I have considered a bike fit but I don't suffer any pain other than on my backside.
Over the years I have tuned my position to practically eliminate hand numbness, neck and back pain. I still get a bit of sore neck when I do a particularly long ride but I think that is simply a matter of more training.
A few years ago I was quite happy with brooks saddles but then I spent a year and a bit where a did hardly any riding and after that my Brooks Swallow and Team Pro felt uncomfortable after 20 miles. I still have a B17 that is really comfortable for 20 miles.
The saddles I have been riding for the last 2 years are Specialised Phenom Pro which is good for up to 35 miles. I then bought a Fizik Antares which I liked but I felt I needed a little bit more padding so I recently got the more developed brother
and we are not getting along too well.
No soreness with any of the saddles, simply painful around the sit bones area.
Would a bike fit help? I'm not sure.
