Dagnabbit I didn't notice that, looks like they're some weird size that even Sheldon doesn't list - glad you're paying attention velo.velomaniac":3v25okqz said:Hud on, just noticed, 37-609, what size wheels are those :?
700c are 622mm and 27" are 630mm so whats 609mm, some weird continental size......
And don't go big wheel just because, much more interesting if we all turn up with a broad variety of machinery.
Aha! I give you the Kenda K161 - ISO numbers look right.
