Works for me. Doesn't do straightpull spokes, but who in their right mind hand builds with those.

I have ridden also about a year and one bike packing trip to Norway. Had some serious speed wobble with pannier bags, fork mounts and bar bag. Since then I have made a rear rack mounting axle that goes thru the thru axle and made a stiffer upper rack attachment. Not tested yet. But this was the first time ever I had speed wobble. The frame is quite flexible.

Wise words there.

Bought from their website. Obviously complained, but I'm not holding my breath for any reply.
Compared to promised sending/shipping time, it took almost 3 times as long to get it.
So not great all together.

Well isn't this actual color a bit of let down.
