Shimano 6sp
Is there more than one type of Shimano 6sp or is it all
intercompatible? I've heard that this was a standard class of cheap Shimano groupsets and therefore that chains, chainrings, clusters etc from one Shimano 6sp bike ought to work on any other one. I want to take some bits off one old clunker MTB to fix another clunker MTB and would like some assurance that this will work, that I'm not going to find myself half way to uni with a broken chain or toothless chainring or something because I'm using incompatible bits. I took the bike for a round the block test ride and it seemed ok, though a little noisy. I suspect I need to adjust the gears to deal with the noise, but I want to be sure because if it breaks I get stranded 20km from home... Travis |

Travis There are different widths in the chains. ie You can't use a standard chain on a 9 speed cluster too wide to fit between the gears. |

Sure, but donor and receiver are both 6sp, so I should be ok? IMO, the cluster and the chainwheel should be okay. The chain is the more likely to give problem if it is from a third source rather than worn into the chainwheel/cluster combination. Have a good look at the cluster cogs for wear signs. also flip the bike and closely watch chain/cog matching. If you see air, thenyou might have problems under power. All you cn really do is give it a go. |

What do you mean by "a little noisy"? Noisy on the shifts, or noisy
all the time? Another point to bear in mind is that chains stretch, and sprockets wear. A stretched chain might work quite well on its worn sprocket mate, but not on another sprocket that is worn to a different degree. The older the bike the more likely this is. -- Phil |

I managed to scrounge up a much better bike which I'll be riding from now on. All of this was triggered by a 2 week old wheel on my crappy commuter MTB breaking some (5!) spokes. I took it back to the LBS, who said clearly it wasn't strong enough for the combined weight of me, my bike and my panniers, and I'd need a stronger wheel which unfortunately they couldn't supply because they weren't available with compatible hubs or something. Rather than swapping it for another wheel that will break just as quickly he gave me a refund. Not wanting to be without a commuter bike for a while I took the rear wheel off another old MTB I've had in the shed and fit that on. Although I have a reasonably full set of bike tools, I didn't have an appropriate tool for removing the cluster so I left the old one on (which in truth looked less worn anyway). It seems to work ok but was a bit rough and noisy. My biggest fear was that somehow something might break and I be stuck half way to or from uni. Anyway, turns out my brother has a rather nice hybrid which he wasn't using and I've taken that and fitted my panniers and stuff to it. This will do me for a while. Travis |

Sheldon Brown has these things well documented at: http://sheldonbrown.com/freewheels.html He says that there are two standards for 6-speed sprocket spacing, 5 mm and 5.5 mm. And two different chain widths to match. John |
