Cube Attain C62 SLT Review: The £3,199 Road Bike That Rivals Bikes Costing Twice as Much

Here’s a mind-bending fact: The 2026 Cube Attain C62 SLT costs £3,199 complete. The Shimano Ultegra Di2 12-speed groupset alone has an RRP of £2,328.

Let that sink in. You’re getting an entire carbon fiber road bike—weighing under 8kg with premium components—for just £871 more than the drivetrain alone would cost you.

How is this possible? Is Cube cutting corners somewhere? After thorough examination, the answer is surprisingly no. This is one of the most requested bikes from cycling enthusiasts for good reason: it delivers World Tour-level performance at a fraction of World Tour pricing.

The Cube Attain C62 SLT is Cube’s most relaxed road bike, positioned below their race-oriented Litening Arrow and Litening Air (used by Total Energies WorldTour team). But don’t mistake “relaxed” for “slow.” This endurance road bike combines race bike performance with touring bike comfort, proving that comfort and speed are indeed two sides of the same coin.

What is the Cube Attain C62 SLT?

Bike Category & Positioning

The Attain series represents Cube’s endurance road bike lineup. In their range hierarchy:

• Litening Arrow/Air: Race bikes for WorldTour performance
• Attain C62 SLT: Endurance road bike for enthusiasts and long-distance riders
• Lower Attain models: More affordable aluminum and entry-level options

The C62 SLT sits at the top of the Attain lineup, featuring:

• Full carbon frame
• Carbon fork
• Premium component specification
• Under 8kg total weight
• Tire clearance up to 34mm

Design Philosophy: Endurance With Performance Intent

Cube’s Own Description: “Race bike performance and touring bike comfort.”

What This Actually Means:

• Slightly more relaxed geometry than pure race bikes
• Enhanced comfort for all-day riding
• Still aerodynamically optimized (CFD-developed shapes)
• One eye firmly on performance (no unnecessary weight)

Not Your Typical Endurance Bike: Unlike many endurance bikes loaded with bikepacking features:

• No bumps or mounts on the fork for bags
• No top tube storage
• Clean, performance-focused aesthetic
• Minimal touring concessions

However, it does include:

• Frame-integrated bag mounting points (compatible with Acid bags)
• Space for proper saddle bag
• Practical storage without compromising looks

Frame & Fork: Carbon Construction Done Right

Frame Design

Material: Full carbon fiber construction Weight: Complete bike under 8kg (exceptionally light for the price) Tube Profiles: Slim, comfort-oriented shapes (not deep aero tubes)

Design Highlights:

Slim Seat Stays: Cube specifically engineered very slim seat stays at the rear for all-day comfort regardless of road conditions. Thinner stays flex more, absorbing road vibrations before they reach your body.

Moderate Tube Depths: Unlike race bikes with deep I-beam-style tube profiles, the Attain C62 uses moderate depth tubes that:

• Flex and absorb vibrations better than deep sections
• Provide classic round-tube comfort characteristics
• Still benefit from computational fluid dynamics (CFD) optimization
• Balance aerodynamics with compliance

Why This Matters: Deep tube profiles act like I-beams—structurally rigid but transmit every vibration. Endurance bikes with very deep tubes aren’t truly comfortable, regardless of marketing claims. Cube’s moderate approach delivers genuine comfort.

Seat Tube Design: Really nice and slim, specifically designed to flex as the rear wheel hits bumps. This deflection absorbs impacts before they reach the saddle, keeping your posterior comfortable on rough roads.

Fork Construction

Material: Full carbon fiber Tire Clearance: Up to 34mm (generous for modern road standards) Trail: More trail than race bikes (front wheel further forward)

Benefits:

• Increased stability (less twitchy handling)
• Better for long-distance comfort
• Confidence-inspiring on descents
• Suitable for varied road conditions

No Mounting Points: Clean fork design without bumps or mounts for bags/panniers. This keeps the bike’s performance focus clear while maintaining aesthetic cleanliness.

Geometry: Endurance Done Properly

What Makes Endurance Geometry Special?

The Attain C62 sits between an all-road bike and a road race bike—a “halfway house” that makes sense for the majority of riders.

