Thanks for all the insights and the link to that thread. I work for Santana so I'll definitely be using a Beyond, maybe stock, maybe custom with some grams shaved (who needs a disc mount, rack eyelets, 17" chainstays, and 4 waterbottle mounts?) At first I'm gonna build it up with a nearly standard Santana parts kit only substituting lighter brakes, saddles, a special pair of Spinergies, and pedals. Then I'll do stage 2 and stage 3 builds to see how light it can go and Lightning cranks will probably be a part of that as I've used them for several years. We made the call today to use Dura-ace instead of the lighter Red because Santana has always specced Shimano. I now realize that the "complete bike weights" I saw from Paketa and Co-Motion were without pedals so yeah, getting under 22 is gonna be hard. However, I've built 11lb roadbikes, 26lb enduro bikes, and 30lb DH bikes so I'm up for the challenge. I'll keep you guys posted.
