[Big Al]

Will x type diabolus cranks with bash gaurd fit on a demo 9?
What is the average retail price for the cranks in the Vancouver area?

They will fit, that is my setup.

I think they go for around $400 ca from Canadian shops and a little cheaper from Canadian online stores like Bikeroom. In the US they can be had for $266 us w/ bb, 2 rings and bash from the online store, Bikeman.
