I have been riding a B17 large rivet saddle for the past 10 years on my commuter weekender. Made the switch to the C17 all weather recently and am so happy with the decision. No break in period, ready to ride and super comfy.
The original was far more expensive and while it was instantly ready to ride, no break in required, the cloth didnt hold up with time. Within a couple months the edge on the side was torn. I expect that but not that quickly. This new one seems tighter in fabric dept...if that can make sense, but still maintain the brooks iconic look and hopefully durability. I usually bike to and from bike station within 20 min of my house and it looks way better than my original C17 within timeframe using it.
