installing/removing SRAM Force 22 crankset ...is this normal?

Had a brand new SRAM Force 22 crankset installed on my bike in January. It replaced a Shimano Ultegra 6700 crankset, so this is my first time dealing with SRAM's paradigm for installing/removing cranks.
Since this is my S&S coupled travel bike, the cranks have to get removed any time I disassemble & pack the bike. So last night was the first time I've prepped the bike for travel since getting the new SRAM drivetrain.

All the youtube videos I consulted showed some happy smiling guy insert an 8mm hex wrench into the non-driveside crank, give it a gentle counter-clockwise nudge, then continue turning until the slef-extracting bolt comes off the spindle and everything pulls apart nicely.

I swear to freaking christ I had to wack that 8mm hex wrench with a cot-dayum sledgehammer to get the bolt to turn! Seriously.

Inspecting the self-extracting bolt and spindle end I could see no use of Loctite, just grease.

Was the guy who installed this out of his mind (and/or ignoring the recommended torque spec) or is there something about SRAM's design that typically makes removal this difficult? This really does not seem normal. Or practical.

IMHO that’s fairly normal. The torque spec for that bolt is pretty high — something like 55Nm. While I’ve never had any of mine seize, it usually takes some grunt to break it free, especially if you’re just bracing the crankarm with your other hand. I’ve installed and removed one of my GXP cranks so many times that I bought a spare fixing bolt because it seems like it’s only a matter of time before the 8mm hex flats on the existing bolt strip out just from fatigue.

Instead of a (I assume) hex L-wrench get yourself a good-fitting square drive 8mm driver and use a ratchet or bar for better leverage. Getting a 55Nm-torqued bolt unstuck is going to be tough with a 6 inch lever.

^^This. Plus, on Red at least, you remove the drive side so I have a length of 2x6 that I can place under the pedal to hold the crank in position. I use a long box wrench on a 3/8 drive ratchet to give me enough leverage, otherwise a BFH on the ratchet itself a couple whacks gets it loose. I haven't tried it, but I have a 12v impact driver for taking off lug nuts (works great for that) that would probably do the trick.
