i plan to change my 2 rings to a 3 up front. this is an old 10 speed and the fd has a built in cable stop and the derail cables make their turn above the bottom bracket. a short length of cable housing runs from the turn at the bb to the fd cable stop. there are no triple fd with a built in cable stop so i need to add one. the seat tube is 1 1/8, i am looking for a stop.
1 using a cable stop hanger from a front brake steering stem 1 1/8.
2 a seat post clamp with a rear brake cable hanger for 1 1/8.
3 i can make a stop using a cut down rifle/pistol cartridge case, using the primer hole as a stop, a saddle to match the tube and case radius and a hose clamp.
4 any ideas?
