I've got a 7spd bike (Kent NEXT Avalon) with a Shimano 14-28T rear
freewheel and 38T chainring. What I'm wanting to do is replace the rear gears with an 11-34T Sunrace cassette to give me more speed and a lower 1st gear for steep hills. My question is will the cassette fit? I assume I'll need a chain whip and lock ring tool. Anything else I should be aware of? Secondly, I'd also thought about replacing the single chainring with a 28-38-48T crank to give me maximum choices of gears. Any special tools required to do that? Other suggestions welcome. |

I would suggest that you check out this link which will explain very clearly the difference between a 'freewheel' and a 'cassette'. Hope this helps you. http://www.sheldonbrown.com/free-k7.html Lewis ***** |

I have a feeling that that bike has a thread on freewheel. You'll want a freewheel tool and a big crescent wrench to remove it. A Shimano Megarange freewheel in 11-34 should run 15-20 USD. With a 38T chainring up front, it'll handle anything short of alpine conditions. I wouldn't bother with a triple conversion, as you'll end up throwing more at teh bike than it cost in the first place. |

Be prepared to spend a few bucks on a new derailleur, and of course a new chain. That will require a chain tool, if you don't yet have one. - Frank Krygowski |

Most of those things work great with Meganerd cogs. |

Now I'm procrastinating about just buying a new 21spd bike of the same style. I'll make up my mind by spring.:-) |

And then I'd have to remove the wheel, etc., etc. Just decided I didn't want to spend my time on it so ordered the Sierra Madre model for $200 shipped. 28-38-48T chain rings and 14 or 13-34T freewheel. With a 21-89 gear inch, that should suffice. Original bike was only a 35-70 gear inch spread. |

My current one cost about 1.000 Euro and compared to the quality I've got, it's a real bargain (similar quality bikes come at two or three times the price). Here I could by a bike for 200 Euro, but I wouldn't ride it for a single mile - the cheap ones are really that bad. The brakes don't meet the rims, the gear shift is hard or impossible to set up right, the wheels are anything but true, sometimes the frames are not even straight. Not that I want to make your new bike sound bad - but I can't help wondering. Somebody linked you to Sheldon Brown's website earlier - please read the parts on brake setup and check your new bike when it arrives, it really only takes a few minutes ;-) Gotta go and get a new brake cable for my mate's bike ;-) Happy New Year. |
