Looking good with those blue bits. It will be interesting to here how does it ride with a 100mm forks. Bet the cornering is better than on your previous GT as the BB is significantly lower. Post a review here sooner than later!
Rides really good, it's basically the improvement in head angle, front center, and standover that I was looking for and it feels very natural. It's probably the smallest, most nimble feeling 20" frame I have ridden.
I agree, sizing is really compact. At first I was concerned about going 18" in my case but it proved to be a great choice. Glad you enjoy riding it and hope you are not regretting that extra weight.