Key Geometric Features:

Taller Head Tube:

• Allows comfortable upright position
• Enables running stem lower with fewer spacers
• Better aesthetics (no “chimney” of spacers)
• Comfortable without looking ungainly

Longer Wheelbase:

• More stable platform
• Less twitchy than race bikes
• Better for endurance rides and descending
• Planted feel on rough roads

Increased Fork Trail:

• Front wheel positioned further forward
• Enhances stability significantly
• Reduces nervous handling
• Confidence-inspiring steering feel

Real-World Riding Position

Note on Test Bike: The review bike had significant spacers under the stem (hence the purple/blue finish looking elevated). This was because:

• It’s a demo/review bike that can’t be permanently modified
• Prevents the “chimney” look that would occur with a slammed stem
• Your personal bike would be customized to your measurements

For Most Riders: The taller head tube means you can achieve a comfortable position while still running a relatively aggressive stem height—the best of both worlds.

Components: Premium Specification Throughout

This is where the Cube Attain C62 SLT truly shines. Cube hasn’t cut corners on components—unusual for bikes at this price point.

Shimano Ultegra Di2 12-Speed Groupset

RRP of Groupset Alone: £2,328 Specification: Full Ultegra Di2 12-speed

What You’re Getting:

• Electronic shifting (Di2)
• 12-speed rear cassette (wide gear range)
• Top-tier performance levels
• Only marginally heavier than Dura-Ace
• No performance penalty vs. Dura-Ace

Ultegra vs. Dura-Ace:

• Dura-Ace: Few hundred grams lighter, significantly more expensive
• Performance difference: Virtually zero
• Value proposition: Ultegra offers 95% of Dura-Ace at 33% of the price

Bottom Line: This is top-tier WorldTour performance on a bike costing a third of what professional teams ride.

Newmen Advanced A50 Carbon Wheels

Specification:

• Full carbon fiber construction
• 50mm rim depth
• Modern U-shaped profile
• Proper internal and external widths
• Tubeless-ready

Why These Wheels Matter:

The Problem With Many Bikes: Manufacturers often spec carbon wheels that are:

• Narrow internal widths (outdated 5+ years ago)
• Poor aerodynamics
• Incompatible with modern wider tires
• Essentially cheap marketing gimmicks

Newmen’s Approach: These are modern, performance-oriented carbon wheels that actually make sense:

50mm Depth:

• Perfect for most riders in all conditions
• Modern U-shaped 50mm wheels are stable enough for nearly any weather
• Aerodynamic benefits without handling penalties
• Versatile for flat roads and climbs

Internal Width:

• At least 21mm internal width (critical spec)
• Proper support for 28-32mm tires
• Matches modern tire sizing standards

External Width:

• Wide carbon rim profile
• Properly sized for 30mm tires fitted as standard
• Follows the 105% rule (external width should be 105% of measured tire width)

The 105% Rule Explained: For optimal aerodynamics and handling:

• Measure your tire width (e.g., 30mm)
• External rim width should be 105% of tire width (31.5mm)
• Ensures tire and rim work together aerodynamically
• Prevents “lightbulb” effect of narrow rims with wide tires

Refreshing Honesty: It’s genuinely refreshing to see a manufacturer spec wheels that make sense for the bike’s intended use. Why put 28-32mm tires (endurance bike standard) on skinny rims? Cube got this right.

Continental Grand Prix 5000 S TR Tires

Specification:

• Continental GP5000 S TR (Tubeless Ready)
• 30mm width (actually measures 30mm, not marketing fiction)
• WorldTour-level performance rubber

Why This Is Exceptional:

The Tire Scam: Most bike manufacturers cheap out on tires, knowing buyers will upgrade immediately. They spec:

• Heavy budget tires
• Poor rolling resistance
• Inferior grip
• Tires you immediately replace

Cube’s Approach:

• WorldTour-level performance tires as standard
• Continental GP5000 (the benchmark road tire)
• Proper 30mm width for comfort and speed
• Tubeless-ready for modern setup options

GP5000 Credentials:

• Used by professional WorldTour teams
• Excellent rolling resistance
• Superior grip in wet and dry
• Durable construction
• Costs £60+ per tire retail

This Alone Saves £100+ vs. Budget Tires

Integrated Aero Stem & Cockpit

Stem Design:

• Integrated aero stem
• Internal cable routing
• Clean aesthetic lines
• Aerodynamic gains (every watt counts)

Cable Routing: Cables route through the stem internally, creating:

• Visual cleanliness
• Reduced aerodynamic drag
• Professional appearance
• Protected cables

Not Overly Proprietary: While the stem is integrated, the rest of the cockpit remains serviceable with standard parts.

