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.

Didn't 6,7 and 8 all have the same spacing? So that you could use a 8 spd shifter on a 6 speed? I would turn my daughter's 6 speed downtube shifter to friction and let her shift the 8 until I found some brifters.


7 & 8 are very similar. Six is not even close and spacing is
visually so different I can't believe anyone would even try it.
