Got out to a sweet demo day today and tried out a bunch of bikes on the same nice technical trail.
The highlight was the Yeti SB5. For the types of trails we've got up here - twisty, rooty, chutey - there was no better bike. Tracked extremely well through technical decents, but still climbed like a billy goat. ~2-3 lbs lighter than equivalent offerings from Santa Cruz and Pivot. By far the best suspension performance, very responsive feel, but ate up the little bumps that would slow down the other bikes I tried.
Second was the Santa Cruz 5010 2.0. I liked this bike a lot too, but the Yeti seemed to just edge it out in most categories for me. I felt that the suspension got caught up a bit more on roots, rocks and ledges, sapping just that little extra bit of momentum. Climbed and descended well, but didn't track as well through rougher terrain than the SB5. I would consider this bike if I could get a comparable build for a noticeably lower price than the Yeti
The biggest disappointment was the Bronson 2.0. Pedalled heavier than it felt to lift, wallowed through turns and didn't climb all that great compared to the other bikes I rode. Felt piggish through turns, like you'd have to almost push is sliding through the twists of the trail. I think it would be great if you were a more gravity oriented rider, but it didn't seem like a great bike for most of our trails. Could be great for Mt. Ste. Anne or something where there's really steep aggressive rocky and rooty decants with a shuttle back up to the top. Rode much closer to what I would have expected the Nomad to feel like.
The Pivot 429 felt like not quite enough bike for the way I ride, and I preferred the 27.5 wheel size in practice. That said, it did exceed my (admittedly somewhat low) expectations.
I wanted to try the Hightower but they only had one and it couldn't be taken out on the trails, so I didn't get to give it a fair shot. My LBS is insistent that I should try it before making a purchase, so I'm going to try to give it a shot sometime in the next couple of weeks.
I left the event feeling pretty confident that the SB5 would be my next bike.
