Cassette Removal Tools

Unless they have altered it since I bought mine, it has two "options" on each side so covers smallest cog sizes of 11, 12, 13 & 14... unfortunately Xenophon2 this doesn't help you for your SRAM cassette  but hopefully clarifies in case someone was wondering

The Decathlon tool appears to only work on cassettes with a smallest cog of 11 or 14, though.  No dice for my 10-42 SRAM cassette.  I use a conventional Park Tool chain whip along with their 'pro' (I guess that translates to 'you'll have to use it 20 times/day in order to justify the cost') removal tool.

Where can you get that btwin tool from though?
All my searches come back to decathlon which says not available online.

The Decathlon chain whip is right at the top of my 'why didn't anyone else think of that?' list, it's simple, cheap and straightforward to use, in a word 'genius'.

+1 for the Decathlon tool.  Superb bit of kit.

The Decathlon chain tool is a work of genius.

These are supposed to be good and give usual Decathlon value for money:

Not sure, but I would guess that these will make it harder to turn but less likely to slip. I find it always takes 2-3 attempts to get a chain whip seated right (although I think that’s because I only use it at most once a year).

That's nice, I like my normal Park chain whip but if I needed to replace it I'd get a Pedros Vice whip.
