My Gravel bike (Fugio) came with a 42t Apex chainset. I would like to drop it down to 38t.

My google research tells me that Sram made the apex so that no other chainring will fit. Nice one.

I am now struglling to find an altenative 1x chainset that comes with a 38t option. Any ideas?

The sram MTB ones do IIRC. Or any crank that takes a direct mount chainring

Basically any sram chainset with a 5 atm 110bcd spider - so all of them except for that daft proprietary 4 arm apex one. Rival/force/red, the “normal” road double and 1x versions are the same. Best thing is probably to get a cheap or second hand road one (often less than the 1x version for no reason) and then flog the chainrings & buy a 1x 38t ring.

Eg:

Or just ditch sram and get a shimano road crankset and an aftermarket 1x ring.

Hadn't realised that, good to know! 1x position = inside position on the double I assume?

OP, I've got the same Apex cranks, so feel your pain! (Have you seen the price of replacement rings for them?!??) I was able to change the cassette to something with a larger big sprocket, but I assume you'll already have a big cassette on the go

@mashr not sure about non-sram chainrings but their own x-sync ones are offset so you mount them where the big ring would be and the chainline sorts itself
