    Help me pick out bottom bracket + crank + rear hub for salsa casseroll SS/fix build.

    Hey all,

    So been riding a steamroller for a bit now and getting ready to build up a new bike for my now longer commute and longer rides. I bought the steamroller as a complete, so I didn't have to worry about anything when I bought it for the most part.

    I settled on the salsa casseroll frame.

    Front Spacing 100mm x 9mm QR
    Rear Spacing 130mm x 10mm QR
    Bottom Bracket 68mm English

    So I am assuming I need a 130mm hub no questions asked for the rear? And come to realize 130mm hubs in a fixed / free are kinda of rare. Which makes since since 130 is road spacing and 120 is track spacing.

    I was actually planning on using my wheels currently on my steamroller, but with the 120mm rear hub, that isn't going to work. Unless there is some kind of hack where I can add spacers to make the hub the right size?

    On the other hand there is also chainline. So I guess I need to figure out what is going to work. I have been reading around sheldon's site and the information there on chainline is overwhelming.

    Isn;t there an easy way to know a certain combination of parts is going to work right? For example, lets take white industries since they make a 130mm hub. If I get white industries 68 x 113 bottom bracket, white industries crank, white industries rear hub, and white industries freewheel. How can I know this will give me a correct chainline? Just using white industries as an example, they are on the pricey side.

    Any help would be appreciated. So then I can just pick out parts with confidence.

    Thanks in advance.

    You don't need a new hub, just add spacers to your existing axle. If you buy new wheels you can purchase them already spaced for your dropouts. If you want to use your existing wheels you can purchase the aforementioned spacers. I'm not sure off the top of my head what sizes you'd need but 120->130 is a common thing to do.

    WRT chainline; the chainline is generally set at your rear hub. The majority of fixed/free wheelsets on the market are made for a 42mm chainline. When you purchase your crankset, purchase the recommended bottom bracket for fixed gear or single speed use and you'll be fine. If it's a popular crankset you can generally find the specs for recommended spindle length for a 42mm chainline and buy separately but it's generally easier to just get everything at once.

    e.g. here's a page where you look up a track crankset and it will tell you what spindle the crankset is designed for:http://businesscycles.com/tr-refspec.htm#b/b

    Here's an example of a crankset for sale at a retailer where the spindle length is give a range recommendation:

    I'm running a frame with 130mm rear spacing and Surly 120mm fixed/free hub. Not sure why you couldn't since the 130 chainstays are put to that width to accomodate a 135, 130 or 120 (giving you the ability to run any combination - hence salsa/surly/handsome/all city's design all along).

    The Q factor was too narrow for SRAM Omniums on my Devil frameset - make sure you're not going to face the same issue with the Salsa frame.

    I'm running a R700 with Sugino chainring w/ 105 BB30 bottom bracket

    When you say the Q factor was too narrow, you mean the crank arms were hitting the chainstays? Hopefully there is a way to check this before actually mounting the part. Would hate to spend $200 - $300+ on a bb + crank only to see it doesn't work.

    Ugh, bikes are more complicated than cars at times.

    The 130 spacing is meant for a 130 hub. The handsome and cross check are set to 132.5mm to accommodate either 130 or 135 spacing. 10mm is significantly more than 2.5mm. It would likely not harm the frame assuming that it's steel but it would be a pain in the ass every time you tried to put the rear wheel back in the droupouts. Also, unless you are talking about a different bike that you have, you are not using a BB30 bottom bracket because 1) the handsome devil has a threaded bottom bracket shell, BB30 is a press fit system, 2) shimano doesn't make a BB30 crankset.

    Also, what all city are you talking about? The big block is spaced at 120, nature boy at 130, mr. pink at 130, and the space horse at 130.

    You're right about the BB. For some reason I keep thinking about my CAAD9 when I talk about 105 components.

    I swore the Space horse was at 132.5mm (which is what I was rambling about when I said they were 130mm).

    I could take the low road and say I was drunk, but really, I was just wrong. It happens.
