Anybody have experience with using an aftermarket chainring with shimano as I would like to know what brand, if any, 36 tooth chain ring is compatible with shimano 7900 crank? Thinking about upgrading to 9000 36/52 crankset but would like to demo the 36 on my bike first.

I have had the Praxis 52/36 rings mounted on 7950 crankarms...these are 110 BCD and don't work on 7900 arms (130 bcd)
2011 Tarmac Pro SL3 Project Black (gone but not forgotten)
2012 Parlee Z5 SLi (just because)
2014 Colnago C59 (why not)

a 38T is technically the smallest you can engineer on a 130BCD. Any smaller the CR bolt is directly in the tooth bed.

My bad I meant the 7950.

I own shimano's 36t. (110) from their CX cranks (fc-cx70).

Works a treat, but might be heavier than DA (but quite impossible to find though).
