Installing new wheels

markhewitt1978

Can you explain the process for a complete idiot (me!) in terms of what needs to be done and what tools are required.

Lets say I get an RS80 wheelset - which is 10 speed which matches the 105 10 speed setup a have now.

So I get the wheels, and a new Ultegra 12-30 cassette (same ratio as my existing one).

I put the cassette onto the hub and tighten it up, somehow?
Move the tyres and tubes - that's the easy bit!
What else? Would I need to adjust my rear derailleur somehow?

Wheels won't come with a cassette (the rear set of gear sprockets).
The cassettes will hopefully come with appropriate spacers, check what you need.
The sprockets slide onto the wheels freehub, and then are tightened on with a lockring (which will come with the sprockets)
You will need a cassette lockring tool to tighten the cassette in place, and a chain whip of the appropriate speed to hold the cassette in place while you tighten the lockring.

You then have a constructed rear wheel.

Further consideration, what is your current largest rear cassette sprocket? If you go to 30 as the largest, from 25 at largest, you will need to consider a chain which is 1 set of links longer.
You also need to check whether your dérailleur can handle larger sprockets, some will struggle over 28 or so teeth. This is to do with clearance of the jockey wheels (plastic wheels on dérailleur)

If you're putting a new cassette on your new wheel, all you need is a shimano splined cassette lock-ring tool and a big spanner to turn it. (I use a large adjustable spanner but other types would do) If instead you want to transfer your existing cassette you'd also need a chain whip to hold the cassette still while you're undoing the lock-ring.

You may or may not have to re-index your gears.

You won't need a chain whip unless you plan on removing the cassette again.

Your cassette should come with a 1mm spacer, put this on the freehub body first, then the rest of the cassette. It'll be in pieces, so have a look which order they all go on in before you start (it might be wise to place the cassette upside down then work down the pile transferring to the free hub body) The bits only line up with the splines of the freehub body one way, so look for the smallest spline and line up that way.

Use a lock ring tool to tighten down the cassette with it's supplied lockring. Use a bit of force but don't get silly. Brace it against the floor to help. You should feel it grind as you tighten it down.

You can then fit tyres and tubes and the fit the wheels to the bike. You may have to re-index your gears afterwards. Lots of vid on youtube explain this if you need them.

To expand, I'll be buying the cassette seperately, an Ultegra 12-30 as an upgrade to the Tiagra 12-30 I'm currently running. Might as well use the opportunity to change that out, especially if it makes installing the wheels easier.

Can anyone link me to the appropriate tools in order to fit the cassette? Might as well order it all at once

Also will the cassette come all in one piece to slot it on or is it built up cog by cog?

Edit: I see that has been explained above, thanks

PS I bought one of these toolkits from Aldi https://www.aldi.co.uk/en/specialbuys/s ... -tool-kit/ it says it has a 'freewheel remover' would that do the job to fit the cassette?

Hard to tell from the picture, but there does appear to be a lockring tool in the kit so you should be good to go.

personally, if it was me i would also change the chain if fitting a new rear sprocket, all new tyres, your fitting very nice and expensive wheels so you should shod them in the finest rubber.

"Can anyone link me to the appropriate tools in order to fit the cassette?"

I did just that a few posts ago...

Or were you looking for something a bit more expensive?

Re your toolkit, strictly speaking a freewheel remover has a subtly different spline profile. My guess is it's a cassette lock-ring tool. Impossible to tell from a small pic. I have trouble telling them apart and I have one of each. All I know is a cassette lock-ring tool is useless for unscrewing a screw-on freewheel. You might be able to tighten a cassette lock-ring with a freewheel tool, but it would be best to use the right thing for the job.

I've got that Aldi kit. The lockring tool you need is silver and just below the tyre levers. It fits the black end of red handled spanner. If you're removing a cassette you'll need to use the chain whip to hold it still.

Cool, cheers
