I've been looking. Early Rockhoppers actually came equipped with Deore XT Deerhead groups. The last couple on ebay have gone for several hundred. My local, Cleveland OH, CL has really inflated prices.
I was more interested in what size BB I would need to get a decent chainline. Stock they used a 122mm. I know as a SS it wouldn't need anything that big.
