    I have a 53/39 standard crankset legs and have gone down and weight has gone up , now 39 - 25 isnt cutting it anymore on the climbs.
    I dont want a stick crazy big cassette on , i like the smaller gaps in shifting and i dont like the look of it !

    Anyone know of any compatible chain rings that will work on the inner ring ??

    Any rings you get for DA7900 would need to be 130BCD. The compact chain rings are 110BCD. If you upgrade to DA9000 both standard & compact chain rings can be used.
    Or you could see if anyone is interested in swapping a compact for a standard, which I am😉....over in the 'parts for swap or trade' thread!!

    Ah right. I think the smallest 130BCD chainring that could be got was a 38T when searching some years back. Not sure if still the case.

    As calistro stated,38 is the smallest inner ring that will fit the 130 bcd on youre crank.