Carbon Handlebars

Material: Full carbon fiber construction Benefit: Weight savings, vibration damping, stiffness where needed

Modern carbon bars provide excellent combination of:

• Compliance in the drops (comfort)
• Stiffness for sprinting and climbing
• Weight reduction vs. aluminum

Newman Nuance Pro Saddle

Design: Short-nosed saddle. Trend: Increasingly popular modern saddle shape

Short-Nosed Benefits:

• More freedom of movement
• Better for aggressive positions
• Less pressure on soft tissue
• Preferred by many performance riders

Personal Fit Note: Saddles are highly personal. What works for one rider may not work for another. The included saddle is quality, but budget for your preferred saddle if needed.

Standard 27.2mm Seatpost

Specification: Round profile, standard 27.2mm diameter carbon seatpost

Why This Matters:

The Trend Toward Proprietary: Many modern bikes use:

• Squared-off aero seatposts
• Proprietary diameters
• Integrated clamp systems
• Marginal 0.003-watt advantages

Cube’s Pragmatic Approach: Standard 27.2mm means:

• Easy to replace if needed
• Compatible with any aftermarket seatpost
• No proprietary lock-in
• Still high-quality carbon construction

The Performance Reality: Squared aero seatposts save approximately 0.003 watts. For 99.9% of riders, this is completely irrelevant compared to the flexibility of standard sizing.

Paint & Aesthetics: Purple or Blue?

Color Options: The review bike featured a stunning purple/blue chameleon finish

Observer Notes:

“Do you reckon it’s purple or blue? It’s quite purple from this angle. It’s a nice paint job.”

The paint shifts between purple and blue depending on viewing angle and lighting—a sophisticated, eye-catching finish that stands out without being gaudy.

Build Quality: Clean lines, professional finish, attention to detail throughout. This doesn’t look like a budget bike pretending to be expensive—it looks premium because it is.

Riding Experience & Performance

Comfort: The Primary Mission

Slim Seat Stays: Designed to flex and absorb bumps, providing all-day comfort no matter the roads you’re riding on. This isn’t marketing—the tube shaping genuinely delivers.

Moderate Tube Profiles: Unlike race bikes with rigid deep-section tubes, the Attain’s moderate profiles:

• Flex appropriately to absorb vibrations
• Replicate classic round-tube comfort
• Still aerodynamically optimized via CFD
• Balance speed with compliance

Geometry Benefits:

• Longer wheelbase smooths out rough roads
• Taller head tube reduces back strain
• Increased fork trail enhances stability
• Less fatigue on long rides

Tire Contribution: 30mm Continental GP5000 tires at appropriate pressures provide:

• Excellent bump absorption
• Lower rolling resistance than narrower tires
• Confidence in corners
• Comfortable ride quality

Handling: Stable, Not Nervous

Characteristics:

• Slightly longer wheelbase than race bikes
• Increased fork trail
• Stable descending
• Confidence-inspiring cornering
• Less twitchy than pure race bikes

Best For:

• Long endurance rides
• Sportives and gran fondos
• Mixed road surfaces
• Riders prioritizing comfort over razor-sharp race handling

Not Ideal For:

• Criterium racing (requires twitchy handling)
• Technical crit courses (longer wheelbase less maneuverable)

For 99% of riders doing 99% of riding, this handling balance is preferable to twitchy race bikes.

Performance: Genuine Speed

Weight: Under 8kg complete (impressively light) Aerodynamics: CFD-optimized frame shapes Drivetrain: Shimano Ultegra Di2 (WorldTour performance) Wheels: 50mm carbon with modern profiles Tires: Continental GP5000 (low rolling resistance)

Real-World Speed: This bike is genuinely fast. The endurance geometry doesn’t mean slow—it means:

• Sustained speed over long distances
• Less fatigue = more power late in rides
• Aerodynamic efficiency from optimized shapes
• Lightweight for climbing

Comparison to Race Bikes: On a 100km ride, you might be 30 seconds slower than a pure race bike. But you’ll arrive fresher, more comfortable, and able to ride again tomorrow. That’s the endurance bike advantage.
