Hey fellow GT Owners!

I ran a few searches in here, drivetrain forum, and general forum but didn't find what I was searching for. I use my Avalanche for paved and hard packed paths, was interested in converting it to a single speed setup. I found a couple kits for the rear cog on Jenson one is half the price of the other, single speed chain is only $5.99.

My question to those who have done this is:

1. The setup is currently an 8 speed chain, rear cog/gear kit says compatible with an 8 speed chain. Do I need the single speed chain and tensioner they recommend?

2. What do I do with the front crankset? I've taken the big ring off my AM bike, is this similar but I just need to take off the granny sprocket too?

Thanks for your help!

Assuming you are not using eccentric bottom bracket (EBB), you will need a tensioner, else you drop your chain with every bump and crank rotations. If using on flats, then 2:1 is a good start. Meaing rear teeth * 2 = front teeth, 16:32 as 32 chain ring is very common. Take off small and big rings. Visit SS forum and you'll get more specific answers.

whoa krazy long time no see man. I've been on MTBR since the 90s (h-t days)

I have an old GT RTS with a SS setup. You don't have to use a SS chain, I've had 0 problems using a regular SRAM (and previously Shimano Mega9 chain).

I had an old chain tensioner that broke, and now I use an old Deore XT rear der. for chain tension.
