Grip Shifters
#1
Currently renovating a child's bike. It has 24 inch wheels and is a suitable size for a 7-10 year old. Anyway it has grip shifters. it is a six speed with three chain rings on the front derailleur. On the rear derailleur the shifter does not appear to move the gear cable at all when shifting from 6 to 5 and 5 to 4. I am actually holding the cable with my finger and thumb against the cable casing when testing the shift. No movement. Can not feel any resistance on the grip either when doing this. I am assuming it is just worn out and needs replacing. Any thoughts?

when you twist it tio 4to 3 does it then move the cable?

if so, it most likely slipped in the derailleur cable clap... reset the twist grip to 6 while pulling the cable, then loosen the nut clamping the cable to the derailleur... Pull The Cable end until the excess cable is hanging out of the clamp... re-tighten the clamp nut.
you might need to use the adjuster on the derailleur to fine tune the shifting.

report back if it works, or not. and good luck. Cool
