    take it to a Bike Shop just to take out that 1 bolt they should do it while you wait? Or get some penatrating lube and let it sit a while then buy a stronger allen wrench.

    Hey... Me too. I think they squirt Glue on them to keep them from Backing out... Then some Chinese kid Whacks it with a hammer to freeze it to the shaft. I tried a torch to get things moving and that didn't do it either. (Always worked with Tractor Parts!?!?!?)

    do this. and not necessarily a stronger allen wrench, but one with a longer handle.
    longer handle = more torque, and it will be easier to loosen.

    Or just put something on the handle of it to make it longer. Saves you from having to buy or find a new one.

    I was in the same situation not long ago, one of the arms WAS NOT coming off without of fight. Some wd-40 works well as a penetrator and yes, putting some heat on things will help break them loose also. Allen = T-handle. Hammer = ancient chinese secret. Glue = ********. I guess you could jb-weld it to hold, but don't expect wd, a torch or the fat chick next door to break it loose.

    Look, I'm better than you, I just am.

    The more leverage you have the easier it will be to get the bolt out

    I had the same problem with a bike yesterday. I didn't care about the bolt because I was changing the spindle and it came with new bolts. What I did was take a hack saw and cut about 1/4 of the head off on 2 sides. That gave me a nice flat spot that I used a cresent wrench on. It came right out then.

    My response would have been something along the lines of: "Does your bike have computer controlled suspension? Then shut your piehole, this baby is from the future!"

    Hey Fuzzy, not trying to protect the guy, (not at all!) but I think he meant "Lock-Tite" glue that some manufacturers use to keep the bolt from coming loose, the torching method works but is usually used to remove a part you do not plan on using again, and the "Chinese kid" part is his attempt at making fun of sweatshop conditions in some other countries, he's just not bright enough to put it into words that will not offend anyone is all, or maybe your right and he's just a troll! LOL! ;0)
    You see, their morals, their code...it's a bad joke, dropped at the first sign of trouble. They're only as good as the world allows them to be. I'll show you. When the chips are down, these...These "civilized" people...they'll eat each other. See, I'm not a monster. I'm just ahead of the curve
