I've got a 10-year old bike I'm trying to revive. It was a single speed that I converted to a fixie. I'm anticipating just casual riding on flat ground.
It has an old-school looking Shimano SGX 46t chainring that I reused plus a Avenir fixed gear cog 1/2 x 3/32 16t in the back.
Because I'm not sure what type of chain the Shimano part takes, I'm inclined to do a 1/8 chain. The one thing that's holding me back is it looks like the offset between the chainring and the rear cog is around 8-9mm, which seems kind of high. I haven't figured out if I can include some rear cog spacers to reduce that, but I've read 3/32 chains are more flexible and forgiving.
I just don't know if my front chainring can take 3/32 and I can't for the life of me find any information on that chainring.
- Is the offset enough to be unsafe and I should figure out some spacers?
- If the Shimano SGX accepts 3/32, perhaps the increased flexibility can account for the offset?
- Or just get a 1/8 chain and be done?
Happy to add photos or additional information if it helps others to help me.
