Mountain goat

The Good:

Climbs great, suspension feels bottomless, 2x11 drivetrain still rocks.

The Bad:

Not the best saddle on the bike.

Overall Review:

So I bought this bike at a trek superstore on sale. This is the first trek I have owned and I’m happy with the purchase. It climbs really good and descends better. The suspension is great and the weight for my bike is at 27lbs for the 17.5 29er. I have to say this is my favorite bike so far. It does everything I need it to from an occasional XC race to long trail rides. 

Previous owned- Specialized Epic 29expert evo, Scott Spark 29, Santa Cruz Nomad, Specialized Stumpjumper expert 29er.
