Hello! This may be a dumb question, but I need to ask it so I can save a few bucks.

I have found a 7800 53t b type chainring deal (64€), but 39t (29€) is out of stock, but there is a 7900 39t b type chainring (also 29€) in stock.
Are they compatible??

Thanks very much.

P.D. In other shops I can get the 39t for 3x-50 + shipping.

If the bcd (bolt circle diameter) match, it should work.
