GT Zaskar FS Comp 29 — A Legendary Trail Hardtail Goes Full Suspension

The GT Zaskar FS Comp 29 in Indigo is the full-suspension evolution of one of mountain biking's most storied nameplates. GT took the iconic Zaskar name — long synonymous with aluminum trail excellence — and gave it a modern full-suspension platform that means business on today's aggressive trail networks.

Equipped with capable suspension front and rear, the Zaskar FS Comp rolls on big 29-inch wheels and arrives ready to tackle everything from flowing singletrack to chunky rock gardens. It is a bike that wants to be ridden with conviction.

Wide, grippy tires underscore the bike's trail-focused attitude. The Zaskar FS Comp improves as the gradients steepen and the speeds increase — it rewards riders who commit fully to the descent.

The rear suspension works superbly at absorbing trail chatter and smoothing out rough impacts, while the front fork handles heavy hits with confidence, allowing you to stay focused on picking lines rather than worrying about the terrain beneath you.

It may not shatter any uphill speed records, but with mountains of traction on tap, you will have no reason to put a foot down and walk on technical climbs.

Clean cable routing and purposeful frame details throughout the Zaskar FS.

GT constructed the Zaskar FS Comp 29 around a 6061 aluminum alloy frame that blends stiffness with trail compliance. The frame incorporates ISCG05 chain guide mounts, a threaded bottom bracket shell, and a subtly hydroformed down tube paired with a shaped seat tube for a clean, modern look.

Reinforced welds and gussets at high-stress junctions add structural integrity, while the low-slung top tube keeps standover height manageable — essential when you need to bail off the saddle quickly on steep descents.

Internal cable routing enters through neatly finished ports on the down tube and exits through clamped grommets, keeping everything tidy, rattle-free, and easy to maintain.

Suspension Design

The suspension linkage keeps things efficient and responsive across varied terrain.

GT employs its proven suspension platform on the Zaskar FS, using a linkage-driven design with a pivot located on the seatstays and a rocker arm driving the rear shock. This layout is designed to balance pedaling efficiency with sensitivity to small bumps.

The rear travel is managed by a capable piggyback-style shock — the additional oil reservoir helps the shock maintain consistent damping performance during extended descents by dissipating heat more effectively.

GT claims the suspension platform offers excellent small-bump compliance along with a progressive feel on larger hits and drops. This progressive nature means the bike resists bottoming out harshly while still feeling supple over roots and rocks at moderate speeds.

GT is also one of the brands that provides detailed suspension setup guides, including recommended air pressures based on rider weight — a thoughtful addition that helps riders get the most out of their bike from the very first ride.

The Zaskar FS Comp embraces modern trail geometry with a long, low, and slack approach.

GT has not been conservative with the Zaskar FS Comp's geometry. The frame fully embraces the modern long-and-low philosophy, giving riders confidence at speed and stability in technical terrain.

A generous reach puts plenty of bike in front of the rider, while a relatively short seat tube keeps things compact for maneuverability. The head tube angle is relaxed for improved high-speed tracking, and the steep seat tube angle positions the rider efficiently for climbing.

The bottom bracket sits low to the axles of the 29-inch wheels for a planted center of gravity, and the chainstays are kept relatively compact to maintain agility and responsiveness in tight switchbacks.

Quality suspension components deliver confident control when the trail gets rowdy.

The fork provides both high and low-speed compression adjustment alongside rebound control, while the rear shock features rebound adjustment and a lockout lever for climbing efficiency.

The drivetrain comes from SRAM's GX mechanical groupset, paired with capable hydraulic disc brakes clamping on to generous rotors front and rear. Together, these deliver reliable stopping power and crisp shifting whether you are grinding uphill or letting gravity do the work.

A pair of aggressive, dual-compound tires are wrapped around sturdy rims in a wide profile that delivers ample grip in loose and mixed conditions. Their EXO-class casing strikes a balance between puncture resistance and suppleness.

The complete bike tips the scales at a competitive weight for its category, ensuring it is no heavier than the key competitors vying for trail bike honors this year.

The GT Zaskar FS Comp loves to fly — push it hard and it rewards you with grin-inducing confidence.

The suspension rarely needs more than a few clicks of adjustment beyond the recommended baseline settings. The dampers respond well to fine-tuning, and the fork's Charger damper technology is no exception — setup is quick and the results are immediately felt on the trail.

