Can I use a Shimano 105 10 speed BCD 130mm 52t chainring as a replacement in my 9 speed tiagra triple crankset? I currently run Tiagra triple 9 speed crank, 50/39/30
The BCD on the 50 being 130mm.
I'd like to replace the 50t with a 52t to make it 52/39/30.
I'm looking at a Shimano 105 52t chainring but it says it's intended for a double crank and 10 speed drivetrain.

But you think I can make that ring work in my setup?
Should work fine, assuming the BCD on the 105 52t chain ring is also 130 mm (and not 110 mm - compact).  The 105 chainring will be profiled ever so slightly thinner for the 10 speed chain, but will not affect 9 speed performance. Make sure to orient the new ring in the correct position with the small metal tab (that catches an errant chain)  pointing  toward the crank arm.
