STX Derailleur on 9 speed cassette
I happened to acquire a Shimano LX 9 speed cassette and have gotten the
upgrade bug for my 1998 Trek 6000 mountain bike. Here's the current rear setup on my bike: 7 speed cassette on 7 speed Freehub Shimano Parralax hub STX rear derailleur 7 speed shifter (Alivio or Acera, I think) Now, as I see it, there's two options for me: 1) I can do the "8 of 9 on 7" upgrade talked about at Sheldon Brown's site. This would require me to swap out my current shifter and cassette, however, I could keep my freehub and avoid the redishing. For an explanation, see http://www.sheldonbrown.com/k7.html#up7 2) My other option is to replace the Freehub and put all of the 9 speed cassette on. This would require me to purchase a Freehub at least, and redish the wheel. I am wondering if my STX derailleur will have enough reach for the 32T of the new cassette. Either situation is going to require me to buy a new chain, but the less I have to purchase, the happier my wife will be. I already have the rear shifter, as my front shifter broke last year and the only shifters I could find in a pinch were new LX shifters. What are your suggestions and thought on these two options? Have many folks tried the "8 of 9 on 7," and are they happy with it? Thanks in advance, Brad Kattelmann http://brainfuzz.net |

I am wondering if my STX derailleur will have enough reach for the 32T of the new cassette. Sure. Either situation is going to require me to buy a new chain, but the less I have to purchase, the happier my wife will be. I already have the rear shifter, as my front shifter broke last year and the only shifters I could find in a pinch were new LX shifters. That's confusing, 'cause you say up above that you've got a 7-speed shifter. What are your suggestions and thought on these two options? Have many folks tried the "8 of 9 on 7," and are they happy with it? Either of these will involve buying a 9-speed chain, so the only difference is the Freehub body. If money is tight, just go for option 1 in the short term, then buy the new body when finances permit.

I have tried the 8 from 9 cassette on the freehub and frame for size, it fits OK so I can't see any more problems occuring. I just need to get a cassette and a chain. I am making a custom 13-32 cassette, I have a 11-32 just need a 13-25 to get the smaller sprockets. I am already using a 9 speed Deore XT rear mech with a six speed cassette, I have some 9 speed levers waiting to be fitted. Lack of funds is delaying me right now, currently I am out of work, loads of time to ride but no money ! As me again in 2 months. |

STX Derailleur on 9 speed cassette
Well, I changed over the cassette and it went quite painlessly. I
haven't yet had a chance to go by the LBS, so no chain yet. The STX derailleur has plenty of reach it would seem. I had to adjust the H screw so it lined up with the 11t gear, but otherwise the conversion was flawless. I meant freehub body in my earlier post, but somehow forgot the word. Also, in my last post, I meant, I had an extra rear shifter that I hadn't installed. I didn't want to install a 9 speed shifter on a 7 speed cassette because of the difference in spacing. Now, I have a 9 speed shifter installed with 8 gears and the derailleur adjustment screws limiting the shifter.

Thanks in advance, Brad Kattelmann http://brainfuzz.net I'm running 8 of 9 on an old 7 speed STX freehub no problem...and with a "7 speed" STX crankset, front derailer, and rear derailer to boot! I had a few 12 tooth bottom sprockets laying around from road cassette alterations so I used that as the bottom of an 11-32 cassette. Kyle |
