Rear Derailer

Rear Derailer
Will the Shimano XTR rear derailer work with an 8 speed cog?

I have a Schwinn hardtail bike, and I’m looking to upgrade after I ripped off my last derailer.

I might consider an XTR front derailer as well.
This is a MOUNTAIN BIKE
the derailer that is now broken was an Alivio, which worked decent, but the front Alivio is really slow and rough… even after fine adjustments

Hey,

Yeah man… You just need to set the limit screws. It is the shifters that determine the gear spacing. The derailler just does the work.

Also, keep in mind, derailler is only part of your shifting. If you pick up deore or better shifters, you’ll notice a nice improvement.

Here’s what to do.

1. screw in both limit screws (L,H), and both barrel adjusters (shifter and derailler). Remove the lower pulley from the derailler with an allan key, install derailler to frame, and install the lower pulley again with the chain on it. This way you don’t need to break the chain.
2. start pedalling, and slowly unscrew the H limit until the chain runs smooth on the smallest cog. Then pull the cable hand tight, and fasten it.
3. start shifting up. if it doesn’t go, unscrew a barrel adjuster until it does. When you get to the lower gears, keep shifting up, and slowly unscrew the L limit, until you are able to shift smoothly into the lowest gear.
4. shift back down, if it won’t go smooth, you either unscrewed a barrel adjuster too much, need to replace cable and housing, or your derailler hanger is bent – which may be a possibility if you wrecked your previous derailler.

There you go…

enjoy the new derailler
