    Shimano 7 speed Megarange 14-34 cassette

    Does anyone know the size of each gear for this 7 speed 14-34 cassette? Thanks.

    Nope, went through fairly exhaustive search on the net but found nothing, even the sheldon brown site, which list a lot of cassettes only has a mention of this 14-34T but does not have any more details

    The Sheldon Brown/Harris Cyclery site lists the size of each gear: 11 13 15 18 22 26 34.

    Are you sure you're dealing with a cassette vs freewheel?

    ummm...How can a 14-34 FW have 11 and 13 tooth cogs?

    The trouble with common sense is it is no longer common

    From The Shimano Website:

    MF-TZ37

    Gearing : 14-16-18-20-22-24-34T

    This is a freewheel but I would gess if there is a cassette version it would be the same.

    Why not? What are we talking about here? The OP says cassette. There exists an 11x34 cassette. There also exists an 11x34 freewheel (11 - 13 - 15 - 18 - 21 - 24 - 34) on that same Harris Cyclery website; both are Shimano. There are also other sized 7 speed freewheels listed (13x34, 14x34). There is also a 13x34 7 speed cassette. All the gear sizes are listed. There is no 14x34 cassette listed.

    remember that last jump to the 34 'bail out' gear is a doosy!

    what's your gearing up front?

    24-34 jump? That's huge. I've never ridden a bike with the megarange 34 cog. How hard is it to shift the 24-34?

    Thanks Shayne. Please coould you give me the particular url of the shimano site where you found the answer?

    Well I guess it is a free wheel, I thought they were the same thing. I am not aware of the distint difference between free wheel and cassette before, thanks for the eduction. But it is still a 14-34T.

    I have been using 32-18 for the last 2 days just to try out how it would feel like if I convert my bike into a single speed.

    So far I have been able to ride up a hill using 32-18 that I had previously thought would be impossible as I was using 22-24. It took a lot of hard pedalling but it was satisfying when I reached the top... I guess it would be slightly easier when I actually remove the derailleurs, 7 speed cassette and extra gears.

    Not hard to shift.......

    .......it's the fact that when you do shift from the 24 to 34 it feels like you've dropped a RING size and a couple cogs. If you're dying on a hill and switch into you're pretty much guarenteed to have to get off and walk for the sudden spin/lack of resistance increase. I still use one on my Rockhopper rigid that I use for road and going into that meg 34 is really a funky feeling.

    yeah, I picked up the good tip of using the shimano-europe site here at mtbr... to find info & download parts diagrams that aren't on the US site.

    New Shimano 7-Speed 14-34 Megarange Freewheel Cogs:14,16,18,20,22,24, 34

    I got the following from an eBay listing. New Shimano 7-Speed 14-34 Megarange Freewheel Cogs:14,16,18,20,22,24, 34. Having ridden a bike with this gear set I would say that it is accurate. I am a senior and not in great shape so I found it good in combination with 48-38-28 front cogs. For someone in better shape a 11 or 12-28 would probably be a better setup.
