OK, as usual, a bike forum used for support tends to turn on the rider LOL
I have had a fit and the fit is fine. I never said I am having problems with the fit. I said can a bike be overly stiff - asking other F8 owners or fellow riders - given the love hate relationship Pinarello have with riders.
I like stiff bikes. My legacy is S-works tarmac, evo, dogma, s3 etc. I like fast flat back bikes as I have tried endurance geo and my boby geo works better on a race bike based on retul data. I am 45, I have ridden 200 miles with 11,000 feet of up this week and I like riding hard, fast and full gas when the road currys favour. What goes up must come down and the F8 is an insanely good descending bike. I run 23mm based on the fact the 23mm is 25mm in my wheelset up and it works. But, as per my original post, the Dogma is a stiff frame. When I feel 25 or 28mm tyres are required in my life I will choose a bike to suit. But as someone in a bike shop is likely saying as we speak "i aint no professional".
There is another small issue which rises up here and that is when I was 17, I had major surgery on my left hand after cutting through the top of my left hand when I was at work, I lost the use of two fingers and my thumb for 6 months and had a five hour operation on the hand. I suspect that this is now part of the issue - nerve damage loss of feeling coming back later in life. But seriously, thanks for all the input and advice and what not. Keep on truckin' !
