While swapping handlebars a couple weeks ago, I discovered that my clutch perch was broken - the part that clamps to the handlebar is in two pieces.  There is just enough grab remaining to hold it up, although it will slip a little when riding into a stiff wind.  



Does this part slide onto the bar from the bar end?  If so I guess I will have to remove the hand grip to replace it, es correcto?

Correcto Mundo.

You want to replace or fix it - nothing worse than going to grab for clutch or brake and finding out it's not there (because it was loose and slipped down out of reach)!!

And be careful when tightening them back up (mine came loose - clutch) - it will strip out very easily!
