Where can I get a 33t chainring for an old 105 crank?I want to put the existing inner 42t on the outside and stick a 33t on the inside,its 5 bolt 130 BCD.
AFAIK the smallest available is 33tpigman":2ezrslnu said:smallest you can fit on a 130 bcd is 38 and that's a tight fit, normally its 39
you'd need a modern compact for a 33 I guess
