If it trail riding and not a race then no problems with 140-150 , they usuallly build up around 30-32lb depending on your pocket depth, I really enjoyed my Orange 5 for the last 2 years but recently changed to a SC Butcher and was amazed how much better it climbs and the suspension seems to be more refined, weighs 30.5lb with Float 36’s , Reverb , Flows , XT 1×10 and Hope Tech 4’s etc probably with a Float 32 and more bling you could get below 30lb.
[Well, it’s about the quality of the suspension as much as the travel. The overall weight of the bike.]
As Badlywireddog said this makes a difference, not ridden the Cube so would see what Stereo owners say and if possible try and ride one, although I didn’t on my Butcher just went with what I read and what people told me on forums , lots of faith in people. 😀
