Crank arm shape is new compared to the majority of available options. The DS crank-spindle interface looks to have remained the same though, unlike the x-trecento which requires a proprietary tool. The NDS is new, almost looks like it could be removable? Nice to see stiffness wasn't compromised either, after moving to a 24mm spindle. I might be in the process of finding out I need a narrower q-factor than I always thought, so I'm also a bit apprehensive about that.

Are you sure an aluminium dub spindle even gets any lighter than a proper, non-waisted, 24mm spindle? Both weight basically the same on the Elilee X310. Every case of the ti spindle weighting more that can I remember was with a waisted spindle.

innormal is DUB lighter,this model just ti spindle ,make it lighter

I have a set of wheels from DFS and am very happy with the quality for the price. Zero regrets, and while it's hard to compare since my branded wheels are all older, I did not see a gap in quality between what I got from DFS and those older wheels.

I bought from them because I wanted a lighter wheelset with steel spokes, and they had some hub options that were only available through them.

The tariff situation makes it hard for US customers now, but seeing these weights really makes me wish I had waited for the lighter rims to come out.

have shipping way included tax and shipping time is fast
