Does this actually mean I can use a SRAM Red BB30 crankset in my frame? If so, this means I can drop a ton of weight and improve shifting going to the NEW RED on my Racemaster.
How many drivers does a buggy have?
So let's just say I'm drivin' this buggy...
and if you fix your attitude you can ride along with me.
Their descriptions makes it sound like you can use a standard BB30 crank (ie. RED, FORCE) on a 68mm BSA frame. I understand that the Rotor 3D+ and "386" cranks have a longer spindle.
Sorry about the rant but I think it's really confusing, unnecessary, and misleading to market a crank as BB30 just because it can fit in a BB30 BB shell...what crank can't?
As far as those cups go who knows maybe the seller or manufacturere doesn't know any better.
I just wanted to confirm that it is my understanding that I can use
my traditional 68mm threaded road frame (BMC racemaster) and install a
SRAM Red BB30 crankset using your T30 BB?
Them-Thanks for the email.
You are correct. That is the exact type of application the T30 was designed for: BSA to BB30.
We ship internationally every day. Just click on the PayPal button and you're good to go. FYI, we now have Italian threaded versions but haven't updated our website.

Not trying to re-hash a debate that's been on here a number of times or tell anyone her they are wrong on this subject, not the reason for the post.
Thanks for the reply. Im a little confused. It had always been my understanding a BB30 crank (Red, Force,FSA) could not be adapted to BSA because of the spindle length is too short with the external cups.
However, with the added spindle length on cranks like Rotor 3d+ and BB386 cranks, they can use a BSA BB.
I want to use a SRAM Red bb30 crank. Just trying to clear up my confusion.
The shell on a BB30 bike is wider than BSA. The cups make up the difference.
I've never installed that exact combination with my own hands but this is the application they were designed for based on factory specs.
We would cover these as a warranty return if there was an issue.

A standard BB30 crankset like RED and others have a too narrow axle to fit a BSA threaded frame + two cups, there´s just not enough place.
The best solution is a modular crankset like Lightning which have spacers on the axle, or a MTB version of Sworks cranks on a road frame, they are wider.
I use Cannondale Hollowgram just because they are modular and no way a BSA 68 shell with cups will be at right width for a Hollowgram axle of 104mm, we are talking about use a 131mm axle, a SRM axle at 122 can MAY be used,a 128mm can be used, haven´t tested yet.
Take a look of my attached file.
