Rumour is (well, what I've read on a few websites) that now the new regular Lux is out, the new LT will be soon too. Probably only an update to the rear triangle though (since they're shared), so maybe no XS even then?
I found positioning to be a bit tricky on the LT when I got it. I tried the saddle where I thought it should go, for the same reach as on the Spectral, but it never felt right. So I tried much further back, and that actually feels fine, even with the long reach. Can't tell you why
Riding the Spectral feels really upright now though.
