I currently have Shimano Tiagra brakes. I am wanting to replace the stock Shimano pads with Kool Stop pads. On Kool Stop's website I do not see anything for Shimano other then 'Dura Type'. The Tiagra brake pads are not cartridge type brake pads. So, do I need to buy the Dura Road Holders and the Dura Type Brake pads or I am missing something entirely?
