The M.1 GX Eagle checks all the boxes: lightweight carbon frame, 1x12 GX Eagle drivetrain, 120mm SID suspension fork, Stan’s S1 Team wheels, and quality components from FSA and Fizik. This is a fantastic entry bike for the student-athlete. You could spend more to ride fast, but honestly, you don’t have to.

It's like a high end AK

I have taken very little care of this bike and it keeps performing. I purchased this on black friday 2019 and feel that I can give a decent review. It has treated me well for several hundred miles, with infrequent chain and frame cleaning and checking the air. That's the only maintenance I have done. I went tubeless, changed the pedals, and grips. I went to Bentonville and the carbon fiber hardtail was a dream to pedal up and down the numerous hills and to see my friends that has full suspension and aluminum frame struggle. I have gotten some crazy top speeds in the open and it's nimble in the narrows. It's out performed all expectations.

NICA Race bike

Son loves his Viathon. 8th out of 72 first race of season.

Great so far

I purchased the M.1 GX Eagle on the Black Friday special. It is an amazing price for the quality of MTB frame and components. The bike arrived safely with very protective packaging. Assembly was straightforward. I was out on the trail in less than 1 hour. My only recommendation would be to put more info on bike sizing on the website. For those not familiar with MTB geometry, it can be hard to map your physical size (inseam or height) to the appropriate bike size. Looking forward to many years of great use with this bike.

New Hot Rod

I am super stoked to be on a new Viathon M1. The quality of the frame finish is excellent and I can't wait to log more hours but I am super impressed with the entire package.

Fast and Fun - downhill gravel bike?

My other bike is an Evil Following and I wanted something different. This carbon hardtail frame with GX eagle and 120 mm fork seemed to fit the bill. I have been impressed with how smooth the bike feels, the rear triangle design with carbon definitely eats up the bumps. (Looks like a similar design to the specialized epic hard tail) I would call this my version of a gravel bike. Much more capable but also fast uphill or on flat trails and pavement. Adding a dropper post is the key to making it even more capable on the downhills. May be the most efficient mountain bike I have ridden, gets up to speed fast and feels great.
