hello,
as the title says,is this possible?
ive looked into it my self and seems so.i understand the inherant risk that running a bb30 in a bb92 will have a very thin bearing,which could would wear out quicker.
E13 make this:

which is a bb92+ adaptor which presses into the bb92 and allow a e13 axles to fit which is 30mm)
would this allow ANY bb30 crank to be used them or exclusivley the e13?
many thanks

Although bb30 and E13 cranks both use a 30mm axle,BB30 uses a nominal 68mm axle length whilst the E13's use 90mm axle length (which is why you can use external cups with them on a 68/73mm bb shell).
So basically,no.You can't use any bb30 chainset (as the axle is too short).
ok this is usefull to know,ive also found these puppys:

would these be a better bet?
should have said,swaying towards rotor cranks at pressent,but more curious overall compatability.
" this adapter bottom bracket is designed for use with BB92 bottom bracket shells with a press-fit ID of 41mm. Since BB92 bottom bracket shells are 92mm wide, [b]you must use a BB30 crankset with a long enough spindle, such as the Rotor 3D+ crankset[/b]"
You could use an FSA 386evo chainset because that has a 90mm axle....but they don't make an mtb one yet 🙁
