Triathlon & Time Trial Fitting

A Triathlon and Time Trial fitting has unique fit-related challenges for the athlete and is a delicate balance to optimise power, aerodynamics, function and comfort.

Fitting a rider for an Ironman triathlon, a ten mile Time Trial or a pursuit race in the velodrome event is inherently difficult and should only ever be undertaken by the most skilled and experienced fitters. A good understanding of a rider's physiology and performance level is key to the fit and also equipment and helmet selection.

Up to 80% of total drag is attributable to the rider, so it's right to focus here for the biggest slippery gains.

Depending on the particular event and duration your position will be adjusted accordingly; with attention paid to equipment and helmet selection plus a focus on posture and head position to generate power and reduce drag. Our fitters have worked with GB pursuit riders, World Tour time triallists and GB Age Group Triathletes all looking for that place on the bike that feels like home.

The Triathlon and TT fits are at 9:30am Tuesday to Friday to allow enough time for our mechanic to make any changes to the bike during the session.

Bioracer Aero Virtual Wind Tunnel


Using Bioracer's new software we can optimise your aero position and give you live feedback on watts saved and time gained in your event. We will work with you to find an aero position that is sustainable and that also enables you to generate as much power as possible for the duration of your event.

Bioracer Aero is used by: British Cycling, British Triathlon and World Tour teams Team Sky, Michaelton Scott and UAE.

The Cyclefit Triathlon or Time Trial fitting will:

  • Reduce frontal surface area and optimise aerodynamic shape
  • Fine tune posture, head and helmet position
  • Maintain good breathing function
  • Optimise knee-extension
  • Maintain pelvic stability
  • Adjust crank-length
  • Maintain open-hip with forward rotation
  • Calibrate cleat-position
  • Maintain good pedalling dynamics (especially through the top of the pedal stroke)
  • Use a position that is appropriate for athlete's: flexibility, injury-history, aspiration, event-duration
  • Advice on equipment and bike selection

Junior World Time Trial Champion Tom Pidcock chooses Cyclefit to dial his position.

What our clients say

  • "Thanks very much Phil. Did an 80 mile sportive yesterday on the road bike - perfect set up thanks; I've never been so comfortable, and no after effects! Cheers, Ian "

    Ian T.

    Time-Triallist (70+)

  • "Thanks very much for consultation last week - since I saw you I do not have anything like the same amount of pain I was experiencing previously. I am so much more at ease with my new positioning and my posture feels right now."

    Jane B
  • "Hey Julian and Phil, I hope you are both well. I just completed a 21 hour week on my new 165mm cranks and I am in love. They feel so so great! Thank you for all your help. I’ve never felt so comfortable on my bike before. All the best, Hannah"

    Hannah Barnes

    National Champion / Professional Bike Rider

  • "A great service, full of personal touches as well as the "harder" scientific analysis of my position on the bike, which was also excellent. I feel more planted on the bike now, and came away with some really useful feedback from the session."

    Ed H

    London Dynamo Rider

  • "I tried the shorter cranks today and I like them - it feels like it's less stress for the back and it seems easier to ride higher cadence. In the end I had a good Tour with no back problems. Thanks for your help!"
