Review: Giant Anthem X1


“Climb efficiently and descend like a champ.” That was the line from a Giant Bicycle sales rep when describing the theme of the company’s Anthem line of mountain bikes.

For the past few months, including three competitive events and hundreds of collective miles on training rides, I have put Giant’s Anthem X1 model to a thorough test. The X1, the second-in-line bike in the Anthem series, retails for a pricey $3,700. But it is a killer ride overall. Like the rep promised, it has proven to ride admirably across a huge range of conditions and terrain types — up and down the mountain.

One example: I rode the X1 almost 200 miles this winter in an adventure race in Chile. My team was racing primarily on rolling gravel roads and bumpy double-track trail pushing hard to make time. In that race setting, the X1 was super speedy and efficient. It was comfortable after hours of riding on end.

In more traditional mountain-bike settings, the X1 handled singletrack and small stunts with ease. It has an aluminum frame, and the total bike weight is about 24 pounds. There are Shimano XT and XTR drivetrain parts. Suspension — 100mm on the fork and frame — comes from a Fox 32 F120R fork and a Fox RP23 rear shock.

On hard training rides near home, I have seen few shortcomings with the bike. It is fast, fun, and efficient even with its healthy suspension system. There is little or no bounce when you pedal on the flats or going uphill.

I do have two minor gripes. The handlebar width is a bit too wide for my taste. I added grips from Ergon, and the bar now measures 28 inches wide. This makes trails with tight trees sketchy at points.

My bike came stock with Michelin’s Dry2 Expert tires. These tires are mediocre at best. I plan to replace them soon, and apparently Giant ( was not super enthralled either. The new model Anthem X1 bike this spring comes stock with Maxxis Crossmark tires instead.

Overall, I am happy with the X1. Its speed for racing — and for fun! — is its No. 1 asset. Add its adequate suspension, lightweight build, solid parts, and comfortable design, and the X1 is one of my favorite bikes tested this past year.

Do I now “climb efficiently and descend like a champ” as the sales rep promised? I hope so. This speedy bike, at the least, makes me feel that way.

I generally cut a little material from the ends of my bars. Manufacturers send them really wide for some reason -?

Given the mediocre tires, solid parts, (not a full XTR group if I understand you correctly), an aluminum frame and average suspension components, the price tag would seem like a stretch. I would expect a price point perhaps $700 – $1000 less. Otherwise the bike looks like a nice XC machine.

It can be $1000 or so less online. The $3700 price tag is MSRP, which is often higher than the price people pay, especially after a product has been available for a couple months.

I have the Anthem X0, and it is a phenomenal improvement over my Giant NRS2 which was for years one of the best suspension systems on the market. Climbing with the Anthem is balanced so much better. My front wheel rarely comes off the ground and the only time feel a need to stand up is when my but gets sore. I used the Anthem for Primal Quest last year, and it had no mechanical problems, even after being caked in mud, multiple times, so bad that the wheels would not turn, completely submerged in a lake to get the mud off, and re-lubed with chainsaw oil. I don’t consider myself a super technical downhill rider but the stiffness of the wheels and frame does seem to improve control. It will be a long time before I get another bike.

“comes from a Fox 32 F120R fork and a Fox RP23 rear shock.”

The F120 Fork is a 120mm travel fork. I believe the Anthem actually comes with a F100
