Cotics look great in the flesh, Lurchers less so, plus they have steep head angles + PITA bb’s.
Ridden a Yeti Big Top around trail centres, Trans Cambrian, 24 + 12 hr races + its been uniformly great. Fast light, capable, stiff enough. Medium is bob on for me at not quite 6′ (70mm stem 720mm flat bars + layback seatpost for long rides). SC highball is shorter so might be a better fit? Med Solaris would be a good fit, no?
From experience (DOH!) I’d say an OK bike that fits well is better than an ace bike that doesn’t quite.
