Dumb noobie question re chainset

    Just thinking of having a go at this fixed business, looking to try it out cheap...can I get a regular 42/52 chainset off ebay (they're always the cheapest) and take off the 52 ring and combine the remaining 42 with a 16t rear sprocket and away I go? (From googling, 42/16 seems to be a pretty standard starter combination). Thanks for any advice.

    The only problem I've had with a non-track chainring is that some of the teeth will be shorter (to help the chain move off the ring), and therefore if your chain is a bit slack it is more likley to jump of than it would if you used a track chian ring.

    Thanks for that. I can simply remove the larger chainring and leave t'other in place tho', yes?

    Yes, basically.
    I did more or less the same as you, only I took off the inner chainring and ran 53x16*. I was on singlespeed, not fixed, with a conversion kit on the rear end, but so long as you get the chain line and tension right you'll be fine.


    * - I don't do twiddly, but that set up was a bit too manly for Devon hills. Even Chuck Norris would baulk at that. I'm on 46x18 now. Much nicer. :smile:

    Oooh, forgot to mention. You can get half width chainring bolts from HubJub (very fine online shop, nice to deal with :smile:) which may come in handy for what you want to do, seeing as the standard bolts will be designed to go through two rings. £5.50 a set.

    When I built my fist fixie I ended up using a load of washers behind/infront of the chainring to give me a straight chainline.

    You need to be carefull which bottom bracket you use and how you mount the rear sprocket.

    or you can save your money and simply make the original female parts shorter with a countersink drill bit.;)

    Thanks for the link Chuffy - I cut bits off an old chainring to make spacers so the single ring would fit on my double crank mountings. Looks an absolute dog's dinner!

    After one painful ride up onto the Haldons I went shopping for a smaller chainring....:sad:
