A Fathom is going to be a huge upgrade and you will definitely start to feel more confident after a few rides. I have owned a few decent full suspension bikes from the early 2000’s and I must say the Fathom is very trust worthy (my current ride:2019 Fathom 1 27.5). The modern geometry makes a big difference. The lack of rear suspension is the only limit I have on it…but it’s an amazing bike at that price point. And it’s a blast to ride even in the rough stuff.
