48/32 or 46/30 chainrings for road crankset

[plopplop]

Hey, does anyone know where to get 46/30 or 48/32 chainrings for road cranksets? For fitting on 110x4 BCD cranks, like Shimano R7000 or R7100 cranksets. Or other cranksets that are on 24mm spindles.

The lowest 110x4 BCD I've seen are Stone chainrings which go down to 46/32t or 48/33t. You can find both older symmetric or asymmetric chainrings here:

For direct mount, they have this new style chainring that does 46/30t and  48/32t:

My personal preference is the Senicx 46/30t direct mount chainring. Chain line is perfect with no need for BB spacers which seem to be an issue with other AliEx chainrings:

Do you have a gravel frame? I bought 46/30 for my road frame and the front are not low enough to shift the chainring.

Yeah, on my TFSA frame I had to lower the FD all the way down with the 46/30 and it is not ideal. I would not go this way again...
I also like the Senicx stuff, so you could get a crank+chainrings for about 70 USD

I used a bikinGreen adapter to lower my FD for the Senicx 46/30T chainrings. Worked great. On some frames the chainstay would limit how much you can lower the FD, in particular smaller sized frames. I used it on a size small 52cm frame, and there was enough clearance to get it low enough for good shifting. But the adapter may not work so well on a size XXS frame, say.

Here's the listing I bought from: https://www.ebay.com.au/itm/155224761356

This is why I think eliminating round seat post tubes from gravel frames is a bad idea, since you loose the ability to use an adjustable FD clamp hanger. I think lower 2x gear options are much more efficient when it comes to climbing and loaded bike packing. Running big cassettes just look dumb on a gravel bike, add unnecessary weight and you get wonky chain lines. My 46:30/11-36t gravel frame can still sprint fast on the flats and climb the steep single track trails in my area.

After a few years with an XX1 Eagle cassette, on my gravel and many other happy builds, I'm not sure I agree with that

I think the problem is my location! It's all urban flats, with the only off-road being steep mountain climbing. My ideal climbing gears would be anywhere between a 40-44t big and a 24-28t small. I prefer not to increase my cassette size to keep the gear ratios a bit tighter and have a more road-like shifting experience. I tried 1x and it just blows when I want to haul ass on the roads.
