Joseph Kuosac designed this suspension block for use in high-speed applications where every pedal stroke counts. It is even firmer than the Brompton stock-standard "Firm" block, which means even more power conservation on long flat breakaways. 

It's a great pairing with the Titanium seatpost, which provides enough suspension to make the ride comfortable without needing additional cushion.
