Ergon Bar Ends

OK, just let me state right up front that I'm an old fart, and this probably is painfully obvious to everyone else, but these things have had me befuddled for some time.

The Ergon bar end/grip combo GC3 (now replaced by the GP5) has an aluminum ring on the inside with 2 different diameters.  The inner ring (larger diameter) fits over the grip handle, and with the plastic sleeve, it feels like you've pushed it on the handle bar all the way.  Don't be fooled like me.  No matter how tight I wrenched it down, the bar ends were still loose (one time the whole grip came off in Jeff's hand while descending!).

It's the damn outer ring that clamps to the bar, but the diameter is significantly smaller than the standard XC bar, so you need to pound a screwdriver into the expansion slot to get the ring to open up enough to slide over the bar.

When installed correctly, the expansion slot, is...well...really expanded.

Damn I'm old!
