I’ve wanted to do this for a long time, but assumed I’d have to fabricate a special mount for the bar-end shifter. I was thinking I’d mount an inch of handlebar side-on to the tube (big hole on one side for the allen key, small hole across for the bolt).
The whole story is here on Pants Pants’ photo (he
doesn’t didn’t used to allow bloggeration of his pictures). A closeup picture of the seatstay mounted shifter.
His bike is the impetus for me to finally buy the S3X hub I’ve been talking about for years!
