Really like Accushift housing, and I have a dwindling stash of it, enough left for one more bike. Seeing that I do not use indexed shifting on any of my bikes, and have always used it on the wife and kids bikes, it should be around for a few more years. My old friend Ray had the triple wheeled rear derailleur set up on a 4 ringed front end. He used it on his commuter bike, a 1986 Miyata Terrra Runner. Crazy gear range, and it worked. The front shifting was tough for the Mountech front der. but worked well for what it was, except when it became iced up in the winter. Truly a great der. design both front and rear. I still use a Mountech front on my commuter bike. Probably the best shifting front der. I have ever had the pleasure of using.
