medical warnings aside, which Im not able to comment on , due to lack of expertise.
67, for the earlier down in the drop bars riding posture era
I was using ; a Brooks Team Professional, a selle Italia Turbo and a selle San Marco Rolls.
now sitting up more, the saddle has gotten wider in the back, and in this wet most of the year climate
I have favored the Fizik Vitesse. as a unisex/womens saddle Black, steel rail, seems harder to find these days.
but yea sitting for :45 a bit uncomfortable? stop stand over the bike off the saddle , take a drink of water.
then start again.. .. took long tours on that un padded leather Brooks , made a number of Pub stops along the way.
