Please note: We cannot determine what the appropriate length bottom bracket is. There is no way to determine it except through testing one and making corrections. Each bike has a unique setup - chainstay shape, front derailleur location, etc. 





Note: We can't determine how long of a bottom bracket spindle you require. It's dependent on your frame, derailleur's swing, etc. The only way is trying to determine it experimentally. It includes a 124mm wide spindled bottom bracket. It may or not be the right length for your application.
