Singlespeed & Fixed Gear - New Front Cassette?

Ok. I love my singled speed trek now and I want to make the change permanent. I know I need to buy a tensioner (right now I am using me rear derauiller) I know I need a new rear cog(cassette I don't think is unassembleable). But My question is can I use the nine speed front chainring with a 1/8 rear bmx cog and a 1/8 chain? Or will the extra side to side chain slop damage the front chainring? Any replies are greatly appreciated.



Thanks, John

Using 1/8 chain on 3/32 chainring/cog is fine.
Might be slightly noisier but not a big deal.

Oh, and you can't use a singulator (chain tensioner) on a fixed ger so if the Trek has verticle dropouts, better buy an ENO or get a new frame.

I will most use something like a rennen chain tensioner.

If you are going to run a brake and never skid or skip, then okay.
But if not, then I'll repeat that you can't use a singulator/chain tensioner on a fixed gear.

sure you can. the singulator is designed for use on vertical dropout frames with a derailleur mount, and now have single speed freewheels.

Single speed, yes.
Not fixed gear.

They can't hold up to the pressure of skidding and skipping.

Even if you don't skip or skid I would not run a singulator on a fixed gear.

Thank you.
I was starting to think I was crazy.

uhm, he said its a singlespeed, and hes using a derailleur as his tensioner now.. so im pretty sure hes not talking about making a fixed gear.

You're not better than me!

Yeah, okay, I misread.
I for some reason took "make the change permenant" to mean "make it fixed."
Carry on...

I am not entirely clear what you are trying to do. Are you planning on buying a new rear wheel that is built for single speed use or just planning on using your old (multi-speed) wheel?

If it is the latter, you may be able to get away with not using a tensioner. Just buy one of those surly cogs and a bunch of spacers on your old wheel. You may be able to get the chainline to work and you can stick with a standard 3/32 chain (I would not mess with 1/8 unless you have to, especially for a free wheel conversion).

Try to find the magic gear so you don't need a tensioner.
