I put a Brooks B-17 on my new Specialized Hardrock Sport. The stock saddle was actually pretty good after dialing in, but the Brooks is BLISS! I decided to try a Brooks when I realized that the posture is not all that different from my "Frankenbike" commuter (I have a B-17 Narrow on my commuter road bike).
The quick release Topeak baggie bracket didn't fit the B-17 so I had to fabricate a different one. When I was tapping holes in the new bracket, I was surprised to find that the allen head machine screws were 10X32 and not metric. Are they made in USA?
