Reddit mentions of Park Tool FR-5G Cassette Lockring Tool with Guide Pin

Buy tools as needed, no need to stock up with everything right away. Most park tools I buy on Amazon and get them within two days. Tools I would get right away though would be

• 1" Crescent Wrench
  
• Park Tool Cassette Remover
  
• Chain Whip, for removal of a cassette
  
• Park Tool 3-Way (in 4, 5 & 6mm)
  
• A chain tool of some sorts
  
  As for cabling
  
  Universal Brake Cables on Amazon, just make sure you cut of the correct end.
  
  Here is a shift cable set.
  
  As for cutting the cables and housing, do NOT use standard wire cutters. You need a parrot style nosed set of cutters, like this Pedros set. I bought a cheap set of cutters on eBay that work great. When I cut housing I use a little sand paper to flush up the ends.
  
  The 4th hand is not really needed, I get by fine without it.

Swap this in using these tools and call it a day.

That will take you from a 3.69 top gear to 4.36. 18% increase at the top.

You linked to a freewheel remover. What you actually need is a cassette lockring tool.

You are correct -- the only difference between the 11 speed KICKR and the 10 speed KICKR is the cassette. They even share the same freehub, which is the thing the cassette sits on.

You'll need to replace the 11 speed cassette with a 10 speed one. You will need some special tools to do this, though. Are you having your KICKR delivered to your LBS? If so, I'd have them do the swap. If not, you'll need this (or it's cheaper alternative here), one of [these] these, and a large adjustable wrench.

After you collect those things, here's a nice video showing you how to do the swap. Instructions are the same even for your KICKR.

If you haven't already purchased a new cassette, get the cheapest one. Weight is of no concern for indoor training -- no need to be a "weight weenie." If there's any guidance to be had with choosing a cassette for a KICKR, I'd stick with the same gearing (i.e., if your rear wheel is a 11-25, get an 11-25 for the KICKR. That way there won't be any adjustment issues between the KICKR and your rear wheel.

Jesus, $85 for a tuneup? You got ripped off. Most I've ever paid is $35. Hell, the chain/cassette shouldn't cost you $150 unless you're buying absolute top-shelf components or you have a 10-speed cassette (And even then, you can do it for less). A chain shouldn't cost you much more than $30 for 9-speed, $45 for a 10-speed, and a decent cassette will run between $40 and $50 for 9-speed, $70-90 for 10-speed.

Don't know about the other parts, but definitely consider going to another shop for a quote. Also, the chain and cassette at least are super easy to replace yourself with minimal tool investment. All you'll need is a chain tool, one of these and a chain whip. The chain tool you'll want anyways, and chain/cassette replacement should be done every year or two, so the others are good to have as well.

You'll need a lockring tool and a chain whip. (You need the whip to hold the cassette in place and the lockring tool to take off the cassette itself. Park Tools is the brand I have, and probably the most reputable. (I'd link it, but apparently Amazon doesn't want to cooperate...)

So if I get this tool, I'll also need something like this chain whip and this cassette remover?

Thanks for the info!

those cable cutters suck.. try this Jagwire cutter

Bottom Bracket tools? like the BBT-22

Cassette tools? like the FR-5G

Also, it looks like you like to true your wheels enough to get a better spoke nipple wrench
