The key for any bike fit is the saddle. If you’re not comfortable and always moving to find comfort – then it’s the wrong fit and type. Time trial saddles are made for sitting in aero. So, finding one that fits your body properly cannot be underestimated.
Next is the height of your seat. You want to have your heal parallel to the floor with a slight bend in your knee at the most extended part of your pedal stroke. If you have anterior knee pain, it’s likely due to a seat that is too low.
Front end setups depend on many factors, from flexibility to torso length. My recommendation is to find something that is comfortable and slowly tweak it with a bike fitter. Be sure to find someone that is experienced in triathlon.
Finding the right bike position is about as individual as they come. Don’t be fooled by the ‘one angle fits all’ approach or the bike fit that your ‘fitter’ has provided you. Making adjustments is part of the process.
Finding comfort on a bike, especially for an Ironman distance event takes time. You have to find that balance point – where you’re strong and powerful, yet comfortable enough to maintain an aerodynamic position. Don’t be afraid to experiment with the setup.
1) Get a bike fit by a fitter who is experienced in triathlon.
2) Ask questions and learn about how to do small adjustments.
3) Don’t be afraid of making adjustments for comfort.
4) Never jump into a long ride expecting the fit to be perfect.
5) Take comfort over any ‘aerodynamic’ setup, especially in an Ironman race.
