Hi, I work for Ibis. I don't have a weight for an XL, but a size large NX build with DVO air suspension , 2.5" Assegai EXO + tires and sealant, weighs 32.5 lbs without pedals. With pedals, it sits around 33.5 lbs. That's on par with some carbon fiber bikes in the same category.
You'd have to throw on DD tires and a coil shock to push the weight upto 35-36 lbs.
The Ripmo and Ripmo AF kits we currently offer are identical, right down to the suspension. The only difference is that our highest price AF build kit is GX. We don't offer an AF with XT or XX1. We just haven't had any demand for those higher price points on aluminum.
