They are however tailored for different handlebar/saddle positions. See, your ischium/pubic arch tapers to the front of your body. This means that when in an upright position, you will sit on a wider part of your sit bones, therefore you'll need a wider saddle (e.g. B17)
If you prefer a more aerodynamic/racier position your ischium/pubic arch will tilt to the front, causing you to sit on a narrower section, requiring a narrower saddle. (E.g. Swift)
Yes, quite correct, Swifty. Actually, that's what I was saying, but in a different way. The fact that a 17 is built for the widest range of riders, but conforms to the differences
within that range is what I meant.
Different riding styles require different Brooks models for best comfort and efficiency.
