Initially bought a 2009 Large.
Broke it at the seat tube/top tube weld after 6 months. Propogated rearwards from weld through seat tube.
Sizing wise: had to swap the 350 seat post for a 400 (6'2", 34" inside leg).
2009 was a bad year. 2010 introduced changes
Warranty replaced with a 2010 XL.
Much better build quality. All previous issues fully addressed.
Better sizing for me.
Excellent bikes on fast downhill stuff but not so great on the ups as the seat angle puts you a long way back. I had to run my seat all the way forward on the rails to get a better climbing position.
Stock bars/stem were hopelessly narrow/long. Swapped for a 50mm stem and 745 bars, which transformed the bike into something quite capable on steeper downs.
Rear suspension is very, very good IMHO. Never felt it bottom out despite running about 30% sag and some clumbsy landings to flat from up to 6' drops.
Back end feels flexy though and really benefitted from upgrading QR to bolt-through.
By way of comparison: I've since bought a 20" 2011 Orange Five, which feels smaller and more manouverable, better on techy stuff and climbs better too without being any inferior on the fast descents. The rear sus on the Five does not feel as good as the Meta's though IMHO and I'm frequently using all the travel despite running less sag than I would on the Meta.
I do like the Meta 5 but would suggest it needs a few mods to get the most out of it:
1. Shorter stem and wider bars
2. Double and bash
3. Chain device (stinger)
4. Bolt-through rear axle
Just an opinion. Hope that it helps.
