I still prefer 2x chainrings for my gravel bike. However 50/34 is too big for me with almost half of the cassette left unused with big ring.

Then I found Gearloop 44/28 chainrings and I went for it.
Gearoop 44/28 direct mount chainring weight about 130g, cost around $140.
I pair it with Quarq Dub crank arms, weight 339g with some unnecessary plastics. This crank arms cost me $196.
Together, this tiny compact crankset weight under 476g without unnecessary plastic pieces. Using 28t front ring together with 11-30 cassette in the back, I now have sub 1-1 gearing, while also having relatively tight jump between the gears. It shift pretty nice too, although I need to shift a lot of gear in the back to compensate for the big difference between big ring and small ring (still 16t difference but ratio wise it is more than regular compact).

On scale:

Initial installation, with front derailleur set way too high for 44t chainring.:

I have to move the blaze-on mounting tab a bit lower to mount my FD low enough for proper installation. To be honest, it shift the same as when the FD is way too high. I guess by moving it down, I just reduce the chance of overshifting and drop the chain on the outside.

Can you provide a link where you can get it? All i see is direct mount, but not 8 bolt direct mount that the Quarq DUB D1 crank arms use

Thanks

That is awesome! I wish they would also make one for the DUB Power meter spider 107bcd

DM subcompact 2x rings. it's about time.


As discussed in other threads sram has downgraded the quarq arms from what you have (i think the same as the red offering) to basically the force offering.

How's the shift quality? Able to shift under load at all? Hard to tell with the black ano and the lighting in the photos - but looks like no shift ramps at all

Yes. The shift quality is actually quite good. The benefit of direct mount chainring is that they can align the big and small ring to be absolutely right.
What annoys me is the ratio change between the ring though. 44 to 28 and vice versa is a big big change in gear ratio. I need a lot of compensation rear shift.

That seems like a positive to me! I want a bigger gap in front and closer ratios in back, with a large overall range. More rear shifts to compensate is fine with me
