    Yes.

    You can likely recover a fair chunk of change selling your old stuff on eBay.
    I was surprised to see the 105 11 speed shifters are actually cheaper than the 105 10 speed ones.

    Maybe I should have looked into this option more but the thought of a new rear wheel and/or rear hub conversion scared me off.

    And I've now pulled the trigger on all the 10 speed gear with the exception of the cassette.

    Below is the full part / price list. Price might go up or down $5 or so depending on a few eBay auctions I'm waiting to end but at this point it's pretty set.

    Thanks to all for advice and input!

    Will update thread with pics once everything arrives in the mail and I've had a chance to install the gear.

    Tjc4,

    That looks really cheap for a cable and housing set. Check to make sure these are stainless steel cables. Many cheaper cable sets are galvanized. Galvanized cables will oxidize causing them to become rough. Rough cables can bind inside the housings causing poor shifting.

    This is not a place where you want to go cheap. You can have the highest end components in the world and if your cables are crappy, your shifting will be crappy.

    I ordered what was listed as Shimano "Stainless Steel PTFE coated cables" with "4mm SIS-SP41 housing." link

    But this is what I received.

    I now note it does not have the PTFE cable icon, it only lists the housing as SIS (not SP41), and I see some of the Amazon reviewers state they also got the cheaper stuff

    Thanks for pointing that out. I otherwise probably wouldn't have noticed. Sounds like I should return this and get some better stuff.

    Edit / Update: just ordered what appears to be some authentic PTFE cable / SP-41 housing off ebay for $22.

    PTFE is not as big an issue as stainless steel. Stainless steel is a gotta have. Yep, return it and get the good stuff which will usually cost $20-25.
