Spectral now available with 125mm travel, but same geo as the bigger version

125/140 is a pretty good spot for a lot of the trails I ride, but that's a damn slack HA and relativity long chainstays for what should be a 'trail' bike. The tight squeeze for the water bottle would suck too.
With it not being much lighter, or really different overall, I'm not quite sure why you wouldn't just go the 150mm version. Yeah it might make your local laps a bit too tame sometimes, but it's also a bit more forgiving if you want to push things.
