Please help me find a 34 tooth 74mm bcd granny gear that works with 9 speed.
I have a "Sugino Comp" 52/42/30 triple (130/74mm bcd) that came standard on my 2008 Allez, which is a 9 speed. I'd like to replace the 30 tooth granny ring with a 34 tooth, but these seem to be difficult to find in 74mm bcd.
I've seen there is a TA 34t 74mm bcd available from Harris, but it's a bit expensive ($43). There are also some 34t made by Sakae available on ebay for $12, but I'm not clear if any of these will work with 9 speed chain. Any experience with this would be helpful.
From the listing:
This is a SR Sakae "300T" 34T alloy inner sprocket for triple chainwheels. The hole center to hole center is 43.5mm and the bolt circle diameter is 74mm. This sprocket fits SR FLC-T310, FXC-T310, SXC-T310, AXC-T310, CRC-T301, CXC-T300, SAC-T310, SXC-T200, Takagi Tourney GS & XT Cranks.
