Woodlands, 60 km. Shimano used to be ubiquitous. Not anymore. Even neighbourhood bike shops carry KMC chains. The shops that deal with Shimano have no stock. The fifth shop I go to has SRAM, then directs me to the nearest Shimano dealer, which has the chain for almost half the price of a KMC chain. And that's why it's far easier to find KMC chains: it costs more and so has a higher margin?
How times have changed: Shimano chains used to be ubiquitous.
As Bob Dylan put it, "the times they are a-changin'".
