I seem to have brought together a collection of Suntour Sprint stuff - I love the pedals, and put them into use on several of my bikes, but also have a significant stash of NOS and lightly used drive train and other components. I think I have like 5 NOS RDs, including one of the rare black/gold ones (featured on one version of the Cannondale Black lightning), and multiples of other parts.
I really like the stuff, great form, great finish, great function, my favourite full Suntour group, from an era of cycling I draw many of my bikes from. A large part of this had to do with NOS Sprint bits being fairly commonly available at really attractive prices a few years ago - so I also have the satisfaction of knowing I snagged all of this stuff at a cost that's much more reasonable than the I'd have paid for contemporary components of equivalent quality (think Rivendell-equivalent NOS Sprint ratcheting shifters, $25 + shipping, etc.)
Now, once I actually get around to mounting a full group on a nice, appropriate North American or Japanese frame, I'll have ton of spares. Until then, I find myself somewhat irrationally pleased to come across these bits amongst the bins - sharp little marvels of form and function, not the absolute top-of-the line but a truly great group.
