Subject: Re: [CR] Rear Brakes Attached Forward of the Bridge

My view of side-pull brakes is dominated by what I mostly see. "Outside-of-the-forks" mounting of front and rear side pull calipers means that we mostly see calipers 'dressed on the left and right, respectively." How untidy for some who would never similarly unbalance tire labels or skewer handles, front and rear.

For which makes and models of on-topic side-pull calipers were the castings for front and rear arms mirror-imaged my the mfg so that with the conventional mounting, the cables would enter the caliper arm on the same side of the bike. More expensive to do that, of course.

And for that matter, a refresher or pointer to left vs right side location of the cable, stop, and adjuster nut for front side pulls would be welcome, too.
