Giant Anthem X 29’er 1 Review - BikeRadar

Giant effectively rewrote the rule book for 100mm full-suspension bikes with the original Anthem X, which was blisteringly quick but also huge fun. Now they’re trying to do the same with 29in wheels. 

The Anthem X 29'er's low weight and race-bred handling won’t be for everyone, and there’s no doubt that the Giant asks more of its rider than some of the slightly more easy-going competition. If you’re prepared to put in the effort, though, it’ll pay you back in spades. It should be top of your list if racing to win is what your riding is all about.

Ride & handling: Low weight, great handling and superbly balanced suspension

There’s one thing that immediately makes the Anthem X 29’er stand out next to its immediate competition, and that’s weight. Or rather, the lack of it. At a hair over 12kg and under the magic 27lb barrier, the Giant certainly isn’t carrying any excess baggage. Compared with lardier rivals, it positively bounds up the hills. 

The 2x10 transmission lacks the lowest gears of the 3x9 and 3x10 competition but in most trail situations the lower weight makes up for the lack of a wall-climbing ratio. Like its 26in-wheeled counterpart, this is a bike that wants to be ridden fast. Weight aside, a big component in this bike’s ability to chew trails up and spit them out whole is the rear suspension. 

It’s been around for a while but Giant’s Maestro platform remains one of the neatest-looking and best riding platforms out there, delivering – in this case – up to 100mm of rear wheel travel with no fuss, no drama and precious little indication that there’s anything going on at all. Except, of course, that the trail’s disappearing rapidly behind you. 

The fork is a good match for the rear end and the 15mm axle’s extra torsional rigidity, though subtle, noticeably improves the Anthem X 29’er’s ability to go exactly where you point it. If there’s a downside to all this low weight, pedal-to-the-metal exuberance, it’s a slight tendency for skittishness on everything from low speed, technical climbs to flat-out, rock-spitting descents. 

With an alert rider on board, though, the Giant’s capable of ironing out even the trickiest of obstacles – we cleared a nasty rock garden that’s eluded us for months for the first time on the Anthem X 29’er. As recommendations go, that’s not a bad one.

Frame & equipment: Well sorted, mature suspension setup

Giant’s Maestro platform underpins their entire full-suspension line-up, from cross-country racer to gravity-fuelled freeride sled. The one-piece rear swingarm pivots from a linkage running between the lower shock mount (in the case of the Anthem X 29’er), over the bottom bracket to a mounting point at the front of the chainstays. The shock, meanwhile, is activated by a rocker arm. This creates a floating pivot point. It’s simple, reliable and effective.

The Anthem X 29'er's chunky, square-section down tube and tapered head tube form an efficiently rigid backbone from which to hang everything else, but the rest of the chassis – and particularly the slender, brace-less top tube – is conspicuously and rather elegantly svelte. For a bike that’s more likely to be ridden fast cross-country than launched off the nearest cliff, it’s an approach that makes perfect sense.

The 2x10 SRAM transmission probably helps in a small way, too. It’s a particularly nice setup, with crisp shifts and reduced duplication of ratios (compared to a standard 3x10 drivetrain). Avid’s Elixir 5 discs bring everything back to a halt. The Maxxis tyres fitted to our test bike were the wrong ones – you’ll find Anthem X 29’ers sporting Schwalbe Racing Ralphs in the shops.

The deep section rims on Giant’s 29er wheels help to reduce spoke length and increase wheel stiffness – a good thing on big diameter hoops that are going to be subjected to off-road torture. But those deep sections don’t always mesh well with standard length inner tube valves, leaving too little to clamp a pump around. Make sure you stock up on long-valved tubes for spares…

A Fox RP2 shock and F29 fork give a pleasingly integrated feel to the front and rear bounce, with a 15mm through-axle up front helping to stiffen up steering responses. Our only niggle is the grips. They’re cheap and squidgy-feeling, and look out of place on a bike costing the best part of £2.5k.
