Seatpost clamp size for a 29.8 seatpost

[atlantis]

Hi !

Could you pls let me know the seatpost clamp size, that I should buy for a 29.8 Seatpost. Unfortunately the availability in india is nil, I would have to go online for a purchase. I have already tried a 31.8 clamp and been unsuccessful.
If possible could I have a table for all the compatibility like : SeatPost size---- Seat post clamp. This would certainly help !
Pls advise

34.9 is the next size up, unfortunatly there is no table of compatability as all bike manu's use different sizes, all i can give you are the three most common sizes which are 28.6, 31.8 and 34.9.
