SRM are no longer making or selling the replacement crank arms for the 7900 model.

I saw a while ago Adam Hansen riding a custom SRM with custom crank arms (I think they are lightning). Is it possible to buy aftermarket crank arms that will fit on a 7900 SRM power meter?

Alternitivly has anyone managed to machine some 7800 arms or others to fit an SRM?

I think the answer depends on the spline pattern of the DA 7900 SRM. I would suggest a call or email to SRM, as they tend to be very helpful with issues like this.

Definitely make contacting SRM in Co Springs your first move. They will be able to offer you the best advise.

What crank length are you needing?
