X-Lab AD-9 and RS-7: Two Road Bikes Worth a Closer Look at Very Different Prices

Introduction

Road bikes have become expensive, but these two do not follow that pattern. X-Lab is a Chinese bike brand that sells through dealers and bike shops, so buying one works much like walking into a shop for a familiar Western brand, only at a far lower price. Two models arrived for a first look: the AD-9, an aerodynamic road race bike, and the RS-7, a race-inspired everyday road bike. Both came in size large, roughly a 56 cm frame for a 180 cm rider, and both are built almost entirely from X-Lab’s own components, with the Shimano groupsets the main exception.

Why X-Lab Road Bikes Are Worth a Closer Look

X-Lab’s parent company, XDS, has spent years manufacturing bikes for other brands and now runs its own label alongside that work. The result is a range that undercuts established names by a wide margin. The AD-9 as configured, with Shimano Dura-Ace Di2, X-Lab’s own carbon wheels and a one-piece carbon handlebar and stem, costs $8,000, against roughly $14,000 for a top-tier race bike from a familiar brand with the same level of parts. The RS-7 starts from just over $2,000 with a Shimano 105 12-speed mechanical groupset, while the version with 105 Di2 electronic shifting costs $2,800. That is around $1,000 less than a Canyon Ultimate and about $2,000 less than a Specialized Tarmac carrying the same groupset.

A large part of the saving comes from the finishing kit. Wheels, handlebars, saddles and cranksets are all X-Lab’s own, which is the same in-house approach Trek, Canyon and Specialized have taken to control costs. Both bikes also include a power meter, which is unusual at the RS-7’s price point and effectively removes the need to add one later.

X-Lab AD-9: The Aero Race Bike

The AD-9 is the model raced by the Astana team, and this example wears a race replica paint finish, with a regular finish also available. The shaping is conventional aero rather than radical: a deep head tube, a deep down tube with a stepped profile shaped around the aero bottle supplied with the bike, an aero seat tube that hugs the rear wheel, a deep inline aero seat post with a single-bolt clamp, and dropped rear stays that flare out from the seat tube. Through axles and disc brakes are present, along with a one-piece carbon cockpit. The frame also uses a UDH dropout, so a SRAM groupset can be fitted if preferred. Weight came in at just over 6.8 kg for a size large without pedals.

On the road it feels genuinely fast and immediately familiar, with stack, reach, wheelbase and head and seat tube angles all in conventional territory, so it steers and corners much like other race bikes in the class. It is a stiff bike, yet the ride is smoother than the deep tube profiles and deep wheels suggest, helped by 30 mm Michelin tires running with inner tubes. A sturdy out-front computer mount is included, which is increasingly rare on complete bikes.

X-Lab RS-7: The Everyday Race Bike

The RS-7 uses a full carbon frame and fork finished in a topographic paint design, with an aero seat post and aero-inspired down tube and seat tube. It carries a one-piece carbon cockpit, X-Lab’s own carbon wheels wrapped in 32 mm tires, an X-Lab saddle, and a crankset with a dual-sided power meter, this one made from aluminium. The bike weighs around 8.4 kg.

Ride quality is the standout. The 32 mm tires sit plump on the carbon rims and smooth out rough road surfaces better than the aero model, so the RS-7 feels comfortable and composed over long distances. It is noticeably less quick than the AD-9, which is expected given the weight difference and the wider rubber, and it can feel a little sluggish when pushed hard. The fit is racy and sporty rather than endurance-oriented, and there is a generous stack of spacers under the stem, more than some riders will want. Cranks are 170 mm on a size large, and the rear hub freehub is notably loud.

How the Two Bikes Ride

The gap between them is mostly about weight and tires. The AD-9 sits at just over 6.8 kg and feels stiff, quick and smooth at the same time, while the RS-7 at around 8.4 kg prioritises comfort and stability. Both use inline seat posts that push the saddle further forward over the bottom bracket, and both use shorter crank arms than many riders are used to, 165 mm on the AD-9 and 170 mm on the RS-7. That geometry choice feels progressive and keeps the pedalling position efficient.

