Good bike

Just got the bike a couple of days ago from a shop, went on the trail the next day. I'm the type of guy who loves doing really techy trails with jumps and all that stuff. Me and my buddy went on this parks jump-line and the bike handled AMAZINGLY. The only thing that I didn't really like was that the suspension was really stiff, so some of the landing were a bit hard, I also had the preset really low. So maybe it was a user issue with me, or maybe it was the bike. Other than that, this is the best MTB i've ridden.

Great bike

Absolutely great bike. Although I wish they didn't cheap out on some of the main components like pedals, grips, and seat. Other than that the brakes are great, very nice parts on this bike. The MicroSHIFT system is okay. I wish it would shift a little smoother. The fork is very nice, and overall the bike feels great and you get very comfortable on it quick. Also looks great.

I use this as my

I use this as my gravel bike as I don't mountain bike that much. It's perfect for that. But I think would be a good mountain bike maybe more for beginners or not too high tech trails as there is only suspension on the front. The price was very good too.
