motion Capture
- Leomo Inertial Measurement System
- gebioMized Dynamic Saddle Pressure Measurement System
Level 3, TT/Tri Bike Fit with CFD Aero Analysis. 5hrs

Includes the positional setup of one bike. If you wish to bring more than one bike, please contact us by email in advance of booking.
A high performance fit aimed at riders looking to get the best out of their race riding position. A detailed analysis of rider biomechanics and aerodynamics.
Recommend riders who are looking to optimise their race position for comfort, aerodynamics and power output.
This bike fit service looks at the every aspect of the triathlon or time trial riders anatomy, strength, flexibility and interaction with the bike. The process starts with a flexibility and lower limb anatomy assessment. The rider is then asked to ride in their current position and measurements taken using RETUL 3D Motion Capture from both sides to set a baseline and check for imbalances. Measurements are taken while riding at a constant power output to ensure consistency between measurement sets. All measurements taken can be viewed by both the rider and fitter during the fit process.
AiRO AI assisted Computational Fluid Dynamics software is used to give an accurate assessment of how bike adjustments and rider posture will alter aero performance. CFD offers near wind tunnel level of accuracy when it comes to determining which riding position will be most aerodynamically efficient without the huge costs associated with wind tunnel testing.
Adjustments are then made based on judgements by the fitter and feedback from the rider followed by further measurements, computations and adjustments as needed. The aim of this fit is to work towards the fastest sustainable riding position possible.
What's included?
- Detailed pre-fit assessment of rider anatomy, flexibility and stability. Recommendation of post fit exercises for strength and flexibility improvement.
- Assessment of rider position and movement using Retül motion capture, Leomo Inertial Measurement System, BioRacer Aero software and gebioMized saddle pressure mapping
