I have a 2014 Zesty 527, the only real difference is mine is carbon and the 427 isnt.
It’s great, really good.
As a comparison with similar types of bike I’ve had in the past an Intense 6.6, Pivot mach 5, Ibis Mojo and in my opinion is better than all of them. A much more capable all rounder.
I dont clip my heels (size 10 feet), or anywhere near to be honest. I’ve been noticably faster on technical trails that I know well.
I’ve been riding my hadtail 29er a lot lately and I was worried that the zesty would take out the fun and feel of riding fast, but I was wrong, it is a complete hoot.
I epected it do descent very well (which it does), but it also goes uphill with surprising ease.
I’ve changed mine from 2×10 to 1×10.