Tire choice explains much of the difference in feel. The RS-7’s 32 mm tires are the main reason it rides so smoothly, and fitting a more familiar tire in the same width would give a clearer benchmark for how much of that smoothness comes from the rubber rather than the frame. On the AD-9, the 30 mm tires and deep carbon wheels deliver a ride that is firm but never harsh.

Components and Details Worth Knowing

Both bikes ship with X-Lab’s own finishing kit, and the standard of that kit is high. The out-front computer mount on the AD-9 is sturdy and included as standard. The fork tabs on the aero bike are elaborate and drew attention on group rides. The seat clamp uses 3 mm bolts with a maximum torque of 2.5 Newton metres and presses a metal plate into the carbon seat post, and with carbon paste applied it has held position without slipping.

There are a few small points to note. Only one aero bottle is supplied with the AD-9 rather than two, and the flare in the down tube does not perfectly match the bottle’s shape, so a different bottle and cage could suit some riders better. The bar tape is a little slippery with bare hands in warm weather compared with grippier tapes. None of these are deal breakers, but they are worth knowing before ordering.

Fit, Cranks, and Power Meters

Both test bikes are size large, which suits a rider around 180 cm. The RS-7 offers plenty of adjustment room thanks to the spacers under the stem, so the front end can be set higher or trimmed lower to taste. The inline seat posts on both models move the saddle forward, which supports an aggressive position without needing an unusual saddle offset.

The power meters are one of the more interesting inclusions. The AD-9 uses X-Lab’s own unit with a charge port, while the RS-7 uses an aluminium dual-sided design that looks well made. How accurate, reliable and consistent these meters are over time is the open question, and it is the kind of detail that only longer riding and comparison testing will settle.

Shorter cranks are a deliberate part of the fit on both bikes. Riders moving up from a cheaper bike may notice the difference immediately, and the 165 mm arms on the aero model are particularly progressive for a production road bike.

Availability and Value

There is one practical catch: these bikes cannot currently be bought in Europe or the UK, with availability there scheduled for early 2027 at the soonest. For now they are sold in the US through a growing network of dealers and bike shops. Prices at this level appear to be a deliberate attempt to gain market share, which is a familiar playbook. Canyon arrived in the UK around a decade ago with direct sales and very low prices, and those prices have since crept upward while remaining below the biggest names.

That history is worth keeping in mind. Today’s pricing looks exceptional on paper, and the first rides back it up, but how long these prices hold and how the brand develops over the next few years are open questions. Buyers who value dealer support and a physical shop to walk into should find the current US dealer network reassuring.

Buying Advice: Choosing Between the AD-9 and the RS-7

Start with the riding you actually do. The AD-9 is the sharper tool: it is light, stiff, fast and predictable, and it comes with top-level Dura-Ace Di2 and deep carbon wheels at a price that sits far below comparable race bikes. If racing, fast group rides or chasing personal bests are the priority, and the $8,000 asking price fits your budget, it delivers a lot for the money.

The RS-7 is the easier bike to live with day to day. At $2,800 with 105 Di2, or from just over $2,000 with mechanical 105, it offers a carbon frame and fork, carbon wheels, a one-piece cockpit and a dual-sided power meter, with 32 mm tires that make rough roads feel calm. It suits riders stepping up from an entry-level bike who want real performance without a race-focused position or a premium price.

Because both bikes use in-house components, there is nothing that urgently needs upgrading out of the box. The sensible approach is to confirm frame size and fit first, then decide whether the aero advantage of the AD-9 or the comfort and value of the RS-7 matches the riding you have planned. Either way, both represent a genuinely different value proposition to the established brands.

Conclusion

X-Lab is doing something notable: race-ready road bikes with strong specifications, sold through shops, at prices that undercut familiar brands by a wide margin. The AD-9 performs like a proper aero race bike, and the RS-7 delivers comfort and a generous parts list for its price. Availability outside the US is still pending, and long-term questions about power meter accuracy and future pricing remain, but on specification and first impressions both bikes are hard to argue with.
