A friend who has been using her Spinner Ascent bike religiously recently had a crank arm break off. She is having a heck of a time trying to find a replacement. I've never even heard of this model, although I suspect it is the "for home" version of the bikes that are offered on the spinning website. Does anyone know where I can tell her to look for a part? Does anyone here have a spare they'll sell me/her?

thanks!
