I got the 27.5" version of this bike, which is definitely the way to go. It is a lot easier to find 700c wheels with a 12mm through axle than it is for a 27.5". Out of the box the bike is very clean looking and most of the parts are well though out.
On the dirt the 27.5" tires did a great job soaking up the bumps compared to a 700c tires due to the increase in volume. They really shine on brake bumps to reduce the jarring feeling you usually get. Being able to switch between the two wheel sizes adds a great amount of versatility. Can handle dirt roads to single track.
The few misses are minor but should not be overlooked. First one is the water bottle cage mount placement. This is for the 61cm frame so I can't attest to it being like this on the other sizes. The seat tube cage sits low, which I can understand to make room for a frame bag but it sits so low that the bottle actually hits the down tube when placed in the cage. The down tube cage sits low enough on the down tube that the bottle rests on the down tube water bottle. Probably could be fixed with different water bottles that offer an adjustment but a few millimeters can make a world of difference.
The other small issue is that the Enve fork, which is great, comes only in post mount but the frame is the newer flat mount. Not a big issue with a complete bike but if you were ever to upgrade it can make things a little difficult.
If you have any questions about the bike or the fit please feel free to reach out to me and I will be more than happy to help you out.
