Hey all,
Long time reader first time poster. ]
So, I've decided that riding only road bikes is boring and am putting together a little single speed MTB for the woods.
I've always rode a single speed bike (BMX and road) and would like to stick to single speed MTB too.
I have a On-One 26" single speed frame and am looking to get some cranks with it.
Am I right in thinking that I can just buy a double or triple ring, get some short bolts and pop in a single speed ring? I have had a look at some crank sets and some look like it would like kind of ugly to turn a triple into a single.
If anyone has any suggestions on which cheap(ish) sets would make a decent single ring conversion I would be very appreciative.
Looking forward to seeing what you peeps have to say!
Basically, as you suspect, any crank will do
I have no advice on what will look nice
You don't have to have a single speed specific ring, just narrower chainring bolts.
SS rings are betterer though.
Oh ok, good to know. So if I am smart I can just get a cheap double/triple where one of the rings has the number of teeth I'm after. Then adjust the rear cog to get a nice chain line, or if I spend a little extra I can get a single speed ring.
I have noticed that the teeth on geared rings are a big thinner and have some interesting cuts on them, which I guess allow for the chain to pop off easier when shifting.
I was expecting this to be more complex, but happy to hear it's not! Thanks for the help chaps.

These are the websites that will tell you/sell you what you need.
I'd deffo go for SS cog and ring, otherwise you'll be dropping the chain all the time.

If you buy a double chainset, you won't need extra bolts, as those supplied are single ring for the outer anyway-the inner is a different BCD & has separate bolts.
However, a triple generally gives a slightly better chain line.
As people have said, it's a doddle to convert. Ive got a SS hub converter somewhere in anodised red, a 17t rear cog and maybe a chain that are all pretty new if you're interested? Email in profile mate.
Oh and for cranks I'd just choose something with a 104 BCD. Deore, SLX are always knocking about cheap on here eBay and pink bike.
Great info everyone, thank you. I think I will pop down the local LBS and see what they have second hand. I'll make sure to get a new front cog too.
While I have your attention....
I'm also getting some 26" wheels for the first time. As this is a single speed frame with horizontal drop-outs I'm guessing that threaded axle is the best option? Paired with some chain tugs.
From the MTB's I see most often they all look like quick release hollow axles. is it common to see 26" MTB wheels with threaded axles? Or is this a case of make my own wheels up?
ps - jonnytheleyther : Thanks for the offer but I already have a converter, it's one of the only spares I have from past bike building adventures!
You can always add a bash ring in place of the outer ring?
