Hey guys
I'm looking to run one of these on my next build :daumenhoch:

But think they look a bit pants with standard chainrings :-\

I want to expose as much of the slots as possible so hoping i can run something 130 bcd like this

Obviously these are designed for the smaller chains but can i run a larger chain on them or is there a bmx alternative to this chainring? :-\

All old school chain rings will take a standard 1/8 chain unless stated Clint. If you ran a 3/32 ring on the front, you would also need a 3/32 freewheel as the chain slots are too slim.
You can run a 1/8 chain on everything but the 3/32 chain is too thin to run an standard 1/8 freewheels and chainrings :daumenhoch:

Cheers Terry :daumenhoch:
Was just concerned the 1/8 chain may feel a little slack on a 3/32 ring and have some lateral movement :-\
-
Why not put the chainring on the other side like Brett did on this one:

I did think of that but all it does is make the non drive side of the bike look pants :(
Im just fussy about certain detail :LolLolLolLol:

Try a tuf neck/ pro neck/ PPP non slotted chainring, generally look less pants!

No mate. I ran a 3/32 Suntour freewheel on my GT Pro Series which I got off JT. I looked into it before buying it as I was a little concerned over the sizes myself. All 3/32 gear will run a 1/8 chain mate, just not the other way.
The difference is not that great a deal tbh :daumenhoch:

Magic :daumenhoch: Off to a roadie/fixie bike jumble soon so will keep my eye out

Mmmm. My 36T Porkchop chainring is 3/32" and it does creak with my 1/8" chain running round tbh..... :-\
