    How do I remove Hollogram SL crank bolts?

    I want to swap out my crank bolts and i,m having trouble.

    I have a loing 20cm, 10mm hex tool for the crank bolts.

    But I cant get the suckers off. They are extermely tight and I dont want to put so much pressure on the frame as to flex it.

    Am I doing something wrong? I can put the hex all the way in or should I just be putting it in to the depth of the bolt?

    My LBS do everything up to so tight.

    35 Nm if i remember is the force

    + dirty + time ...

    so you need to have a long arm for the 10mm hex allen key

    you need a long torque wrench

    I cant find torque wrenches longer than two feet.

    When I see the frame flex under pressure I get worried. Thats some force ok.

    i think a two foot wrench would be a bit over kill, it's not a JCB you're working on!

    support the frame by holding the crank arm firmly while you apply the pressure.

    lefty loosey - righty tighty!

    A 20cm long 10mm hex should be long enough, if you can't, try this:

    Insert the hex in the bolt more or less parallel to the crankarm with the crankset aligned driveside toward the rear, horizontal. Get on the bike, put your left foot in the pedal, stand up and instead of clipping your other foot in the other pedal, put it on the hex (maybe just the heel) and apply some force to both feet with your weight, like if you pumped the bike... Should work and should only apply torque in the same direction you put when pedaling, no side loads. For the other side, same thing except that the wrench will be pointing forward and your right side pedal toward the rear... You can do this next to a wall so you can lean on it for support.

    Related free tip of the day: this works great for stuck pedals, just remember the thread direction though.

    thanks for the tip

    i still have a scar on my hand from not having the chain on the big ring when i had to use a cheater bar to get a stuck pedal off. so when it finally broke free it was like jamming my hand in a circular saw.

    it's something you only do once.

    I had stuck pedal a couple of weeks ago. They had only been on the bike for four weeks. The shop said they may have to cut it off and drill it out.

    In the end they managed to get it out.
