It is important to trim the end of the tube neatly.
- Page 11 In order to move the bottom bracket tube your specialist dealer has to adjust the chain length. By default the Street Machine GT co- mes with a very long chain so that the adjust- ment range of the bicycle can be fully used wi- thout the need to lengthen the chain.
