I had a 2016 27.5 that I freakin loved in terms of descending. The only reason I sold it was the horsey link was in a bad spot and the rear end extended a lot under hard pedal loads. Awesome for grinding up dirt roads because it helped with traction but it hung up a lot pedaling up chunk. It really was tiring on long bumpy singletrack climbs. They dropped the bb, and reduced the antisquat on the new ones. Personally I'd be stoked to have the 27.5 version based on how much I liked the previous one for high speed smashing.
If they really are going to do some high pivot elevated chain bullshit for a trail bike, that's even more reason to buy the current one.
Here is mine:
I just switched over from the sight. Let me know if you have any specific questions and I will try to answer them. I love it and it is about as straight forward as these bike get these days.
I have a medium with a 160mm fork, so my SA is 74.5 and I do not have a problem with it. The geometry and the whole cockpit feels great both up and down. One thing to note though, the Range has a totally different feel than the Sight. The Range is built to take a beating with a heavier carbon layup, and suspension that is supple and forgiving. The bike is as stiff as any dh bike I have owned and tracks like one, and for downhill, I think the suspension is great. It is soft off the top, supportive in the mid range, and quite progressive at the end. But you are going to feel suspension movement when climbing and pedaling for sure. I am loving it for Pisgah, where you flip the lever on the shock and climb long fire road or gravel climbs and then bomb down steep technical downhills. It does monster truck up technical climbs with great traction though, you just have to expect some give in the bike while doing so.
