Shimming/lathing dropper post for odd sized tube.

This story seems a natural 'fit' for this thread.

A fellow rotorburner who shall remain nameless had an unfortunate incident in the skills park at Stromlo late last year and has hardly ridden since. As they 'there's always time for lube'...well there wasn't....result...

Displaced coccyx...from the inside:distrust:

Ended up shimming out the frame and running a 27.2 with a 30.0-27.2 shim. Mast on a dropper is too thin, but would reem a frame if couldn't shim it.

Were you ever brave enough to try that shaved post or did self preservation kick in?
 
On a similar tangent, has anyone used a shim on a dropper post?

Looking at a new frame that's got a 31.6mm seat tube (carbon) and my relatively new Fox dropper is 30.8mm. Obviously a new post is the ideal way to go but a new dropper is going to cost around $500 over a $20 shim

Yes. I've done this with a KS Lev and it works without any issues at all.

On 3 bikes currently. Works a treat. Get the USE branded ones. $10 at wiggle.
Might have a spare spare now. Can check if you need one.

Awesome, 10 bucks at wiggle is cheap enough but if you've got a 30.8 to 31.6 laying about I'll send you the money rather than overseas

Yep, running shims on both my bikes with 31.6mm seat tubes. No issues.

cheers for that, makes sense. So much to play with in the words you use though, reaming, shims, mast. if a bloke had a suspicious mind he would think it was a setup.:Banane20::Banane16:
