Hi all
I've used Brooks B17 saddles for a number of years, but now that I'm doing more distance (~100 miles a week including one ride a week in the 40 to 70 mile range), perineal numbness has become a concern. I got a C17 carved (all weather) to address the issue. The cutout worked great. No more perineal numbness!! However, the seat caused a different problem - soreness in the coccyx area. I never had this problem on a bicycle before. However I had struggled with it in the past with kayak seats, because of the elevated knees seating position in a kayak putting all the pressure there. I was dumbfounded to find I had gotten this issue on a bicycle, because I didn't think the seat would even press against an area that would cause it (BTW my bike has basically a touring layout with drop bars and seat about the same height as the bars - not an aggressive racing position but not an upright comfort position either).

Relative to the B17 the C17 has a more rounded shape and the swoop up in the back is also more pronounced. I assume one or the other of these attributes is causing my problem. I've been wondering if one of the other Cambriums (C13, C15, or C19) would work better. My sit bone width measures at about 120 to 125 mm, so I think in that regard I could handle a narrower saddle. Perhaps with a C13 being so much narrower I would sit further back on it and there would be much less pressure on the coccyx area? OR perhaps a C19 would provide a flatter surface to sit on so that the curved saddle shape wouldn't be pushing so deep into my crotch and therefore it would relieve pressure on the coccyx in that way? Anyone here have a similar issue that can offer any advice?
