Query: Nice upgrade

Upgraded the kid's old Huffy mtn bike with this new deraileur. Shifting now is much smoother than the rusted junk that came with it. Just had to fine tune the adjustments with the cassette and was good to go. A great value for the price and hard to find spare parts at your local bike shop. If you can find the parts at all these days on the shelf.
