I have a 120/120 travel Carbonda Cfm-909 I built last year that I like. Great climbing and great descending only complainant is a little flat ground peddle bob and that might just be the rider. Its a long frame so your trading a bit of agility for stability. The ican xc S5 looks to be the same mold as the 909 but since its heaver its a different layup. One person in the 909 thread had issues with his ican frame. Does it have a 120mm rear travel option? My large frame CFM909 was 2078g including the shipping suspension lockout so ican might be closer to 200g more now that Carbonda has increased the weight.   

Can you please support which damper bushing do i need?

Especially the width for dox damper
Is it exactly 30mm, or little bit more or less

Thanks

Exactly 30mm. I used a 30x8mm standard bushing, not offset, from offset bushings.
