Experience going from 1x to 2x on gravel bike?

Especially for light weight issues concerning cyclocross / touring bikes & parts.

You can add rings to the existing crank can’t you? Easton should have at least 46/30 and 47/32 available as rings to swap. I have 46/30 + 11-42 and find it to be nice for mixed use non competitive rides in the South Bay. The big ring works for road use and the small ring is good for trails.
I have and enjoy the Easton 46/30 (with a 11-32 cassette), but, again, the OP would have to sell the Hakka to use that crankset because the Hakka does not support 30 (or 32) rings. Indeed, that's exactly what I experienced ... I had to disassemble an almost completed Hakka and sell the frame at a big loss because I had purchased the Easton crankset and wanted to use it. Sigh, but it ended well as I replaced the Ibis with an Aspero.

Might be able to get a longer spindle for the Easton and add some spacers. Would widen the Q, which may be another issue, but I *think* the Race Face branded spindles are available longer than what comes with the Easton. I was contemplating getting a Cinch PM for the Easton that came with my Aspero, only reason I thought of this. That being said, I also thought the Easton 47/32 uses the same chainline as a normal road compact. Are you sure it wouldn't work?

I'll leave it up to you to figure out the other 30%. If you are in any way offended, that's on you.

I assume that means smaller than a 30t won't work?

Because of dropped seatstays, the Hakka MX doesn't accept less than 34 teeth in 2x and in for the same reason, the Open Up(per) doesn't even accept less than 36.

It's one of the limit of this design ...

Not sure about the Open UP on this....I e-mailed the company asking whether the Easton 46-30 would work and Andy Kessler wrote back personally and said it would :thumbup: I also seem to recall some low-tooth cranks on their user gallery. The WIDE, in contrast, is pure 1x only.

Not sure either, just read it on their website :wink:

This is not true about the Open U.P.(P.E.R.) frames. They will take 34 or 33 in bcd depending on the setup, and 30-32 in direct mount.

Their site, which you refer to, lists max size, not minimum.

Do you need tightly spaced gearing? If not, get an e13 9-46 cassette and a slightly smaller chainring.

The Sram 1x derailleurs with shift it just fine. 34-46 is a decent climbing gear, and I can spin 34-9 to 50+ kph.
