Aren't that MTB crank arms?

Tragedy though, looked like such a nice hack.

BTW I'm quite sure these are the wider models that would fit:

Looks like road spider on MTB cranks, yeah. Maybe the other way round it'd work as the MTB cranks are a bit burlier than road ones. One of those things where unfortunately you need the parts in hand to know...

A guy in this thread has an interesting suggestion:

yes, it physically fits. the chain line will be a touch off. I think you may need to use one from the same spindle type tho..ie both bb30 or both gxp cranks.

loads of info here too:

I think it could be done, it's just that you have to buy the right parts or you're going to end up with bits that don't fit which you have to return or sell again. Also ideally you don't want to get stuck with SRAM's 120/80 BCD I suppose.

Edit: you could take a risk and file the lip off the spider I guess

Yeah interesting stuff, seen most of this. The MTB spider has a chainline that is 3mm wider/bigger. You could fix that with the early BB30 SRAM cranksets that have a 2,5mm smaller/shorter chainline..

So much to try out, so little time to do it all :)
