    Swapping components - via ebay? Fair prices? Warnings?

    I'd like to sell the Shimano 105 components that are coming on my new 2010 bike on ebay and purchase Sram Rival instead.

    Since my shimano parts are coming off a frame (well, the bike will arrive unassembled in the factory box, so I'm not sure if most of the parts are on it already), what can I expect to receive on ebay for them? What will buyers need to see in the description to know they are getting what they want? I'd prefer to sell as a whole group. Is there any difference between OEM and retail (aside from warranty loss?)

    Then..when I go to buy the sram rival, what do I need to pay attention to?

    I've bought & sold on ebay many times, but never for anything bicycle related.

    I know next to nothing about bike mechanics.

    What gave you this silly idea? Why not just buy a bike with the group you want? It will cost less in the long run and you won't have to venture into regions you know nothing about.
    Stupidity got us into this mess - why can't it get us out?

    1. "...what can I expect to receive on ebay for them?....What will buyers need to see in the description to know they are getting what they want?" Check ebay for previous sales (but real answer is whatever successful bidder is willing to pay).....include specs from manufacturer.

    2. "Is there any difference between OEM and retail (aside from warranty loss?)" Probably not - ask the manufacturer

    3. "Then..when I go to buy the sram rival, what do I need to pay attention to?" If you don't know this why are you already decided on sram??

    4. "I've bought & sold on ebay many times, but never for anything bicycle related." Not really different

    5. "I know next to nothing about bike mechanics." Then you should not be trading out parts on a new bike - you neither know your true needs/preferences nor what you will need to spec.

    Moefam, what your proposing will not be worth it, for several reasons.

    Despite what different people will tell you, the difference between SRAM Rival and Shimano 105 is very slight, if anything. There are functional differences, and you may prefer one over the other, but if that is the case you should just buy what you want.

    Buying a bikesdirect bike, for example, stripping off the 105 parts, then buying SRAM Rival and putting those on the frame you just bought is a pretty massive effort, especially when everything you have is new and will probably only need very minor adjustment.

    SRAM stuff is more expensive because it is hard to find on discount. If you sell your 105 stuff on eBay, you might be able to recoup most of the cost of the SRAM stuff, but you will have made a nearly linear move in quality with a huge time investment.

    Since you say you know next to nothing about bike mechanics, this would be a particularly massive undertaking. Don't do it. You're more likely round off a bolt, overtighten something, or not get something properly adjusted than you are to see any benefit of making the switch.

    Just out of curiosity, what made you want to switch to Rival?

    +1 Search ebay history. Since you are experienced on ebay, you are already aware of the tremendous variance on ebay. The same item, at the same time, can sell for 1X, 2X, 1.5X and .5X. I see it all of the time. The bidding is very uneven. So I would not count on getting a number.

    +1 If you know nothing about mechanics, I would skip the entire process. Keep the bike with its original parts, or buy a bike with the SRAM parts you want. Paying someone to do the work (both the take off and reassemble) will not be cheap. Its best suited for someone with the time/tools/aptitude and interest in wrenching on bikes.

    As far as a difference between new and buying take offs on ebay, which would you rather buy, and where would you pay more? Would you pay some unknown person on ebay, who claims the parts are brand new, or would you rather buy brand new stuff from a local shop, or via the internet? I think the answer is pretty obvious.

    Brifters are an area on ebay that is really buyer beware. It would be one of the last parts I would buy on ebay. It would have to be a smokin hot deal for me to consider them. Full disclosure: I bought a mini-group of nine speed Ultegra last year on ebay, complete with derailleurs and brake calipers, handlebar, stem, both brifters, and cables. But the seller really botched the listing, and I paid about what the two derailleurs used would sell for (buy it now auction). Turned out the front brifter was a little balky, but I got it working. And at the price, it was a great deal regardless.


    Right now, there are some really good deals on brand new drive train groups on the internet (European sellers). The drop in the Euro and the pound have made some of the deals compelling: Probike Kit, chainreactioncycles, etc.

    EBay may or may not bring you good deals - it clearly illustrates the law of supply and demand. Try to find an original old-style Cinelli stem, for example - you'll see people ready to pay prices that have nothing to do with the value of the object they're buying. I fished around a couple of years ago for a pair of Speedplay pedals - and let go and bought new, most auctions were ending up above MSRP... The price difference between used bikes of well known brands in the US (Trek, Specialized, Cannondale) and lesser-known brands is another easily verified example.

    In your specific case, you'll probably lose out - you'll be selling a high-availability set of parts (Shimano 105) and looking for a lower-availability kit (SRAM Rival). Supply and demand says you'll pay more than you'll get. Not to mention your self-admitted lack of knowledge in bicycle mechanics. Unless you have a lot of money and a lot of time to dispose of, you should buy the bike you want rather than trying to piece it together. At the limit you'd be better off selling the new bike on eBay and buying another one...

    Hey thanks for so many great replies!

    Here's a little more about my intentions. I tried out a bike with the sram rival and immediately loved the double click and the smaller shape of the hoods. (I've got the typical long legs/short arms & hands girlie problem.) My current bike has Tiagra components but the bike is a poor fit. The bike I am buying is a very good deal and to get that same bike with rival, I'd be looking at spending another $1,000 at the LBS. My LBS is quoting me $60 to assemble the new bike, so I figure if I just have the sram put on from the get go, the cost to buy a new group ($550ish off ebay??) seemed do-able if I'd get about $300 for the 105 parts.

    I was trying to establish if there's more than just listing the parts or if there are sizes that I need to know in order to correctly describe the item. (For example, I know its 50/34 compact, 170mm crank...but what other "sizing" is there?)

    But...from the sounds of it, I'm blissfully unaware of the complexities involved to do this - regardless of how affordable or nice my local LBS mechanic might be. Assembling a bike from the factory is not the same as swapping all components - something I didn't reailze before.

    I sure read a lot on here how much nicer sram rival is over 105, lighter, repairable, and comparable moreso with Ultegra. For me, I just liked the feel of the small hoods and how it shifted...that's really about it. It's not enough to justify dropping the extra grand on one already fitted with the sram. (besides, I like the 105 bike's colors better!)

    Oh..and while I may be completely clueless now, I'm not exactly untrainable. I find this stuff interesting and am motivated to learn, I guess. It sure beats making debits equal the credits at my 9-5.
