Using an Eccentric BB (www.firstcompo...) to adjust chain tension and bottom bracket height.
If you have an English Threaded BSA bottom bracket setup, you will be good to go straight away with this model. The set fits just like any other BSA 24 threads per inch unit.
Whereas you normally loosen and adjust your single speed chain tension through loosening the wheel nuts. Once the eccentric BB is fitted though there will be no need for this. The set comes with different sized spacers and a wavy washer along with a dedicated tool for installation and removal. You use a 2mm allen wrench to loosen the three bolts securing the outer casing. Rotating the outer casing allows tension and height adjustment. Once you have the right tension or BB height, simply tighten the 3 casing bolts on either side. The procedure with a mountain bike is similar. You adjust the bottom bracket height in the same way. Loosen the casing bolts. Rotate both sides to the right point. Retighten the casing bolts.
