Cable-from- | [[Datei:Cable-from-under.JPG|right|Zugführung von unten]]On a step-through (lady's) frame, mixte frame or monotube frame, a cable may be fed along the uppermost tube(s), then upward to a brake at the seatstays. This is the traditional routing on English three-speeds with lady's frames. It minimizes curves in the cable, and so it minimizes friction. | ||
Older sidepull brakes conveniently allow you to switch the positions of the the anchor bolt and adjusting barrel. Many newer brakes have the adjusting barrel threaded directly into the upper brake arm. With these brakes, a bolt-on cable stop can still be installed to replace the anchor bolt at the lower brake arm. As shown, the cable is threaded through the adjusting barrel at the upper brake arm, then secured with a second anchor bolt. This installation is inelegant but it works. Perhaps someday, someone will offer an anchor bolt assembly that threads into the upper brake arm...The installation shown, on a Raleigh Twenty bicycle, also uses a home-made drop bolt. | Older sidepull brakes conveniently allow you to switch the positions of the the anchor bolt and adjusting barrel.

Routing the cable from underneath to the cable stop at the top of the head tube may be desirable on a front centerpull or cantilever brake on a folding bicycle so that there is enough cable to allow the handlebar and stem to be lifted off and laid alongside the frame. The cable housing is attached to the yoke. In this case, inverted cable attachment to drop-bar brake levers also can be under chainstayuseful (see John Allen's installation on his Raleigh Twenty). Routng the cable from underneath is also necessary on a Freestyle acrobatic bicycle with a rotor (which allows the front wheel/handlebar assembly to turn around and around without fouling the cable.). | Routing the cable from underneath to the cable stop at the top of the head tube may be desirable on a front centerpull or cantilever brake on a folding bicycle so that there is enough cable to allow the handlebar and stem to be lifted off and laid alongside the frame.
