I put some new bling on my Karate Monkey.
It’s a little hard to make it out in the picture, but it says “36t” on the big cog.
That’s the much ballyhooed Shimano SLX HG-61 cassette. With my monkey’s mountain triple (FC-M460) cranks, I have stupendously low gearing (in inches):
The lowest gear is 17.8″ For most people, this is probably insanely low, but I am not like most people.
I am fat, lazy, and slow. And I live in a mountainous area. I suspect that low gear will see lots of use.
Shimano say you need a fancy “Shadow” derailleur to make this cassette work. Shimano are full of it.
This is just a regular Deore derailleur. I screwed the B-tension screw all the way in, and it fits. Just barely.
Shimano also warns you that the 22/36 combination can generate so much torque that you might damage your rear hub. They then suggest that you should buy one of their fancy 29er-specific rear hubs.
I think I have the hub situation well in hand already.
I took it for a test spin around the block today, and everything seems to work. Hopefully, I’ll have a chance to take it out to the woods this week and see if I am able to spin up some hills that I have had to walk up before.

Awesome. How fast do you go in low gear? 2 mph?
According to the Sheldon Brown gear calculator, if I can spin a 90rpm cadence, I’ll go about 4.8mph.
So basically, it takes 20 minutes to go 3 feet… straight up.
I’ve got 22.x34 and I’m surprised how much I use it.
