Hello friends, I have recently built up a bike with TA style chain rings but they’re a bit too large for the type of writing I will be doing. Does anybody have any chain rings that they can sell me looking for a 48 to 46 outer and a 30 to 28 inner Thanks

If all else fails, try Peter White Cycles in New Hampshire or ebay...
Stronglight and other ring makers also made rings for 50.4 mm BCD cranks.
