Thanxxx!
Not sure what to say 😕
but this might help you ?
Thanks for the video, but i was wondering, about the chain, i know there are 8/9 speed chains, 3/32, etc, but i dont know the difference?
MOST rear sprockets will work with any chain. There are a few that are specific to the BMX width chains but they will usually say so.
A 1/8 chain will drop less, if that might be an issue but won't work with a tensioner.
What seperates a 1/8 chain from the otter chains?
I do infact have a 9 speed chain lying around could i just use that?
I use cheap 8 speed chains on my MTB SS. Never dropped the chain.
I'd recommend the Shimano DX sprockets, cheap and hard wearing. Although I use a On-One Groove Amarda rear sprocket now, had a nice wide base.
What's your freehub body made from? You need a wide base on aluminium ones.
Thanx for the replies!
-the frehub is a wide alu, so no prob there 🙂
No. He means you will need a wide based sprocket if you don't want to chew up your alu freehub.
What seperates a 1/8 chain from the otter chains?
Size, It relates to width, 1/8" and 3/32" are the singlespeed/bmx sizes. These are wider than your 9 speed chain. Wider ones are generally stronger but heavier unless you go for something posh like KMC's Light.
Your nine speed will be fine though,
Sprokets:
Wider base: (slightly more expensive but less likely to damage your freehub)
Thin: (These easily dig into freehubs, esp hope)
I have had problems getting 9 speed chains to work on the 1/8" cogs but I do know of people who haven't so i'd probally to play safe go for a 3/32" cog.
Look for one to match your front ring, 32t up front and 16t at the back is a good start for 26" wheels, 32-18 for 29er.
