[Closed] A Really Low Gear.

Of course it's possible. I just put a 20-33 double on my fatbike today. A crawler gear for deep snow and for climbing impossible stuff is ideal.

Of course.

what ring/crankset?

Surly MWOD but 20T rings are pretty widely available. Middleburn do them for example

Edit : need a 5 bolt crankset

How's the pneumonia lad?I,ve got a stinking cold that I am praying doesn't go the same way?

Smallest these guys sell is a 18 thooth

"try and replicate this hopefully "
The closest/easiest replication would be most 'triple' cranksets and use a 22T granny ring, then the 36T casette out back

Obviously if you'll rule out all but sqaure taper* then you have the option of a 20T

*middleburn 5arm and some others. I'm assuming all 20T options mean square taper cranks? (or a BMX style 3 piece single ring?)

I keep thinking a lower than 22-34 would be useful sometimes. Though not wanting to splash out to 10spd, have an alu. freehub and prefer the stiffness of a HTII bottom bracket I think I'm stuck as I am

EDIT: is that link talking about 16 and 17T rings?

I've successfully fitted an Action-Tec 20T ring onto Shimano LX (I think, might be XT) cranks - 4 bolt. You have to file a small flat on the boss they fix to, and I think I also added some washers to get the ring far enough from the middle ring. I've also (on the same bike) taken the 11T off the top end of an XT 11-34 and put an Action-Tec 39T on the other end to get a 12-39. I don't remember any problems getting this to work with a standard mech.

I'll admit I like mashing big gears but with 20:36 aren't you going so low that you'll expend more effort trying to balance than moving forward?

Might as well get off and walk....

I guess it depends if you're laden. Pushing can be very hard with a laden bike.
It also depends if you value riding over walking for whatever reason. On soft sand, it might be harder. Also on ice, if you have spiked tyres.
Or it might just be fun!
