X-LAB RS5

X-Lab RS75 - Alloy Road Bike 105

X-Lab RS7 Endurance Road Bike – Shimano 105 Road Bike at Bike Attack

Performance, comfort, and modern road-bike technology come together in the X-LAB RS5.

The X-LAB RS5 Alloy Endurance Road Bike brings the distinctive X-LAB riding experience to a versatile aluminum platform designed for riders who want speed, comfort, reliability, and exceptional component value.

Built around a durable XDS X6 aluminum alloy frame and lightweight XDS carbon fork, the RS5 combines responsive road performance with endurance-oriented versatility. Its clean, semi-integrated cockpit, aero-profile carbon seatpost, Shimano 105 drivetrain, hydraulic disc brakes, generous tire clearance, and standard-equipped Branta power meter crankset make the RS5 an exceptionally well-equipped road bike for training, recreational riding, commuting, fitness riding, and long-distance road adventures.

Whether you're buying your first performance road bike or looking for a capable endurance bike that doesn't require immediately adding expensive upgrades, the X-LAB RS5 is built to make every mile smooth, responsive, and rewarding.

WHY CHOOSE THE X-LAB RS5?

The RS5 is designed around a simple idea: a modern road bike should be fast and responsive without forcing the rider to sacrifice comfort or everyday usability.

The X6 alloy frame provides a durable foundation, while the carbon fork helps create a responsive front end and reduces unnecessary weight. The combination makes the RS5 suitable for everything from weekday fitness rides to longer weekend routes.

A Branta semi-integrated alloy cockpit gives the bike a clean, modern appearance, while the XDS aero-profile carbon seatpost adds another premium component to the build.

The result is an endurance road bike that looks refined, feels composed on the road, and offers equipment normally associated with significantly more complicated builds.

SHIMANO 105 12-SPEED PERFORMANCE

At the heart of the X-LAB RS5 is a Shimano 105 12-speed drivetrain, one of Shimano's best-known road groupsets.

The RS5 features:

• Shimano 105 RD-R7100 rear derailleur

• Shimano 105 FD-R7100 front derailleur

• Shimano 105 ST-R7120 shifters

• 52/36T double crankset

• 11-34T 12-speed cassette

The wide gearing range gives riders plenty of options for maintaining speed on flatter roads while providing lower gearing for climbs and longer endurance routes.

For riders moving into higher-performance road cycling, Shimano 105 offers an excellent balance between performance, reliability, serviceability, and long-term usability.

BUILT-IN POWER METER

One of the most distinctive features of the X-LAB RS5 road bike is its standard-equipped Branta Alloy Power Meter Crankset.

Instead of purchasing a separate power meter later, riders can begin using power-based training data with the equipment already integrated into the bike.

Power measurement can be especially useful for riders interested in structured training because it allows cyclists to monitor actual riding output rather than relying solely on speed, heart rate, or perceived effort.

The crankset features:

52/36T gearing
24 mm steel spindle
Integrated power meter

For riders who want to train more efficiently or simply understand their cycling performance better, the integrated power meter adds considerable functionality to the RS5.

APPLE FIND MY ANTI-THEFT TECHNOLOGY

The Branta crankset also incorporates Apple Find My technology, adding another useful feature to the RS5.

This integration provides compatible Apple users with an additional way to locate the bicycle through Apple's Find My ecosystem.

It is an unusually sophisticated feature to find integrated directly into the crankset of an alloy endurance road bike and further distinguishes the RS5 from many conventional road-bike builds.

X6 ALUMINUM ALLOY FRAME

The RS5 uses an XDS X6 Alloy Frame designed to combine durability, performance, and everyday practicality.

The frame is also UDH compatible, bringing a modern derailleur-hanger standard to the platform.

Aluminum remains an excellent material for road cyclists who want a durable performance bicycle without necessarily moving into the price range of a full-carbon frameset.

Paired with the RS5's carbon fork and carbon seatpost, the alloy frame becomes part of a balanced package focused on performance, comfort, and versatility.

CARBON FORK

Up front, the RS5 features an XDS carbon fork with a 100x12 mm thru-axle.

The carbon fork complements the aluminum frame while helping provide precise steering and confident front-end handling.

The thru-axle design also provides a solid interface between the fork and front wheel, particularly important on a modern disc-brake road bicycle.

SHIMANO 105 HYDRAULIC DISC BRAKES

Confident braking is essential on a performance road bike, particularly when descending, riding in traffic, or dealing with changing road conditions.

The RS5 is equipped with Shimano 105 BR-R7170 brakes and 160 mm front and rear rotors.

The hydraulic disc-brake system gives riders controlled braking performance without relying on traditional rim brakes.

That makes the RS5 well suited to riders who expect their road bike to handle more than perfectly dry, flat pavement.

700x32C TIRES WITH CLEARANCE UP TO 38C

The X-LAB RS5 comes equipped with Branta R332 700x32C tires.

The 32 mm tire size provides a useful balance between rolling performance, stability, and comfort for contemporary endurance-road riding.

Even more importantly, the frame offers maximum tire clearance up to 38C.

That additional clearance gives riders flexibility when selecting replacement tires and allows the RS5 to be configured for greater comfort or less-than-perfect road surfaces.

For riders who encounter cracked pavement, rough urban streets, longer-distance routes, or occasional imperfect surfaces, wider-tire compatibility can make a substantial difference in overall ride quality.

BRANTA A35 SL ALLOY WHEELSET

The RS5 rolls on a Branta A35 SL alloy wheelset, paired with its 700x32C Branta tires.

The alloy wheel platform complements the bike's emphasis on durability, reliability, and versatile real-world road performance.

AERO CARBON SEATPOST

An XDS carbon seatpost with an aero profile provides another premium detail on the RS5.

Combined with the integrated cockpit and clean frame design, the aero-profile seatpost helps give the RS5 the refined appearance of a modern performance road bike while maintaining its endurance-oriented versatility.

WHO IS THE X-LAB RS5 FOR?

The X-LAB RS5 Shimano 105 road bike is an excellent choice for riders looking for one bicycle capable of handling a wide range of road riding.

It is particularly well suited for:

• New riders entering performance road cycling

• Recreational road cyclists

• Fitness riders

• Long-distance and endurance riders

• Riders upgrading from an entry-level road bike

• Cyclists who want Shimano 105 components

• Riders interested in power-based training

• Cyclists who prefer an aluminum frame with carbon components

• Riders who want wider tire capability

• Commuters who want a fast performance-oriented road bike

• Riders looking for an endurance road bike with modern technology
