FAQ:

Q: How do you adjust an eccentric bottom bracket?

A: pull/press the cups into the shell similar to a press fit model. The specific bottom bracket you intend to use then screws into the eccentric bottom bracket unit. The eccentric effect (chain tensioning or BB height) comes through loosening the bolts, then rotating the unit containing the bottom bracket as a whole.

Q: Is top reinforcement required in eccentric footing?

A: Top reinforcement is needed in isolated footing majorly for two reasons. 1) Due to negative pressure under some or whole part of footing. In part of footing where there is positive pressure, the footing is in complete contact with soil and tension is in bottom side of footing.

Q: What are bottom bracket sizes?

A: – Bottom bracket measurements are always taken in millimeters. The most common sizes for the width of the shell are 68 mm and 73 mm. – You can use a ruler instead of calipers if you prefer. It’s easier to get a precise measurement with calipers, though. … – You can do this with the bracket installed on the bike or measure the bracket separately. …

Q: What is a road bike bottom bracket?

A: Your bottom bracket is that hollow bit at the bottom of the frame into which the bike’s cranks fit, to allow you to pedal. There’ll be an axle in there, which turns in a pair of bearings: one on the right-hand, drive side of the bike, the other on the left-hand non-drive side.
