Cool! Do you think that a center lock brake disk would fit to those same splines where roller brake set sits? I like your knife by the way, it looks like Finnish puukko, the blade and handle shape.
My Batavus 2004 personal bike uses those roller brakes. How long do they normally last? Although twenty years old when I bought it in 2022 the owner told me it had spent the last fifteen years in her garage. I replaced the tyres & bought the special roller brake grease required.
A very long time for sure. Been riding mine for at least 15.000 km. Had them since new. Does not have to do anything to them other than having the shop put some grease into the chamber. Never getting another brake type.
