The Brooks C17 is aesthetically pleasing on the Brompton giving a very classic english look, but really not the right saddles for me. I really like the Boira Duopower, the no-nose design reducing pressure in the groin area giving a more comfortable long ride, But it’s sold out everywhere.
I ended up going back to Selle Italia, an Italian brand and they make very good saddles primary very popular for road bikers. Wiggle carry a good range of Selle Italia saddles and I found the Novus Boost Superflow at a super good price.
The quality of the saddle is really astonishing, weight at 182g comparing to Brooks c17 at 464g still give a very sturdy feel. I like the short nose not putting too much pressure on the groin making long ride comfortable and enjoyable.
The white color looks good on water blue as well, personally I preferred it over the c17.
To the next upgrade, ride safe, have fun.
