I would like to run an 8spd cassette, der, and shifter.oldfart said:If you just want to run an old 8 speed rear derailleur with a 9spd shifter and cassette, you don't need to do anything. The pulleys and cage will be slightly wider and there is a slight chance that the cage could be too close to the spokes in low gear.
If you are talking 8 spd cassette, I don't think you can convert a 9 spd shifter to 8 speed. With Campognolo road stuff you can convert between 9 and 10 speed with the purchase of the parts. Pretty sure SRAM don't sell those parts.
8 instead of 1? neaky:MMcG said:I have 8 speed on my TEd wojcik and 9 speed on the Surly right now - but I too am tempted to convert the SUrly to 8 speed.
Sorry, as I've done some reading today and talking I've come to realise a few things.BikeGeek said:Start over. What are you trying to accomplish?
Re-reading the first post it sounds as if you have 9-speed shifters and are wondering if an 8-speed derailleur will work with them. Is that right? If so, I think the answer is yes.
THats what I'm thinking about doing.....SuspectDevice said:What's your issue Stosh?
Just buy 8 speed X7 shifters and a medium x9 or xo rear deraileur.
See I'm pretty happy with SRAM...jacksonpt said:ok... let's see here... From what I know (which isn't always a lot, so take this with a grain of salt)...
The shifters, chain, and cassette are what determine a bike to be x # of speeds. The cassette is obvious as it only has 8 or 9 or whatever number of cogs. A 9speed chain is narrower than an 8speed chain to better fit with the additional cog in a 9speed cassette (though I've heard some people mixing chains with decent performance). The rear shifter will have either 8 or 9 clicks depending. In theory it would be possible to setup the derailleur so you could use 9speed shifters with an 8speed cassette (limiting screws primarily), then you'd have to remember not to click into that first/last click on the shifter. In terms of speeds, a der is a der... makes no difference.
Now... short/med/long cage derailleurs... If you're running a full cassette and 3 chainrings, I'm almost certain you can't get away with a short cage der. If you are only running 2 chainrings up front, either no granny or a bash guard, then a short cager should be fine.
As far as your options go... you can keep your 9speed triggers, buy a new der and run a 9speed setup (which is what you want to avoid, correct?). You can keep your triggers, buy a new der (to replace the broken one) and an 8speed cassette/chain and setup your triggers for 8speed use. It will work, but I don't think it meets your "easy to setup/use/maintain" requirement. Or you can buy 8speed triggers (or grip shifters if that's your thing), cassette, and chain (either sram or shimano) and have at it.
If it were up to me, I'd search around for some used 8 speed XT/XTR triggers. 8speed cassettes and chains are still very easy to find new, so that shouldn't be an issue.
if stosh isn t interested i am.. pods only yeah ???mattv2099 said:I have some never used 8-speed Shimano XT shifters I was going to slap up on Ebay within the next week... let me know if you want them I can slap them up like today with a buy it now price or something.
Yepstosh said:The last comment you made about SRAM was "I wouldn't have spent all the money on them if I was to do it again" meaning it wasn't worth the extra $ to buy SRAM. Is this still your feeling?
