First, I promise I conducted at least a semi-half-assed search to see if I could find this info anywhere else on this forum. My apologies if a similar thread already exists or if this is the wrong area to post this thread.

I recently had my front and read wheels stolen off my road bike. Yeah, I know ... lock 'em up. I'm stationed in Korea and I figured the bike would be safe enough if I just locked the frame. Apparently, I was wrong.

Now I'm in the process of figuring out what I need to buy to replace both wheels. The bike shop on base only sells whole bikes and a few accessories. It's not big enough to really sell parts. And they don't speak English. So, I'm trying to buy replacement parts on Amazon.

The bike is mostly Shimano Ultegra (6600), including the rear cassette. Would this work to replace everything?

Shimano CS-5700 105 10-Speed Cassette
Amazon.com : Shimano CS-5700 105 Bicycle Cassette (10-speed, 12/25T) : Bike Cassettes And Freewheels : Sports & Outdoors

Would I need anything else?
Any issues with using a different cassette? The old one was 12-25T, so that's what I plan on buying again.
Will I need any special tools to try to install the cassette myself? Or, do you think I could I just bring the parts to the Korean bike shop on base and they know what to do?

Thanks!

You will need a cassette tool, like a Park FR5 (& a 22mm socket/wrench) to install, otherwise, you have all the part in the 2 Amazon listing to replace your wheels

As well, unless your chain has very little mileage, it would be normal to replace it when installing a new cassette

Yeah, and if you ever plan on removing the cassette you'll also need a chain whip. They don't cost very much so you might as well buy the cassette tool and chain whip as a set.

Take everything to the shop as you should torque the cassette lock ring, they will figure out what you want from the parts. If you want to deal with the tools, first study the Park Tool web site which will show you everything you need and how to do it.

If you plan to replace the chain you will need a chain tool to shorten it and re-close it. I use chains from KMC or SRAM which have master links to close the chain, but it will still need to be correctly sized. Or find a shop to do it for you.

Yes, to 40Nm, this is printed on the lockring supplied with the cassette.

Thanks for all the advice, guys. Chain has about 350 miles, so perhaps a new one might help. I think I'll initially just buy the parts and bring them to the Korean bike shop. If they can't fix it, I'll be coming back to the US in about 2 months and I'm sure there's an lbs wherever I'll go that can do it.

350 miles? Your chain is almost new. If that is accurate, there is no need to replace it unless your new cassette has a much larger biggest cog

Good price on the wheels. The Claris is a couple of steps below your current Ultegra, but at least it is new.

The Continental Ultra Sport tires are also some of the bottom of the line Continental tires. I haven't used them myself, but they will be a bit lower quality than some of the more popular Continental models.
