I just got back from a Giant demo day. Did a bunch of miles on a
Reignand a
Trance advanced, both 27.5.
Reign: Definitely a killer bike but the geometry is not for me. The Pike fork is fucking awesome though, but even after switching sizes and having the techs do more adjustments than I really felt comfortable asking for at a demo day, I couldn't get the thing setup so that I wasn't leaning on my wrists the whole time. It descends awesome (a $6000 bike with 160mm of travel should) but it felt really twitchy on singletrack and I just couldn't get used to it.
Trance: Sweet fuck what an absolutely incredible bike. This was the LBS owner's (friend of mine) and was setup with the best of the best everything - XX1 groupset and all. I did a bunch of miles on a small, and by all specs I should be a medium, but there's more than just frame size that goes into a good fit (Seat tube height, etc) and the small felt perfect. The one I was on was probably between 8-9k, and just bad-fucking-ass. Descending, singletrack, tech stuff, everywhere. The only downside is that I got 13 Strava PRs on a place I ride a ton on a bike that I'll never be able to afford, but it certainly was a blast to flog the thing for an hour. The best upside is that he left his GPS on the bike when he handed it over to me, so I ran his and mine at the same time and ended up getting him a bunch of Strava PRs, so I'm faster than the LBS owner on his own bike, haha.
I rode a couple of other things that were less interesting but that's the basic jist of the two I spent the most time on. Demo days are a blast - definitely go to as many as you can, even if you aren't shopping around. Met some cool people, talked a bunch of shop and all in all just a super cool way to spend an evening.
Here are the steeds in question (pardon my usual hipstergram). Green is the Reign, black is the Trance.
