I just got the B17 imperial last week, first ride was 15 miles adjusting tilt, still need to move nose a touch up, i slide forward a bit. My right sit bone was tender.

I proofide underside as directed before first ride and again a week later.

I kept the old selle gel on its seat post a got a new thompson for the brooks, going out Saturday, maybe 20 miles. Will adjust saddle forward - backwards and post height on next ride.
