    What cog to run for PMBAR

    I've read it is highly recommended to make last minute changes to your bike just before a big event. I am going to take it even further and just ride a bike (my SS) I haven't been on in 6 months that way everything is different than what I'm used to.

    I have a 32 t up front and am running a 19 which is ok for short rides here in TN, I am considering throwing on the 20 t (46.4 gear inches)or 21t (44.2 gear inches) for PMBAR what say yee who have ridden a SS in PNF?

    32x20 on big wheels if you're looking to win.

    I find a 32 X 22 to be enjoyable for most of my SS rides.
    I will be racing on gears, however.

    How much do you weigh (on the bike with gear)? I think that's got as much to do with it as anything else. I bet nearly all the <20's weigh less than 160 lbs and I'd guess this scale is fairly accurate for full-time single speeders.

    <160 lbs = 19t
    160-175 = 20t
    175-190 = 21t
    205+ = 23t

    I'm @ 200lbs and need to run 22t for a reasonable walk/ride ratio when going > 30 miles. You spin a lot at first but you like it later on. That said, I love 20t for short <15 mile rides and 21t for 15-30 milers but if I was just riding Squirrel for kicks I'd choose 22t to stay on the bike more. Lots of variables eh?
    many gears, some pies

    I've got my eye on a new 60T chainring...

    and a new 12T cog that can handle my massive amounts of torque.


    I get paid 3 every time I post on MTBR.

    I was in Pisgah for the first time a few weeks ago, just to check it out for PMBAR. I was using 32:20 on my 26er and will likely go with it for the event. I thought all the double track climbs were doable, yet I am thinking in wet rainy weather, maybe I would enjoy my day better with a 21t. Then again, I don't thing I should be using the word "enjoy" when talking about doing my first PMBAR.
    Here's an idea -- Bring both and swap on the trail if needed.
    I no longer deserve a signature. :skep:

    That would feel like cheating.

    I enjoy every day I am on the trails in Pisgah. No matter how much it hurts.

    That's BS Tomato! Don't go blaming your gear choice on my alias.

    If you are worried about what gear to run, just put on a derailleur. Otherwise man up, or in my case, woman up and run a 47" gear if you want to win.

    However, if you are out to sight see, ride safe, and your partner is prone to breaking things, you may want to ride a 40" gear.

    And what is this crap about if I weigh 150 then 19, 160 then 20....?
    How does that equation work when you carry a six pack of Natty in and plan on drinking at every check point? Should I average my weight with gear based on time in the saddle, blah blah blah.

    The cold hard facts are that at least 5 people die each year during this event. Quit worrying about gears and start figuring out how to pack some heat. I hear the mountain lions are hungry this year after the hard winter.
