The Team Pro is narrower than the B-17, I think. I have pretty narrow sitbones for a woman, and it would be my favorite saddle if it would work on my road bike. (It doesn't have enough forward/aft adjustability so I can't get it positioned right even with a seatpost with lots of setback.) For comparison: a Terry Butterfly is too wide for me; I ride a Fizik Vitesse, which is also fairly narrow.
