| Component Notes | The Chameleon.4 uses an eccentric bottom bracket (E.B.B.) to adjust chain tension for single speed use. The E.B.B. is a simple wedge design, which requires little or no maintenance once setup correctly. If using a front derailleur, you can choose to have the E.B.B. at the 6 o’clock or 12 o’clock for different bb heights. It is best to use one of these positions for proper alignment with the front derailleur. When setting up the bike as a single speed, you can also choose between a higher and lower bb height. The advantages of this system over traditional horizontal dropouts are: perfect disk brake positioning, easy “set and forget” chain adjustment, and a consistent wheelbase length so your handling never changes.
