I've got a santa cruz chameleon right now, with a rockshox revelation 426 fork (110-140mm travel), chris king 1+1/8 headset, XT BB, thomson 30.9 seatpost.
However, for certain reasons I'm not happy with the chameleon, and want to get a new frame. I would like to keep it as light as possible, while still being able to take 140mm of travel. I also want stiffness.
I have looked at the ragley mmbop, but what's it like with 110mm travel? And I think I know you can change a 1.5 headset down to 1+1/8, so my fork would be fine with the mmbop, but would I need a new headset? Could I use a 1.5 chris king headset?
And what other frames could you recommend, something under 5-6lbs?
