    Redline monocog 29er gearing ?

    Hi, I tried a few search's and found some needed info, but still have some questions. The stock gearing is 32/20. I am going to mount Bontrager 700x35 Select K's. Will be used for communting. Mostly flat depending on route. One way is 1.6 mi plus whatever I add on going home. I think the crank is 104 spacing. The chain ring is currently on the inside of the crank and close to the chain stay. With a bigger chain ring, it will mount to the outside of the crank. How do I space the rear cog out to keep the chain in line? What type of cog and where do I get them?
    Thanks for the help, MikeB

    I know they used to come with a 42t, so assume that would fit...

    You should be able to get the gearing you need without changing your chainring. BMX cogs cost $5. Buy several and experiment.

    The biggest front ring you can use without swapping to the outside of the spider is a 36t; I know bc I just put one on my buddies Mono last week and it's the max size.

    But they do have a cassette hub, so as mentioned already, you can swap cogs and play around a bit. As far as chainline goes, a lot of higher end cogs out there you can flip around for a 2mm chainline change. My surly 3/32 rear cog on my DJ can flip around to give you an incremental chainline adjustment.

    I personally run 2:1 on my 29er: an 18t trials freewheel in the back and a 36t mono veloce up front. It kicks ass.

    Surly cogs are avaiable down to 13 tooth. That will give you 66 gear inches with your existing 32 tooth chainring and 35mm tires. A slick in the 2.2 inch range would up that to just over 70 gear inches.

    Thanks everyone, I think I'll start with a 36 or 38 up front and fine tune with the rear. I am just getting back into it and not strong at all. Plus we get some major wind here, did a ride with 25 mph head winds to get home. Took my road bike to work and was using the 39 front and 24,21,19,17 in the rear.Thanks again, MikeB
