portable cassete cracker

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.

Pamir Hypercracker

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?

Campagnolo seatpost calibration tool. For models March to June 1979.

MagliaRosa - 02/04/13 - 8:06am

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

Campy fixed gear non drive side crank.

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?

timbo - 02/04/13 - 10:15am

Atganirider
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.

timbo - 02/04/13 - 10:21am

I found the other version:

Thats a Pamir Engineering Hypercracker!

atganirider - 02/04/13 - 11:49am

Timbo – much obliged, Sir!

Ripnshread - 02/04/13 - 11:59am

Carried one in my seat bag for years

lenny - 02/04/13 - 2:25pm

its a beer can opener

Oh that’s nutz! Just last week I was thinking of sending you a photo of my HyperCracker!

Now I just need to find it before I go to Nicaragua :-/

Clubber - 02/04/13 - 6:34pm

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.

endurobob - 02/04/13 - 11:24pm

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.

cleat wrench

Maxwell - 02/05/13 - 2:49am

J.A. Stein makes a similar tool now

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!

I have one of these that I found in my dad’s tool box. Cassette Tool

reteptterrab - 02/07/13 - 9:34pm

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.
