EVOBIKES ONLINE STORE Posted October 30, 2013 Posted October 30, 2013 'Rotor's BSA30 bottom bracket allows the installation of our 3D+ BB30 cranks into a standard, threaded bottom-bracket.' I would just wonder about that statement for that converter but that's just me Statement is 100% correct. Bearings are now OUTBOARD (ie not in BB cup) there fore a 30mm axle easily fits through a BSA BB-cup... The BB30 convertor basically screws into a BSA BB cup.

Remember you basically have 2 extra bearing width "spacers"on the outside of the BB-shell...
JA-Q001 Posted October 30, 2013 Posted October 30, 2013 (edited) Statement is 100% correct. Bearings are now OUTBOARD (ie not in BB cup) there fore a 30mm axle easily fits through a BSA BB-cup... The BB30 convertor basically screws into a BSA BB cup. Still wrong, A BB30 has an axle length of 680mm, your standard threaded BB shell is also 68mm. You cannot fit a BB30 into a standard BB shell, no adapter for this. (As you mentioned about axle length) The adapter you are selling is in essence for an evo BB386, these have longer axles (86mm hence the 86 in 386). All of the rotor cranks have 860mm axles, they use spacers/lock rings to make it fit a BB30. Cervelo is the company that started now with the evo BB386.

(Edit, sorry typing fast before I go home) Read my posts again think there might be confusion - if your AXLE lengths are long enough it will fit INTO a BSA BB with a BB30 adapter - which is what the OP asked. So if your BB30 crank has a normal axle it won't fit. If however you have a BB30 Crankset with a longer axle(ROTOR,FSA etc )they will fit into a BSA BB using a BB30 convertor...
