Hi there

it is a Shimano cassette removal tool which uses one of the chainstays as a counter force. I bought one of these ca. 1995 and took it travelling all over the world.

Regards

Andreas

It’s a “Hypercracker” from Pamir Engineering.

I have one of these buried in my toolbox. Did these only work with Uniglide or did these also work with Hyperglide cassettes?

@Jack – isn’t it the 1975 model? There’s a famous scene in “La Course en Tête” where you see Merckx using one.

Timbo – I still use mine for Shimano 8, 9 & 10 sepped cassettes. Brilliant pice of kit. Anyone have the other version with a length of chain on it for those cassettes with one or two screwed sprockets, then splined?

Now that my brain woke up, I remember that I have both versions. The other version has the curl that wraps around the chainstay and the attached whip captures the outer cog. I just haven’t had my hands on it for so long. Again, I think this was necessary for the Uniglide, but not the Hyperglide.

As above, it’s a Pamir hypercracker. One of those saved me on a 2day Orienteering event when my chain got wedged behind the cassette and couldn’t be removed any other way.

I would pay to see someone attempt to use one of those on a cervelo R series bike. I can’t imagine those spindly stays would stand up to that pressure.

Tool is awesome for touring however.

Anyone who answered a Pamir Engineering HyperCracker is correct.
From Anton: This is a PAMIR ENGINEERING Hyper-Cracker

its a very useful tool for touring and the like. line it up with the frame to remove your cassette with the chain acting as the chainwhip

it also has 14/15 spoke nipple tools too!

Thanks for posting this! I bought mine in the mid 1990s and still have it. Dug it out of the toolbox today so I didn’t have to bring a chainwhip home from the shop to switch out a cassette. Thing works awesome.
