110bcd 4-arm chainrings? Shimano replacements are ££££
French ones are good and much cheaper than OE, I wouldn't say there's anything to choose between Stronglight and TA. I assume you can also get Czech rings in modern Shimano pattern now, which would need to be a bit cheaper than the French 7075/Zicral versions to represent equal value.

Go for doval. Their "5g" are basically round (unless you fancy being adventurous, 4g is my fave) and they're pretty good for the price. I think the graphics can be acetoned off but haven't tried.
I've had a few sets on a couple of different bikes and haven't ever broken any. They used to do ebay auctions starting at a quid or so, I won a few sets at weird times of day for £2 or £3 plus £7 shipping so I'd just let the entire drive train wear horribly together and replace the lot after a few thousand miles. They'd last a lot longer if I changed the chain more regularly, I imagine.
Anyone used any orient 110bcd 4-arm chainrings? Shimano replacements are £££££
