"They look like normal bikes with 26" wheels!"

Nothing really. I always preferred how a singlespeed drivetrain dealt with muddy offroad conditions and general neglect, so when I became too puny to SS it anymore, decided to give internal gears a try

I'm not going to become a gearbox advocate, as they're certainly not for everybody or all types of bikes, but I like them, and if the Pinion gives me as little hassle as the Rohloff has, I'll likely consider it for any future bikes too
