Rolloff oil change; Santos
Item 2 Bicycles-Gears:
* the Rolloff gear box requires oil change every 5000 km, not already after 1000 km.
* Santos is a high-end Dutch bike brand, not German! The top in trekking bikes.
Speaking of Dutch, the Koga-Miyata brand has been renamed Koga.
By the way... very nice site.
