looking at the chain line and the one idler.have not seen a bacchetta in person and was wondering
about the idler .Does idler have one groove or two ? Does chain rub the chain as it runs over and
under the idler.

single idler, double groove, drive side runs under idler on inner groove, return side runs over
idler on outer groove. No chain-chain interference. Pretty standard.

Some early Bacchetta incarnations had the Idler too close to the inside. This would pull the chain
over the soft inner ridge. newest models have a bushing to space idler farther away from the freme.
Sometimes the chain will ride away from the idler guide bars and the outside (return) chain will
drop off the Idler. NBD.
