Shimano 333 shifter problem
I'm having some problems with an old Shimano 333 shifter. The hub does shift gears, but the shifter (or maybe the hub) does not hold in gear. For those that know about these things, what do I need to look for to find out why it isn't holding. The shifter is a lever type on the handlebar. I'll supply photos or anything else that is needed, if necessary.
