    front chainring?

    I'm riding a modified motobecane fantom cross uno (link) and want to upgrade my chain ring. My problem is chain compatibility. I can't for the life of me find a chainring that fits (1/8" chain, at least 44t, 5 bolt, 110 bcm). All the rings are for 3/32" chains! If i were to get a new 3/32" chain and matching chainring, would I be able to ride without also changing the free wheel and cog on my rear hub? Raising my ratio is beginning to be much more expensive and troublesome then I want it to...

    3/32 width is thinner and 3/32 parts such as chainrings and cogs will work with a 1/8th chain.

    the cheapest, most readily available 110bcd chainring are the Origin8 ones.
    harris cyclery and one-eighth have them

    Alright, so I'll keep the 1/8" chain and cog and just get a front chain ring that is for 3/32" and run it with a 1/8" chain? Everything would still run smoothly? Thanks man!!

    Better off just changing your cog and not wasting money on that crankset

    i don't know if it's a good idea to keep the stock 38t chainring though.

    I need to change the chain ring, my freewheel is already a 16t and I can't find any english threaded 15t freewheels. Though origin8 makes a 1/8th ring that would work, I need a black one (whole bike is matte black, a silver ring on that wouldn't look good haha) thanks guys!
