I’ve got a mk2 solaris, only one set of bottle cage mounts, and the height up the downtube is annoying, interferes with frame bag. Most dropper posts should surely allow for a low down boss on the seat tube, though some people still slam a normal post I guess.
I’m using my solaris for xc, not ‘trail’ riding, but I think the time may have come for them to do two 29ers, one xc/bikepacking machine for 100mm forks, lots of bosses and mounts and possibly a bit lighter, and a 120-140mm trail machine. I’d say it’s compromised at both at the moment.
