thegreatape, apologies for delay replying (am away on riding holiday at the mo, so limited internet:))
According to the angle finder app on my phone, the headtube angle on the Atlas is about 68.7 degrees with the 140mm fork. The fork I’m running has a 51mm offset, which supposedly quickens the steering. Handling and ride wise, I guess it depends where and what you’re riding. For typical trail centre reds, I find the Atlas very good, as it feels like the best bits of a 26er and 29er combined in one bike. However, if you regularly ride loose rocky rubble filled natural trails, I’d look for something with a longer wheelbase and maybe a touch slacker – like the Tallboy LT! It’s not that the Atlas is terrible on that terrain, it’s just that it doesn’t feel as invincible as some other bikes.
Personally, I think the Superlight has the edge over the Atlas in natural terrain, as it does that single pivot thing of sitting back in its travel and slackening out a bit. The Atlas has very neutral suspension, and although I regularly ride mine down very steep tech trails, it needs more attention than the Superlight.
The suggestion of a Camber Evo is an interesting one – and if you can get them with a Pike, I think it could be a very good option. My OH got a carbon non-evo camber 29 as an insurance replacement, but she didn’t get on with the suspension on it (Fox Evo CTD rubbish). I rode the Camber quite a bit and liked it, but the Evo model seems to address the quirks on the non-Evo model. Only thing to be aware of with Specialized is that they fit cheap bearings in the suspension, and compared to decent single pivots or SC vpp2, they can be a real pain to service/replace bearings. (I’m sure some Spesh fans will correct me there though;))
