Why does my shifter feel stiff?

Why does my shifter feel stiff?

Stiff shift can be synchronizer, linkage, contaminated gear oil or misaligned shift linkage.

Can a grip shifter be too hard to shift?

There is one screw that if I loosen it, the cable becomes free and yes I can pull it a bit to make the tension tighter, or looser when I screw it back on. Also, when I pull on the cable from the middle parts of the cable, the derailleur does move to shift gears if the cable is tense, just not from the shifter, the shifter barely spins.

Is the shift lever stiff and difficult to move?

You can move through all the gears and some times it is fine and other times it is stiff. But almost always 2 and L are stiff. I don’t think it is the shift cable.

What makes a shift cable hard to move?

Thank Robert. When a shifter becomes hard to move, it is usually the interlock cable. AKA, shift cable. This cable slides in a housing and connects directly to the transmission. When this cables becomes worn, it gets hard to move inside the housing.

What kind of bike is too hard to shift?

The bike is a Diamondback Cobra Jr. 20″ mountain bike. It has a single right hand six speed twist/grip type shifter that is too hard to shift. It requires substantial force to move from 6 to 1, especially from 3 to 1. Moving from 1 to 6 is not as difficult, but far too difficult for any child, and tiring (hurting) for an adult after a short while.
