I just stepped off 32 miles on a brand new Brooks Swallow Select on my road bike.
I thought we'd be breaking each other in, but the saddle was 100% invisible, except on bumps, where I could feel it giving way.
my other two bikes, semi-upright and upright have B17 Select and they're equally invisible.
This is in loose nylon shorts or knickers and merino boxers - no chamois or diaper. The no chamois or diaper with the cooling of a Brooks saddle prevents chaffing on the longest hottest summer ride.
Weather permitting, I try to ride 100-150 mi/wk.
The trick is to match the right saddle shape with your riding position first, and sit bone width next.
If your bike is upright, you're in luck - you can ride a Brooks B67 and won't know it's there.
This is a 10,000 mi B17 Select
