Which 9-Speed Cassette, chain, and should I do the rings also?
I'm switching my snow bike/beater from 8-speed to 9-speed. I don't
want to spend a lot of money on this, but hear bad things about the nashbar & performance house brand cassettes. So, I'm going to have to spend over $20 on the cassette. O.K. How much more? The Shimano M580 looks like a nice unit, but it's around $50. I'd like to avoid spending that. The SRAM PG-950 is mighty tempting @ $30. Then again, the PG-970 The Shimano Nexave & Deore are both $32. How do they compare to each other & the PG-950. Finally, the SRAM PG-970 looks good @ $40. Is it worth the extra $10 over the 950? If I get to spending $40 on this would I be notably better off spending the $50 on the M580?* The chain: I'd like to spend under $20. Shimano or KMC? The place I'll be ordering from has both in stock. They don't have any SRAM chains, and I don't want to spend over $20 on a chain for this particular bike. Still, I hear great things about powerlinks & the SRAM chains. Am I really missing the boat if I don't go SRAM w/ the chain? I could buy one locally, but it'd be over 150% of my target price. Finally, the chainrings. This is a pawn-shop bike that until recently was on it's original grips (though worn out) and rims (not worn out). That's the best indicator to mileage I have. Everyone who has seen the bike says the (original) rings & cassette look fine. I agree. However, the chain is stretched well past spec. I'm inclined to do the chain rings when I do the chain and cassette, but am loathe to spend the $ if I don't need to. Thoughts? Thanks, Dan *Scary sidenote: I have this same attitude when in the bike shop. See how fast I just went from Nashbar house brand for $15 to a $50 Shimano? I don't allow myself to bring credit cards into bike shops anymore. |

If I get to spending $40 on this would I be notably better off spending the $50 on the M580?* The shiny ones look nicer but that's about it. Supposedly the chrome plated cassettes last longer, but that hasn't been my experience. I get the same mileage from a $15 house brand cassette that I do from an XT. Shimano cassettes do shift smoother, but even this is an aesthetic issue more than a functional one. Of course, the cassettes with aluminum spiders are lighter, if you care about that. If you don't care about appearance or weight, get the cheapest one that has the gearing you want. The chain: I'd like to spend under $20. Shimano or KMC? The place I'll be ordering from has both in stock. They don't have any SRAM chains, and I don't want to spend over $20 on a chain for this particular bike. Still, I hear great things about powerlinks & the SRAM chains. Am I really missing the boat if I don't go SRAM w/ the chain? I could buy one locally, but it'd be over 150% of my target price. Again, there's no reason to spend more than the minimum on this stuff. In my experience, the expensive ones don't last any longer. While some older KMC chains were terrible, lately I've had great luck with them. I just bought another 9 speed KMC chain from Nashbar for $8.45 (with free shipping too), the same kind I've been riding for the last 5k miles. These chains are usually $15-16, which is still cheaper than any 9 speed chain from SRAM or Shimano. A bike shop will rarely offer you anything for less than $30. You can almost always get 8 speed chains really cheap somewhere. It pays to stock up when they're on sale. A particularly good buy are the tandem chains from Nashbar, literally two chains for the price of one. Finally, the chainrings. This is a pawn-shop bike that until recently was on it's original grips (though worn out) and rims (not worn out). That's the best indicator to mileage I have. Everyone who has seen the bike says the (original) rings & cassette look fine. I agree. However, the chain is stretched well past spec. I'm inclined to do the chain rings when I do the chain and cassette, but am loathe to spend the $ if I don't need to. Thoughts? You can use chainrings until they're worn to nubs and start skipping, or until the chainsuck drives you nuts. These days it's usually cheaper to buy a whole new crank with fresh chainrings than just the chainrings. *Scary sidenote: I have this same attitude when in the bike shop. See how fast I just went from Nashbar house brand for $15 to a $50 Shimano? I don't allow myself to bring credit cards into bike shops anymore. Bike shops could work harder to bring better value to their customers. Matt O. I was thinking house brand cassette until I started reading up, there's a lot on the web about bad Nashbar 9 speed cassettes. Hearing you're using them without problem is encouraging. How pronounced is the smoother shifting of the Shimano? Is SRAM basically on par with Shimano? Thanks for the reply, it's certainly helpful. Dan |

Are you getting new shifters or using friction? Otherwise still with 8 spd, it's cheaper as well. SRAM PG-830 should cost around $20. I like SRAM chains, but KMC stuff is pretty nice these days, and cheap. Both my bikes run KMC chains. Shouldn't run more than a tenner for a 7/8spd chain. I very much doubt your chainrings are worn out. They last a very long time. $30 gets you on the road. |

This was with new chainrings and chain. I tried again with another one and had the same experience. Shimano cassettes do shift smoother, but even this is an aesthetic issue more than a functional one. The shifting was maybe a touch worse. Really not bad. The wear life sucked though. I switched to the SRAM 11-26 cassettes and have been much happier. $30 from aebike. -- Dane Buson - "The young always have the same problem how to rebel and conform at the same time.

Also that was a few years ago. Now I'm riding an 8sp mountain bike and a 9sp road bike, each with Shimano cassettes purchased for less than half price on eBay, and Nashbar/KMC chains. If you're leery of generic cassettes, the cheaper Shimano ones are still a lot less expensive than the Ultegra/XT, and just as good. Matt O. |

About the only problem I've found with Shimano cassette is I like the 9 speed12x27 combo. Its only available in DA or Ultegra. I am using a Miche 12x27 cassette on my Campy rear wheel. So far, it seems to work fine. However, it doesn't seem to shift as well as a Veloce 9 spd cassette. |
