Dumb question, but how do you remove the pegs?

  I have try my smallest wrench key (7) and it did not catch the screw, what tool are you suppose to use?

[redhenracing2]

mine just have a little pin going through that is held in by a circlip. using a hex wrench would do absolutely nothing for it, unless yours are different than mine

[gregvhen]

get a flat head and take the clip on the bottom off. watch out though, it may very easily shoot off and get lost.  then just slide the pin out.

ditto, pry out the circlip, but watch where it goes, or hold a hand underneath. I lost one of mine for a good 15 minutes of looking once.
