I recently acquired two handlebar sets with original Suntour Thumb shifters on them. They are really cool because you can interchange the two sets simply by removing the finger screw from the top and replacing it on the other handlebars. Pictures when they are available.

I've already had one mechanic down at Waterfront Workshops inquire about them...seems they may be collectible...although, frankly, not as useful as those early 90s Shimano Deore LX shifters--I just discovered that it would cost over $300 to replace those on my 1991 Specialized Rockhopper...and that is for components that don't have an index to friction toggle switch. Man, they don't make them like they used to...now all the shifters are indexed pretty much on mountain bikes and hybrids so the components are not as versatile as they used to be.

Looks like most kids growing up nowadays don't even know much about friction shifters. In any case, since I can put an 8 or 9 cog Freehub on my Rockhopper's Deore LX hub and just switch to friction shifting if my index won't synch...I'm going to keep my old shifters for sure. And if you have older Deore LX component bikes, I advise you not to part with them...I mean, do part them out to your other bikes but don't sell them! This stuff is in demand and there is a reason for it...this stuff works and it works with modern and old equipment. If you buy new equipment, you have to shell out $200+ just for the shifter/brake integrated assembly which isn't as good as this older stuff!
