spear Posted October 30, 2013 Posted October 30, 2013 Normal BB to convert to BB30 so basically 54mm shell to BB30 Dose any one know where i can get this adaptor?
NotSoBigBen Posted October 30, 2013 Posted October 30, 2013 Is that even possible? I would imagine the other way round no problem but physically 'Normal' to 'BB30' would not fit .... I may be wrong but thats highly unlikely
rock Posted October 30, 2013 Posted October 30, 2013 isnt a BB30 shell bigger than a normal threaded BB shell? think you can only do it the other way round. check herehttp://problemsolversbike.com/products/category/bottom_bracket bb's explained http://problemsolversbike.com/files/tech/Bottom_Bracket_Standards_Reference.pdf
Bike Mob Posted October 30, 2013 Posted October 30, 2013 Threaded BB to BB30 look on Evo bikes for the rotor BB that solves your problem
rock Posted October 30, 2013 Posted October 30, 2013 the mention of a 54mm shell is throwing me......
Eldron Posted October 30, 2013 Posted October 30, 2013 BB30 axle diameter is 30mm. Normal is 24mm. Not sure it can be done - nothing I've seen anyway... BB30 to normal - no worries - plenty of adaptors/inserts/fittings etc to choose from.
spear Posted October 30, 2013 Author Posted October 30, 2013 normal = 54mmBB30 = 30mm There has been an adaptor out i just cant remember the brand and where i saw it so thought i ll ask u guys It is a very thin adaptor
Bike Mob Posted October 30, 2013 Posted October 30, 2013 the mention of a 54mm shell is throwing me...... I think He means BSA 24mm

NotSoBigBen Posted October 30, 2013 Posted October 30, 2013 http://www.evobikes....om-bracket.html '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
Eldron Posted October 30, 2013 Posted October 30, 2013 normal = 54mmBB30 = 30mm There has been an adaptor out i just cant remember the brand and where i saw it so thought i ll ask u guysIt is a very thin adaptor I think you're confusing shell diameter and axle diameter... A "normal/english/gxp/ISO/bsa BB has an inner shell diameter of 34mm (axle dia 24mm). BB30 is 42mm (BB30 axle diamter is 30mm). I don't know of any BB that has a 54mm shell diameter....
Eldron Posted October 30, 2013 Posted October 30, 2013 http://www.evobikes....om-bracket.html Wow. Haven't seen these before. Nice! I wondered when somebody would start making them. Thanks for the info.
