I can say from experience this does not work well at all. Although as mentioned above the chain does run through the shifting is dreadful. I tried it with a 10 speed shifter but gears would always have a spot where they would jump. Just get a 10 speed rear derailleur. You will be glad you did.

Will it work? Probably. The range of movement of the mech wont be an issue and the chain will run through it, so I cant see why it wouldnt work.

Yes, all Shimano 8-speed shifters and rear derailleurs except Dura-Ace are compatible. Road and off road front derailleurs have different cable pull, but since both 600 and Claris are road component series, they are compatible too.

Once possibility is a rusty cable/housing. When the cable or cable housing gets rusty it can be the case that the spring of the derailleur can't provide enough force to overcome the friction of the cable moving through the housing. You can test this by disconnecting the cable from the derailleur and seeing if it is difficult it is to pull the cable ...

It is not uncommon for new bike or older bikes with new cable to require a retune after a few rides. The cause is cable stretch. With use the cable stretches slightly. If you purchased your bike from a local shop it likely included a free adjustment and fastener check after 30 days of use. You can also search for tutorials on line dealing with derailleur ...

Using pliers and turning the barrel adjuster counter-clockwise worked. Thanks for all the answers!

You can install an inline cable adjuster. There are several companies that make them.

Can I use a 9 speed shifter with a 7 speed drivetrain, with good shifting and without needing complex adaptations? Kinda, maybe, sort of... its complicated You could use a Shimano 7 speed derailleur with a 9 speed shifter, if you also used a wheel with a 9 speed cog. The 7 and 9 speed Shimano derailleurs use the same derailleur ratio of 1.7 (amount ...

It won't work. On a 7-speed cassette, the cogs are 5.0 mm apart (center-to-center). On 9-speed, it's 4.34 mm. This means that if you adjust the derailleur so it's in the correct position on the 1st cog, then by the time it gets to the 7th cog, it'll be 4.62 mm off from where it needs to be.

You can try it, but don't expect perfection. The width of a 7-speed chain is greater than the width of a 9-speed chain, therefore the component sizes, and the distance you need to shift, are different, even if only slightly. Whether this is enough to spoil your ride, only you can judge. A shop or a manufacturer might be somewhat more definite in their ...

Do you just need a brake lever? Then don't fit a shifting cable and you're sorted. The brake action and the gear change are different mechanisms inside. You could even remove the gear changing gubbins for weight. How do you change gear? Is the bike now a fixed speed by accident? Refurbishing a brifter's shifting mech is not hard.


2

You can use the brake lever without the shift portion just by disconnecting the shift cable. Then, you can attach a bar end shifter or a downtube shifter or similar to shift instead. You won't be able to replace just the shifter portion of the brifter (without probably canabalizing another brifter anyway and actually manage to put the old one together). ...
