Chainring replacement /compatabity - Shimano

[Superlight-Andy]

I've just discovered a crack in the outer 50T chainring of my Triban Sora chainset. It's a 50/34 and I'm wondering what cross compatability for newer models there is. Iask because I've seen a few 10, 11, 12 speed rings or chainsets cheaper than single 9 speed specific ring. For aesthetics I'd like to retain the current appearance e which the modern Shimano rings/chainset appear to all have but I'm unsure of any fitment or shifting issues if I don't keep to the Sora/9 level. Both 50 and 34 are fairly worn so if I can cheaply replace both the that would be ideal.

If you have a 50-34 arrangement then I assume it's a 4-bolt setup (?)

This one looks pretty reasonable: https://www.bikeparts.co.uk/product...334&gbraid=0AAAAAC6PGhwUVb4EPD6A17CXNVeJc9KF4

Finding grey ones is a little more difficult. I gave up on that when I needed a replacement for my 3x Sora with 5-bolts

Pics or the model number (reverse of either crank arm by the pedal hole) would help

Try looking for Stronglight ones ,using the 11-speed versions and have been very good so far, but don't reckon 11-speed rings would play nicely with 9-speed.
