52/42 or 50/39
I am fixing up a Carrera TDF 2012 that I picked up for £10 in awful condition (a decent frame & handle bars, with a mangled chainset attached). I don't want to spend much money on it and don't need to win any races, although I might enter a sportive eventually. I've used a bunch of old parts I had lying around (wheels, brakes, new cables, cassette) and bought new bits and pieces (tyres, tubes, brake pads, rear derailleur, head set, front fork, chain).
I need to replace the chainset and the viable options are a Miranda 52/42 and a Shimano 50/34. I'm riding on the Antrim Coast Road which is fairly flat, and am fairly fit, even if I'm a little overweight.
Any advice?
(Save up and buy a new bike is what I expect to be told, but something more specific to the chainset is what I'm hoping for. Thanks guys.)

If I was visiting your area with a bike I would use the 50/34 as I see there are some steep climbs (Torr Head) that look interesting. No real advantage to the 52/42.

Depends what gears you're using in the freewheel but I agree that going for the larger size chainrings will not offer any benefit. What size are the crank arms?

If your plan is to enter more demanding sportives, a compact crankset will be your friend when you approach climbs later in the ride.

Crank arms are 170mm. For no reason other than that seems fairly standard/the size I'm replacing. Happy to take advice.

Since whatever cassette you end up with will probably have an 11 on it, you're highly unlikely to need a ring bigger than a 50. The only reason to go with the 42/52 would be to remove the outer ring and set it up as a 1x.
