Why use an EBB (Eccentric Bottom Bracket) on a single speed?
The traditional method of tensioning a chain on a single speed is through the use of track fork ends. The slotted design allows the rear wheel to be pulled back until the proper chain tension is achieved, then the rear wheel is tightened. This design has been used for decades, and is still vastly used today. However, the design does present some potential issues, especially with the use of modern disc brakes. Enter the Eccentric Bottom Bracket (EBB). The EBB design allows the use of vertical dropouts on your frame. It is actually the use of these vertical dropouts that provides the key benefits inherent with an EBB-equipped frame, such as: • Elimination of brake pad alignment issues when adjusting chain tension (most critical with disc brakes, but also applicable to linear-pull brakes). • Elimination of the potential for wheel slip under load, especially when using a quick-release rear skewer. • Quick-release skewers allow for easier wheel removal, whether for maintenance or while on t
