Hi All. I've just bought a slightly used Incline Cruz 7 bike - 700c wheels, front suspension, shaft drive with 7-speed Shimano Nexus hub. (Presumably very similar to the Dynamic brand - the shaft part is made by Sussex. Weighs about 35 pounds BTW.) The friction and roughness in the drive train seemed excessive, so I added grease to the hole under the bottom bracket, and to the bevel gear in the rear (with the plastic cover removed). It's significantly better now, but there is still some roughness. If it was a chain-driven bike I'd say that bottom bracket feels like it's over-tight and perhaps undergreased. But for this bike, perhaps it's normal? If I wanted to check and adjust and grease the bottom bracket bearings, how would I take it apart? Does the grease added to the bottom bracket bevel gearing also reach the axle bearings? How much grease should I add to that hole? (I added about 10 cubic centimeters, using a syringe.) Thanks for any advice.
