Well I've done a few rides not any particularly long ones as I've not had the chance so the longest so far is 25 miles
No pain or discomfort whatsoever, I was a little sceptical about having a fit as I couldn't see how it would make such a difference, but the difference for me is massive,
If someone is fairly comfortable anyway then they may not see the massive gains that I've seen as I was so damn uncomfortable but I do now believe that if your position can be improved even slightly you will see a gain
Again I've not done any ride of great distance but overall my average speed is up by almost 3mph which you will probably agree is Hugh, I used to average around 12.2mph on any ride over 15 miles, I could sometimes manage 14mph but I would almost kill myself to achieve that, I'm now averaging 15mph fairly easily and over 18mph on shorter distances
Very very happy as the gains were literally overnight so now I can concentrate on getting fitter and faster
I will report back when I've done a 40+ miler
