A cassette recommendation?
As can clearly be seen in this photo:
http://picasaweb.google.com/j.michae...59497885260002 there's no way that the Shimano "Mega Range" freewheel that I bought online will fit onto Mrs Squirrel's rear hub. I done ordered the wrong part. Some of you guys always seem to have the inside track on the good online deals. Who's got an 8-speed cassette with a honking great 34-tooth bail-out cog? -- Mike "Rocket J Squirrel" Bend, Oregon |

Who's got an 8-speed cassette with a honking great 34-tooth bail-out cog? One of the reasons I went 9sp is for the 34. But SRAM do a 11-32 (actually more than one - 3 different models) which has got to be close enough? cheers, clive |

Shimano HG40 cassette It's also a MEGARANGE! Woohoo! I got me one. Cheap and does the job well. The one that doesn't work (see the picture in my OP) is an HG40. It's a 7-speed and doesn't fit the hub. Dollars to bagels I blindly ordered the first megarange I came across online and should have ordered an 8-speed cassette version and not a 7-speed freewheel version. That's me, being hasty again. Maybe more happiness would result from this one instead? http://www.modernbike.com/itemgroup....175588&TID=367 That's the one. That there cassette's one of the great reasons to run 8spd. $18 clams a pop! Shifts fine, lasts a good long while. |

[Megarange] Why then, that's the one I'll get! Many thanks! Wait a second! If you were running a "normal" cassette before, you might not be able to install a "Megarange" one. Your rear derailleur might not fit. The point is, with "normal" derailleurs the upper pulley follows an arc which should match the arc defined by connecting the circumference of the cogs. In some cases it will hit the "megarange" cog when set up right for all other gears. When you set it up for the "megarange" thing you might get poor shifting performance on some of the other gears. Check out something else: You have three (?) gears in front and eight in the back. Count the teeth on all cogs and use the gear calculator on Sheldon Brown's website to compare a Megarange setup with a "normal" 11-32 cassette. Mark the gears that are not close doubles of the other gears and count the number of "useful" gears you have left. In my oppinion, the Megarange casette does not have a good distribution of gears: the small cogs are spaced rather closely and the last one is a huge step. A more evenly spaced 11-32 cassette gives you better spacing of the gears and the "mountain" gear is still 32 teeth (instead of 34) which is quite close. Of course, the "Megarange" thingy is flashy, but the practical value? I'd rather exchange the 32 teeth cog for a 34 teeth one and leave the rest ;-) Or sacrifice the 11 teeth cog and add a 34 teeth one at the other end ;-) Have fun anyway... |

The redundancy in ratios is not much of an issue in this case as Mrs Squirrel tends to use her middle ring 90% of the time, and then downshifts madly when she gets to hills. The 7 closely-spaced cogs will give her nice ranges for for the mild grades hereabouts, and the large cog + her inner ring will give her the bailout gearing she needs when the few steeper hills are encountered. I think her bottom cog right now is a 28 toother. As for the derailler, I'm putting on a Alivio which should take up the extra chain and clear the big cog. If it shifts poorly because it doesn't follow the profile of the cluster, then I'll try something else. This arrangement is surely just a step in the path, not necessarily the optimal solution. My posting history shows clearly that I slug through these things step by step. Besides, even if it shifts poorly, one can take comfort in the fact that this is a Megarange cassette. Mega. Range. It has the word "Mega" in it. It is therefore the most epicest cassette ever. -- Mike "Rocket J Squirrel" Bend, Oregon |
