Help on choice of chainring

mabbo

All, I need to replace my outer chain ring. I am on my original Shimano Hollowtec 50T. 10 speed, 5600 series I think. 130mm BCD. So.....it seems I have a number of choices. Anyone had any experience with the Sronglight Zircal rings? Or the Pro series available on e-bay?? Or how about FSA?

Anyone got any advice on best to choose at a reasonable price? Maybe about £30 ish? Obviously if I can improve on the shimano, all well and good.

Id probably lean towards Stronglight if not direct Shimano replacement...
