I was hoping the newer generation models might fit a fatter tire.
Nope , as mentioned Green speed is about it.. The company is also the wholesale distributing importer for Australia
37 to 40 you only gain , (math) 3mm.. is the search and expense of trying to get green speed tires worth it? only you can decide...
I have 406-47 tires on my bike Friday pocket Llama , its a bit more cumbersome to fold.. ..
