hey im trying to figure out what gearing to run on my riot frame. were sittin here building it up and in order to make the 36 tooth chainring ive got clear the chainstays it leaves hardly no spindle on the other side with the spacers on. ive got a 25 tooth chainring sittin here but the smallest rear cog for my hub is a 13 tooth. any help?

 

[wakeeater]

i'd say get a 30 tooth. or a longer spindle but 36/13 is a rediculously high gearing. 30/13 seems perfect to me

ya i dont have a 13 cog right now ive got 16. i meant i could get 13. but im worried bout buyin another stinkin chainring and it not workin either. nebody who has a blackmarket frame want to tell me their gearing???

What frame you have is irrelevant to what gearing to run.
You can probably get a 12T cog, I use one. Mentioning the hub you have might help.
I think I have deciphered part of your message. You have to add extra spacers to the spindle for the 36T to clear the chainstays. That's when you have "hardly no spindle"?
If you have 26" wheels, shoot for slightly higher than 2:1 gearing. I like 2.25 to 1 a lot (27/12). I would not recommend going much higher than that though.

25/12. And It just so happens that I have the 25t MDS off my Riot sitting right here...it's also on Ebayrightnowbutendingtomorrowfor$30gottalovespam.

ya reading back over that i realize i sound like an idiot. sry i tried to clear it up a bit. ya im sayin blackmarket frames cause i wanta know if people are runnin chainrings higher than say a 28 tooth and clearinthe chainstays. does the 25/12 not feel like a really high gearing?

 

[fiddy_ryder]

from what i remember from a friend with a mob, he was only able to run up to 30t on the front otherwise it would hit the stay.

Thank You

It's actually pretty low, compared to what I run now. It depends on how strong you are, and what kind of riding you prefer.
Remember, the size of the rings is irrelevant, it's the difference that is the key. Divide the large by the small and you have the gear ratio.

I have a mob set up with a 25/12, seems super good to me. I had a 13 on there but it spun out a wee bit to fast. If your doing lots of hills consider that route, but IMO that 12 is perfect.

I've got a 34t on an xt crank on a mob, but yeah I had to space it over a bit and there is less spindle on the non-drive side than I would like. I can see that a 36 would not fly, the 34 barely works.

im running a 33 with primo hollowbites. eventually i will build a wheel with an odyssey hazard hub with a 9t driver and my 22t ring.

 

[t1maglio]

Just a quick question to Arboc, how do you use a Hazard hub on a MTB, the spacing is different?

 

[arboc!]

well... sort of ghetto half-hazard hub. its like a love child between an eastern mtb hub with hazard internals.

i have a mob... i use a 36/16 which is a little high... but it's dialed for my riding and my local spots.
