I just bought one of these today, $995, couldn't pass that up. Seems like a reasonable deal for frame only, a steal for complete bike. The combi uses the same rear end and linkage as the Meta 4X, which goes for $1400 frame only.
The shop guys took the fork, cranks, bb, f der and shifter back towards a 130mm Fox 32 float RLC. I robbed my XC singlespeed which I never ride of it's choice bits. Set up like this:
08 Commencal Combi S, size L, rockshox bar 2.1
08 Fox 32 Float RLC.
Protapers, AC stem, king headset.
Hone cranks, RF 34t ring, LG-1 guide w/taco, wellgo MG-52 pedals.
Avid Juicy 3's, 6" rotors.
X5 shifter, X7 der, sram chain, boat anchor SRAM cogs.
boat anchor SDG seat and chingchong commencal post and qr.
Front wheel: 32h Rhyno Lite, handbuilt DT 14g, specialized skraxle hub
Stock rear wheel: Commencal chingchong rim, crap white spokes, deore hub.
2.35" kevlar Larsen TTs, f&r with light tubes.
Weighed in at 31 lbs. I think it can get under 30 pretty easily. It has tankish seat, post, stem rear wheel and cogs. Thomson stem, post, dkg clamp, and XT cogs are going on order, and I'm putting a light FSA road seat on. I'm going to keep my eyes open for a used float RL or RLC. I am extremely tempted to order hope hubs and Syncros DP25 rims, but I think I'll hold off on that for awhile.
I guess that didn't really answer your question. But it builds up light. I can't imagine the frame weight is too different than the Meta 4X. 4X has the adjustable headtube, which adds weight, but a more compact front triangle, which should be a wash.
