    Middleburn crank arms/ W.I. ring compatibility?

    I was looking at some Middleburn cranks but their SS rings sizes are limited. Would the splines of a Middleburn crank mate to the White Industries SS rings?

    I asked Doug White if the two cranks use the same interface. He had no idea and he designed the WI crank. So I would guess it is highly unlikely they are interchangeable.

    The trouble with common sense is it is no longer common

    Pretty sure you can be Middleburns with a spider.

    I think you can get a four bolt spider for the Middleburns.

    Better yet, they offer 5-bolt spiders. Just say NO to 4-bolt cranks.

    I too was wandering if the Middleburn spiders would fit the ENO's. I'd like to be able to run steel (Surly) rings on them and be able to change rings without pulling the cranks.

    I'm with you on the 5 bolt spider Shiggy. I was thinking of using some WI rings I have. This will be a 1x9 set-up, now I'm looking for a 38T SS ring to match their 5 bolt CD (BCD 94mm) or the 5 bolt ATB (BCD 110). Sorry, I know I just took this OT for the SS forum but thought my fellow SSer's would help with my first question. Thanks, opinions welcome.

    I would get the 110 BCD spider and a Surly SS ring.

    Chainring: The ENO crank is designed with a proprietary spline that mates to White Industries chainrings.

    http://whiteind.com/Tech_Info/INSTRUCTIONS/cranks.htm

    The inner ring attaches to either RS-7 or RS-8 cranks using our exclusive Sweet Torque™ interface.

    Sweet-TorqueTM
    Modular crank system…
    Our modular crank system allows the crank to detach from the spider. Since its introduction with the first RS cranks it has been adopted by a range of other crank manufacturers.
