Freewheel/Casette Spanner/Wrench Confusion, Help!
#1
Hi, I'm new here and fairly new to bike mechanics. I have an old Mongoose Rockadile SX from 2004. I'm trying to remove the 7 speed shimano casette it came from the factory with to a new wheel. I made sure I got the spacer as the new wheel has an 8-9 speex hub. I have a cheap x-tool bike tool kit. It has 2 free wheel wrenches/spanners. Both are too big. One is only slightly too big. Maybe 1mm if that. I think that spanner/wrench is an fr-1 but I'm unsure. Can anyone help with advice or links to the right type of casette spanner/wrench?

The wheel I have bought is a Halo Combat II, perhaps I could just get another 7 speed casette. However after this experience I'm tentative buying one just in case it doesn't fit the wheel or the tools I have. Any help or advice would be appreciated greatly. Looking forward to your responses.

If you need more info/pictures let me know, I'm pretty green to all this so be gentle.

you may want to post pics of what you are working with, If you are correct of the year. Those are now entry level compared to the mid 90's rockadile sx's which were in the five to 6 hundred dollar range.
Had normal cassettes and not freewheels.

You have freewheel removal tools. You need a cassette tool & a chain whip.
I have an Ice Toolz like the FR-5G, ended up knocking the pin out.
This is how you do it.

According to Bikepedia, your bike came with a 14-28 7 speed cog set. For a 2004 model bike, that would be a freewheel, not a cassette. 7 speed cassettes mostly disappeared from new bikes in the mid 1990s. If the smallest cog is 11 or 12 teeth, USUALLY it is a cassette. If the smallest cog is 13 or 14 teeth, USUALLY it is a freewheel. There are exceptions.

That all said; I would suggest a new cassette and chain; as the freewheel will never fit on your new wheel. I like SRAM and Sunrace cassettes and KMC and SRAM chains.

That's exactly the kind of advice I was looking for. Thanks. Is a new chain essential?

Hi, as I'm in the UK I've looked for similar products on the Amazon.co.uk eligible for fast delivery tomorrow, if I order within the next 8 or so hours I am guaranteed delivery tomorrow. (I'm a bit impatient after being off the road 2 weeks)

http://www.amazon.co.uk/gp/product/B004XVORBU/
http://www.amazon.co.uk/gp/product/B002G340LE/

Would these be suitable to apply to this wheel (with the correct spacer):

Using the tools found in this kit:

or at worst, if my tools aren't suitable, visit my local bike shop when I'm not working on Saturday and ask him nicely in exchange for some money, if he would fit the new cassette to my new wheel.

Thank you so much for everyone's help so far, I didn't realise you'd all be so efficient at responding. What a lovely community.

you have the tools to install or remove a Shimano compatible cassette (SRAM,sunrace,dnp).

new chain is required.

Thanks so much for you advice Nigel you've been very helpful. I have just ordered those parts, they are guaranteed to arrive by 4pm tomorrow. It looks as if, thanks to your help, I will be riding again by the weekend. I can't thank you enough. Positive vibes will be heading your way this weekend.
