112 links enough for a 11-28 52-34 chainset?

If I'm not mistaken most chains nowadays are sold with 114 or 116 links. Just get the length, and remove links as necessary.

For what it's worth, my drivetrain is a Shimano 105 RD-5700-GS medium-cage rear mech working on a 12-30T cassette and 50/34T chainrings. Chainstays are 430 mm long. 114 links works perfectly.

I have another bike with slightly shorter chainstays but almost the exact same drivetrain components, and that uses 112 links worth of chain.

I ran 52-34 for a few months in 2014 until I managed to get a 53/39 chainset through the classifieds here. 

I ran it with a Tiagra 10sp front mech, ultegra 10 speed rear medium cage and, I believe, 11-28 on the back. Ultegra chain if it's worth mentioning as well as 105 5700 shifters  

It ran absolutely perfectly. I did change on the front with a slightly more gentle touch but I didn't drop a chain or do any damage. 

Think it will be a 52-36 chain set also unless you've changed the rings, cos an 18 tooth gap will be pushing what a front derailleur is capable of. The biggest gap is normally 16t, so 50-34, 52-36 or less with the likes of 52-39 etf

Most, if not all, new chains are 112links as standard so if anything you'll be shortening it by a few links.

It will depend on the length of your chainstays also but I've never even worried about how many links a new chain comes with and not once had a chain too short in 20 years and 40 or 50 bikes worth of assembling/disassembling and maintenance.

Any chain from a reputable brand will be fine!
