Away a full days' ride yesterday, on the saddle for at least two hours each time before a break.
Fairly well locked-in to the seating position, way forward against the tank but no complaints of soreness.
Only stopped to explore a location or for refreshments, not stopping due to sore butt.
Will mention again that the increase in confidence due to lower position is a great bonus with this seat, I am not short ,178cm (5'10" in the old measurement) but to flat-foot the deck in most situations now is reassuring.
I recommend this seat.
