I am converting my bike from a shimano 9 speed to a 10 speed setup.

While trying to adjust my rear derailleur I am unable to shift onto my 32 ring and when I shift down to the 11 ring I am getting two clicks with out the chain moving any further. I am running a 11-32 cassette.

It shifts just fine into all the other gears. Does this conversion need a shim behind the new cassette and the cassette hub? If so, what do I need?

Thanks for your help.

IF you needed a shim, the cogs should rattle.

Typically, a 10 speed cassette will need a spacer so that the lock ring doesn't bottom out.

Are you using a RDER that doesn't handle a 32T cog?
It's helpful to specify what hub & RDER you have.

Many shifting problems like the one you describe "and when I shift down to the 11 ring I am getting two clicks with out the chain moving any further." can be cable friction/tension related. But when doing more then one change cause and result aspects get lost. Andy

Kind of sounds like your limits aren't properly set.

Are you using the 9-speed derailleur with the 10-speed cassette?

I am running Shimano 105 5700 10 speed. Shifters are 10 speed, the derailleur is a 5701gs 10 speed, 10 speed chain.

The limit adjuster screws have been adjusted but it wont go to to the largest cog as it stops at the cog next to it, and the lower limit I had to screw quite a way in it seemed to me to let me up with the small cog. It seems like it just needs to have the cassette moved out to line up.

I am using the Rolf Vector rear wheel I had with the 9 speed cassette. I pulled the 9speed cassette off and replaced it with the 10 speed cassette. It acts like to me that it needs to be shimmed outward.

Can you grab a section of the rear gear cable and pull it with your hand to see if the der will then move under the largest cog? If you can and if the der does move then the limit screws are not likely the problem. But the cable tension likely is.

Cable tension issues might be so common a thing as just needing tightening via the barrel adjuster or repositioning the cable under the anchor bolt. But there's also the chance that the casing reinforcement strands are punching through the casing end caps, or the cable end isn't any longer seated in it's fitting in the shift lever, or the cable is fraying and about to break just inside the lever.

If you can grab the cable but even still the der won't move over to the largest cog then the first thing to look at would be the limit screws. But the OP description suggests cable tension is a big part of what's going on. Sometimes there is more then problem happening at the same time too. Andy.

Screwing in the L screw prevents going to the larger cogs. What do you expect to happen when you screw it "quite a way in"?

Yes, a 1mm spacer is needed for 10-speed cassettes. Shimano Cassette Cog Spacers > Components > Drivetrain > Cassette Spacers & Lockrings | Jenson USA

I had this problem when I was setting up my 9-speed. For me it was a cable tension issue. Like @Andrew R Stewar says, you can manually pull on the cable to make it go into the largest cog, which I could, then I knew it was the cable tension. Also, a 1 mm spacer would cause a chain to not shift.

Step 1 - Disconnect the cable. Shift the rear derailleur by hand, and verify it can reach all the cogs. Adjust limit screws as needed to reach 1-10. This gets any cable problems out of the way.

Step 2 - Hold the loose end of the cable in your left hand and pull on it a bit, while shifting 1 through 10, up and down. Does it easily go through all the gears ? Any roughness or sticking ?

Step 3 - Once Steps 1 & 2 are set, Attach the cable and follow basic setup instructions.

What cassette are you using? A shimano one should come with a spacer. A SRAM one doesn't need one.

Finally. And that shim is 1 mm thick. If you don't have it, and you need it, you should be able to get one at a bike shop.

I am using a Shimano cassette but it did not come with a spacer. I will check with the local bike shops tomorrow. Hopefully that is what it is.

Will let you know what happens if I get one and if that solves.it.

Thank you.

That's what it is. All 10 speed Shimano cassettes should come with a spacer. The table at the bottom of this article nicely gives the situation.

...but wait! There's a caveat. I just realized a shimano 10 speed 11-32 cassette is likely a mountain, and not road cassette. I don't believe that mountain cassettes come with or need the 1mm spacer. Oh what a complex web Shimano has woven!

You are correct. I picked up a spacer today and tried to install it this evening. It did not fit, I was unable to install the last cog.

Realizing that a shim can't be the issue, I disconnected the shift cable and redid the entire setup procedure for the rear derailleur as was suggested . That must have been the issue as I was finally able to get it shifting correctly and through the whole range of gears.

Thank you everyone helping me with this, I am building up frameset and am learning something new as I greatly appreciate it.

It is inconceivable to them that anybody would want to mix road and MTB components.
