    Wired SRM models

    I'm in the market for a used BSA-compatible SRM, and I have a couple of questions I was hoping you might answer.

    What crankarms are used in the crankset below?

    Looks to me like they might be rebranded hollowgram crankarms, but I can't really tell.

    Also, are hollowgram cranksets bb30-only?

    Thanks!

    those are 'SRM' crank arms, which was the only crankset available when the SRM system for came out. it wasn't until years later that SRM started working w/ other component companies (Shimano, SRAM, FSA, Campy) and building their system into other cranks. The are machined from billet aluminum and are not hollow.

    not sure what you mean by 'BSA' compatible as the crank doesn't care whether you bolt it to an English or Italian threaded frame and bottom bracket. there are 'cranks'...not 'english(BSA)' or 'italian' cranks.

    Thanks.

    To clarify, I am looking for a way to attach an SRM to my English threaded frame. As I understand, there are several types of SRM spiders, some of which (i.e. the early wired ones with bolt-on arms, and those sold with Shimano 7800 cranks) are assembled into crank sets which fit BSA-compatible bottom brackets.

    I say "BSA-compatible" because apparently some hollowgram cranksets can be used in English threaded frames with some effort.

    so what you need is any SRM using a standard Shimano Dura Ace crank, a SRAM GXP crank or the 24mm spindle (like SRAM & Shimano) FSA SRM. or a Campy SRM. you've got no shortage of cranks to chose from.
