Mixed love for the Swift here.
Mine in a 1x9 format was really quite heavy - nearly 30lbs but rode a lot lighter.
I guess a lot is down to build.
I also found even using a flat bar and o degree stem that the bar height was higher than I would have liked.
Average_Mark's Swift is circa 23lb IIRC and goes like stink but thats with an uber light carbon fork etc
Sam @ Singular had a few ex demo/shop stock bikes at good knock down prices recently.
Edit >>> Just read an email from Cotic to say they wont be making a small 29er due to rider/bike compatibility issues:
I know lots of you are interested in the Solaris frame, so here's the update. It tooks some doing to get comfortable on the bike as I like low-ish bars, but the Sunline 762's I got from One Industries Europe have been spot on, especially since I chopped them down to my usual 710mm width. Even though the Solaris has short top tubes as 29ers go, the 29er layout does make it hard to get bars low if you like that, so we'll be recommending flat bars mostly and sizing you guys up carefully to make sure it's spot on for you. It's also hardened my resolve not to do a small size. If I'm 6ft 3in and I found the bike felt too high with anything other than flat bars on it, then there's no way small size people are going to get anything out of a 29er in my opinion, or certainly nothing apart from something that rolls quick but you can't throw around, and where's the fun in that? A bike you can't chuck around certainly is not a very Cotic bike, that's for sure. We'll be doing medium for people down to around 5ft 9in, and there will be an XL size inserted above our usual large for guys up to around 6ft 7in ish.
