Introducing BB30 Option for Z1, Z2 and Z3
For 2009 we are excited to offer a BB30 option for our Z1, Z2 and Z3 frame sets. BB30 is a (relatively) new open standard, originally launched by Cannondale, that is threadless and uses a larger bore and therefore axle for the crank versus standard English-threaded bottom brackets. Benefits can include lighter overall combined weight, lower Q factor, increased stiffness as well as increased ankle clearance.
We have offered a similar sized option for both the ZIPP Vuma series as well as the THM crankset since 2006, so this concept is not necessarily “new” to us, but the BB30 spacing is a little different than the ZIPP or the THM. Crank options are now shipping from SRAM, FSA and others. The BB30 compatible bottom bracket is being offered as an option when a frame is ordered. The 68mm English threaded standard is still the standard on all our frames.
