Try your equivalent of RP-7, AKA Rat-[censored], WD-40, or anything else similar. One rider in days of yore had a seat post that wouldn't budge. He stuck it in a vice and managed to flatten it, but it stayed stuck. We referred to it as an aerodynamic seatpost (LOL) It was a KMart bike of course.

That's ISIS, right? Aren't the cranks self extracting? If that's the case then you'll need to keep the cover on.
/s
Yes, it's ISIS. How will I get them off if the cover is on? These were on the bike when I bought it. All my others have been x-type and they are easy.
Looks like I'll have to take the whole thing to the LBS. I was hoping to save some money by stripping it down myself. I've also got a problem with the rear disc brake. The hose was thread through the cable holders and then bled after. So I guess the only way is to cut the brake hose.

Scratch the self-extracting bit. I think for ISIS you need to buy a special bolt setup for that. Anyway, if you're not getting anywhere with the bolt and you're afraid of stripping it, i'd drill some little holes in the plastic and try to snap it out with some needlenose pliers. Not 100% sure that'll get you better access to the bolt's threads (which could probably use a shot of WD40/Liquid Wrench/whatever, but at least you'll have tried the option.
Words of warning: -- Be sure not to ding up any metal bits with the drill. -- I'm pretty impatient these days as repairs go, and I haven't mucked around much with my ISIS. There may be better solutions.

Did the plastic piece from the other side have any threads on it? If they don't, just unscrew the bolt.
I had some Specialized Strong Arm Cranks that had bolts like that, but the only thing the plastic piece did was keep dirt out. If you unscrew the bolt the plastic piece comes right out.

It's not self extracting. I use a 8mm hex bit in a 3/8" rachet handle. Apply slow even pressure in a CCW direction until it pops free. I usually lean over the bike and push down on the rachet handle for leverage. The plastic cap should come out with the bolt and then you can use a crank extractor to get it off the BB axle. I think those cranks are square taper. I'm surprised the carbon fibre stickers have stayed on this long.
ok, you need a 10mm hex wrench, period. DO NOT USE WD-40!!!! that [censored] is the absolute worst s*** on the market for bikes. WD-40 is made for displacing dirt and grease, like the grease in your BB that it will inevitably soak into when you spray your crankbolt. we use Tri-Flow at Down Cycles, it's teflon inpregnated and is not designed to displace grease. If after you soak that bolt in tri-flow, it still doesn't come out, find something to slide over your wrench to get some more torque. finally you can always try an impact drill with a 10mm bit. the bolts you have dont appear to be self-extracting from the look, most self-extracting cranks have some fanciness on the crank-bolt, yours are probably just standard ISIS sized crank-bolts. if you still have trouble getting it out, you can bring it to your LBS, but I can assure you we're going to do the same thing I just said, there are no special tools we use to get stubborn bolts out, just fat-power, lube and patience.
btw....this should be a good lesson to constantly check your crank bolts to make sure they are not seized and are tightened propery.

Thanks. I will try soaking it. I have tri-flow on hand. It's an older Race-Face Prodigy and I really like them. Just a good solid crankset.
I tried one of the hex wrenches I have and ended up stripping the wrench. I guess the next step is to hook up the compressor to the air hammer.

You do know that WD-40 was designed to displace water ... right?

If you are using aerosol Triflow it will dissolve grease just as fast as WD-40 since it uses a similar volatile solvent as a carrier.

Do you think it would be easier upside down and off the stand? How do I keep the crankarms from turning. while pushing down?
The PDF directions I downloaded didn't look like square taper. The stickers are still on because this bike gets little use in this area. The last time I used it was with Sorni and Chip in SD and that was a while ago.

How did you get the crank arm off on the other side? Was it a cap or a hex bolt with a collar? John
Hey John! The arm didn't come off, just the bolt. That was another problem. I need a rubber mallet (I've got tons of tools but not one of those). The cap is a metal hex bolt with a very important washer (according to race-face).

CF stickers imply square taper. Current Turbine cranks are ISIS... they probably don't have the old manuals anymore. -- Phil, Squid-in-Training

It's generally easier to really torque on stuff off the stand. I've done it with the frame upside down. I hold the crankarm in one hand and the wrench in the other. Either opposite each other (3 & 9 o'clock) or nearly together and pull/push them toward each other. The key for stuck bolts is slow even pressure until it breaks free. You can slip a pipe over the wrench handle for leverage but don't jam on it. Slow even pressure!!! Either the bolt will break free or break off. You can try to get penetrating oil into the threads. The nylon dust cap will pry off the bolt with a screwdriver (you'll have to mangle it a bit) to get the penetrant to bolt threads. Also use an new (sharp) hex bit. An old worn one will round off the inside of the bolt. You can sharpen an old one with a bench grinder but take care not to overheat the tool. It will soften the metal. Clean any mud or stuff from inside the bolt so the tool can bottom out well.
Also it really looks like a square taper crank version in the picture. You will be able to verify by looking in the hole after the bolt comes out. You'll need the appropriate crank arm puller to get the crank arm off the BB axle. A rubber mallet probably won't work.

If it is an ISIS and you try to use a square taper crank puller, it won't work, and you probably won't damage anything because the piston of the puller will go clear inside the entire BB spindle. If it's a square taper and you try to use an ISIS puller, it won't work, and you will likely destroy the crankset because it will be pushing against the extractor threads!

If a rubber mallet works, you're looking at buying some new cranks as well.
