did TA make low-ish ratio front-outer chainrings? i have a TA (cyclotouriste style [TA pro 15]) crankset on my CB path racer, currently set up as a fixed gear with a 52x16 ratio. i am relocating to a much more hilly terrain, so am looking to switch to something lower, hopefully a 42, 44, etc.
so, did they in fact make outer chainrings ("outer" referring to anything that would match the inner 5-bolt pattern) in this smaller size. and if so, does anyone have one for sale or trade? i have an extra TA track (?) 52 tooth outer ring (not drilled for anything but the inner 5-bolt) for trade in return.
thanks very much