The manufacturer's setup chart proved an excellent starting point, with only minor tweaks required to match personal riding style. Adding a few clicks of low-speed compression to the fork helped match the rear shock's feel perfectly.

The Zaskar FS Comp may not be the perkiest climber, but it will haul you up anything you point it at.

At a competitive weight for its class, the Zaskar FS Comp sits comfortably alongside other trail bike contenders — it carries no real disadvantage heading uphill.

The tires are not the fastest-rolling option available, but their dual-compound construction ensures they move along efficiently enough while saving their real grip for where it matters most — in the rough stuff.

With a smooth pedaling cadence, the Zaskar FS Comp climbs as well as any of the best trail bikes in this test group. If you need maximum efficiency, the lockout switch on the shock is easy to reach.

The steep seat angle plants your weight nicely over the cranks, especially on gradual rolling climbs where it provides a comfortable, efficient position for long forest road grinds.

The piggyback shock sits neatly in the frame triangle, delivering consistent performance.

On technical climbs, the supple rear suspension generates excellent traction, enabling the tires to dig into loose dirt rather than skipping and sliding. Harsh edges from rocks and roots are smoothed out beautifully.

The rear hub has a wider engagement angle than some competitors, though. On very technical climbs where you might be ratcheting the pedals to clear obstacles, this can make the bike feel slightly less responsive.

When the bike dips into its suspension travel on steep pitches, it can shift the rider's weight slightly, affecting the overall sprinting feel — it does not feel quite as taut as some of the snappiest competitors in the category.

The SRAM GX drivetrain handles climbing duties admirably — shifting under load is smooth and reliable, feeling even more refined than some of the competition's offerings when conditions get muddy and gritty.

The steeper the trail, the wider the grin — rail-like cornering is a hallmark of this bike.

The Zaskar FS Comp absolutely shines when the trail points downhill. The steeper and rougher the terrain, the harder you push it, the better it gets.

That generous reach ensures there is plenty of bike in front of you, and with ample spacers under the stem, there is room to run the bars high for steep descents or slam them low for mellower blue trails.

The short chainstays help haul the front wheel around through tight switchbacks and rooty turns, or lift the front when you want to pop and play over trail features. Although absolute high-speed stability could benefit from slightly longer stays, the trade-off in agility is worth it for most trail riders.

Short chainstays help keep the rear planted and the handling lively through tight terrain.

The linkage-actuated suspension, combined with the quality rear shock, is beautifully smooth when rattling over root networks, keeping the rear wheel planted and your tires digging into the trail surface.

The rear end does stiffen slightly under braking, causing it to skip and hop over braking bumps at times. In the right circumstances, this just adds to the playful character of the bike as the rear wheel slips and slides through loose terrain.

When it is time to build speed over lumps and compressions on rolling terrain, the suspension support arrives a fraction later in its stroke. This means there is slightly more effort required than on the plushest trail bikes, but when gravity takes over, the Zaskar FS Comp is flat-out fast.

Aggressive tires deliver class-leading grip in every condition.

The piggyback rear shock performs beautifully in its high-spec configuration, with very little to criticize. The fork with its advanced damper technology is a high-quality match that complements the bike's trail manners perfectly.

Send the bike into a chute and it handles the compression without bottoming harshly, railing through the catch at the bottom. The damper also deals with high-frequency chatter from repeated small hits with impressive composure.

The ability to fine-tune both high and low-speed compression to match your riding style and trail conditions underscores the thoughtful spec choices — the engineers clearly know where to invest the budget for maximum trail impact.

The GX drivetrain delivers smooth, reliable shifting even in the worst conditions.

This is exemplified by the oversized rotors paired with the hydraulic disc brakes. These noticeably lift the braking performance from adequate to genuinely impressive — especially when conditions get wet and muddy.

The lever feel on the brakes can be a touch wooden with the stock organic pads, and they are not quite as sharp as sintered pad setups. However, the overall stopping power is more than sufficient for confident trail riding.

The tires may slip slightly on wet hardpack or heavy mud initially, but as soon as that clears, they are a class-leading all-terrain option — aggressive, grippy, and reliable in the dual-compound, EXO-cased configuration found here.
