Bike fit question- weight balance on bike

My 2 pennies about fit:

  1. The various computer/video systems available are potentially useful, but beware of a fitter who is simply trying to move parts around to get you into pre-determined angles. Any decent fitter will have an ‘eye’, and will be asking your for your bio-feedback. An example; 2/3 fits I have had have put the saddle too high, even though the numbers and angles are textbook. I know this because if I put it at ‘the number’ I get saddle discomfort fairly quickly and a marked R/L power imbalance. If I drop it 4-5mm, both of those disappear.

  2. As noted above, there isn’t any one definitive fit. There is a range. I would beware any fitter who is too prescriptive.

  3. I would ideally go and see an independent bike fitter - i.e. one who doesn’t sell bikes/frames. That way, you know they don’t have a horse in the race.

  4. Fit can’t compensate for all problems. For example, if you have hugely under-active glutes and abs, a fit probably won’t relieve the back pain you have [hypothetical example, obviously]. Just be aware it’s not magic.

Having said all this, a good bike fit and consistent adherence to a few well-chosen mobility or strength exercises can dramatically increase your comfort and power, and in pretty short order.

Good luck!

Edit: and as an example…
