12" Monkey Bars Slipping

AND make sure the bars are exactly where you want them prior to pinning.

Took the bike in this AM, mechanic said clamp was torqued down but bushings were loose...make sense? Hadn't heard of pinning until now but thanks for sharing the insight for future reference.

If the bushings were loose the whole assembly (bars, clamp, risers) was moving. The bars weren't turning inside the clamp.

a tip from an old favorite book, if the bars knurling is stripped or the clamp wallered out,

a piece of beer can as a shim is perfect, thin enough to fit,

soft enough to deform into the remaining knurling on the bars

thick enough to take up the slack if there seems to be no more adjustment on the clamp.

if you do the sew screw option first drill a 1/16 hole thru the clamp & say 1/6" into the bars then drill the size for the set screw. so the setscrew seats into the bars .

I didn't pin mine, and have had zero issues.

Sounds like a failure on whoever did the install to properly gap the top clamp, and torque correctly. If the clamp was tightened down all the way in the front, and then the back tightened, it would cause a severe uneven distribution of clamping force.

I'm not buying the bushings deal. Sounds like someone is covering their "oops".
