I recently had my rear derailleur replaced along with new shifters on a 18 speed mountain bike.

Shifting in the lower gears is smooth and there is no noise when pedaling.

I can shift smoothly into all gears however, there is a "clicking" sound when I am in the upper gears.

The bike tech who did the work said he could not find a seven speed shifter and installed an eight speed shifter and told me he would make adjustments so it would work.

I have been told this.

"It is a problem, but can be fixed by also replacing the freewheel, but I definitely wouldn't be paying for any service from a tech who didn't know this would be a problem."

The 8 shifter is compatible.
Common problems include cable/casing/ferrule issues and rear
changer misalignment.
It ought to shift well and quietly with all new equipment.
This has a new seven chain, new FW and new cable/casing right?


Since when is an 8-speed shifter compatible with a 6-speed cassette or freewheel?

Cheers


Yikes. You're right. I missed that.

If it's still a SIX freewheel, there's no way that shifter
could work.

And by the way, WTF? Six shifters are cheap and plentiful.
As are Sevens.


Is this what I need?

I think I can sucessfully install it.

I found this video on adjusting the derailleur.

p.s. If your local guy sold you an 8 shifter for a 6 system,
and then charged you to install it and make it not work,
ride over there at your earliest convenience and straighten
him out. That process would range from politely pointing at
the number "8" on the shifter while loudly counting
sprockets, "1, 2, 3, 4, 5, SIX!" up to and including not so
politely wrapping your bicycle around his face.
