|  Does anybody make 36t chainrings compatible w/ Campy 10s ? | PeterRider Jun 22, 2003 5:09 PM | | I would like something a bit lower than 39t, but higher than the usual 30t. Does anybody make something like that ? For example, coming with my Bike Friday w/ campy 10s I had 48t and 60t rings made by Specialites TA.
Thanks !

|  Road bike chainring bolt diameters: | Alexx Jun 23, 2003 4:06 AM | | The problem with road rings is that, with a common bolt diameter of 130 mm BCD, you won't be able to find any ring smaller than 38 tooth. A 36 tooth ring would be just about exactly that for an outer diameter.
Touring bikes, OTOH, usually use a 110 bolt diameter, and 36 tooth should work there without a problem. Whether that would work with campy 10, I don't know... |
|  Campy BCD..... | Rusty Coggs Jun 23, 2003 4:37 AM | | is 135mm for the big and middle rings.Smallest chainring that fits it is 39 tooth. |
|  What is the BCD on the Campy triple inner ring? (nm) | TFerguson Jun 23, 2003 6:01 AM | | |
|  74mm (nm) | Rob Sal Jun 23, 2003 8:57 AM | | nm |
|  OK, so what I want is 36t with 74mm BCD (triple inner ring) | PeterRider Jun 23, 2003 11:16 AM | | sorry my initial message was not clear, this is to use as an inner ring.

Though I may still be confused, I think you have a Campy triple that you want to use 36, 42, 52 teeth rings. (I assume that Campy normally has 30, 42, 52 like Shimano) I wouldn't think that it would have any problem shifting. Be sure that there is enough clearance between the new, bigger inner ring and the chain stay.
