Description

For geography’s victims.

Remember "granny gear?" Like the fanny pack, it was useful, although the nickname had its negative implications. Also like fanny packs, granny gears are still available, although the plummeting demand dictates that their days are probably numbered. This poses a problem for mountain bikers whose nearby favorites fall into the category of "barely climbable." If you’ve ever wondered: What’s the absolute maximum number of teeth that my rear cassette can hold, shift into, and slow-pedal up that nasty 45-degree climb a mile from my front porch," the Wolf Tooth Components Giant Cog For SRAM has the answer.

40 or 42. That’s not a typo — 40 or 42 (your choice) friggin’ teeth. You could climb a tree with this thing. Bear in mind — the Wolf Tooth Giant Cog For SRAM only works with PG 1030, 1050, and 1070 11-36 and 12-36 cassettes or X0 11-36t (XG-1080) cassettes. Also, use of this cog requires the removal of the 15t or 17t cog and spacer from your cassette. You will probably also need a longer chain.

Durable, snazzy looking, and works as intended with minimal shifting fuss. Great product!

GRANNY GEAR

    So me being the idiot that I am, I bought my new mountain bike with a 1X10 drivetrain to save a couple bucks- let me tell you, that was a big mistake given how much I like to climb on my bike. So instead of switching out the entire drivetrain, I opted to put on this giant cog, and what a difference it makes! While it doesn't compare to SRAM's new Eagle drivetrain, it definitely gives you that extra boost for those long rides. If you don't want to replace your entire drive train, I highly recommend this!

    I'm currently running an 11-36t cog and looking to do some bikepacking. Given that my biggest cog is already 36t, would the extra 6 teeth be worth it? Any answers are likely to be fairly subjective; just looking for some outside opinions.

    If you are bikepacking you will most likely be carrying extra weight on your bike. Bags,Sleeping bags, food, extra water, maybe a stove, etc. I would recommend getting the bigger cog especially if the route has lots of climbs. I have a 42T in the rear and 30T in the front and my bike weights around 60lbs fully loaded with bike packing gear and I can still climb all day no problem.
