I Had terrible problems with numb crotch and sore crotch, tried more padded saddles, did not work, tried different racing saddles, sella, fizik arione, better but still a problem for long rides got a brooks professional and the problem was solved day one, no break in period needed. now, I have a brooks sparrow on my super bike and put my brooks professional on my stand by. the sparrow is magnificent, again no break in needed, comfortable day 1. I will never usre another saddle. brooks is the best.
