    Two rear cogs on XXIX

    Hi my xxix has the rear cog with the shimano bmx type (non threaded). My question is if i can add a second cog butted up to the existing one with a spacer in between. I saw that surly makes a dingle but its a track cog. The chain i have is a slim one 3/32. Do i need a tensioner?

    Thanks!

    If the bike has horizontal dropouts then you should be fine using them to achieve proper tension. If not, a tensioner is probably your best bet

    What about the dual-cog freewheel from White Industries?

    Those are for srew-on hubs, not for cassette style hubs.

    You can put a second cog on the hub, but you will need to deal with a difference in chain length for the different gearings.
    You might consider a dinglespeed. (*runs for cover)
    Ride more!

    Darn right you better run for cover. Kidding. Actually you're not the lightning rod in this situation. Once the OP puts a second cog on his hub, he's crossed over, regardless of the number of rings up front.

    It's no longer a singlespeed.

    Not that there's anything wrong with that.
