UPANBIKE Flat Bar Handlebar 60cm / 62cm
This UPANBIKE option mirrors the first model with a similar 25.4mm/600mm footprint and a 31.8mm/620mm alternative, emphasising compatibility for a wide range of bikes, including mountain, road, and hybrid builds. Its flat bar design delivers a straightforward, predictable steering response, ideal for riders who want quick handling on light-to-moderate trails and city streets. The 60–62 cm lengths help accommodate taller riders and longer reach preferences for gravel setups that require more cockpit space.

This is a practical choice for users seeking straightforward installation and compatibility with a wide assortment of frames and full-suspension or rigid setups.
RXL SL Gravel Carbon Handlebars
RXL SL offers a carbon gravel handlebar designed for speed and stiffness while maintaining comfort. With a 31.8mm clamp and 458–498mm widths, it supports a low, aerodynamic riding position with a 110mm drop and 77mm reach. Internal routing options on carbon bars help reduce external cable clutter and improve aerodynamics. At around 210 g, weight savings are noticeable for riders prioritising performance on longer gravel rides. Carbon composition provides a blend of lightness and durability suitable for aggressive gravel setups.
Kenilah 14° Carbon Gravel Handlebar
The Kenilah carbon handlebar features a 14° sweep and 130mm drop, engineered for a comfortable, aerodynamic stance on endurance and racing outings. Built from T800 carbon fibre, it offers strength and lightweight performance with a 31.8mm clamp that fits most gravel and road bikes. Compatibility and geometry are well-suited for riders seeking a more aggressive drop while preserving navigation control on rough surfaces. The internal routing option aids in a clean cockpit and efficient cable management.
S SENQI Flat Bar Aluminum Alloy Handlebar
The S SENQI aluminum handlebar combines a frosted finish with a 31.8mm clamp and 690mm maximum width to provide a robust, lightweight option for gravel, touring, and MTB builds. The 22.2mm bar diameter at the mid-section supports comfortable grip zones for long rides, while the wide overall length enhances stability in loose or uneven terrain. This option suits riders who want a budget-friendly, durable flat bar solution with broad compatibility across frames that support 31.8mm clamps.
Buying Guide
Key considerations when selecting a flat bar gravel handlebar or related cockpit components include:
- Clamp diameter and compatibility: Most gravel bikes use 31.8mm, but some models use 25.4mm or 22.2mm. Confirm your stem and fork compatibility before purchasing.
- Width, reach, and drop: Wider bars improve stability on rough gravel, while longer reach and drop influence riding position and aerodynamics. Choose dimensions that suit your torso length and shoulder width for a comfortable, efficient stance.
- Material and weight: Carbon bars reduce weight and can improve vibration damping but may be pricier. Aluminium offers durability at a lower cost and is widely available.
- Internal routing vs. external cabling: Internal routing creates a cleaner look and potentially better aerodynamics, but requires careful setup during installation.
- Riser vs. flat bar choice: Riser bars add vertical height for comfort and control, while flat bars prioritise a lower, more aggressive position. Your riding style and terrain will guide the choice.
- Durability for UK conditions: Look for corrosion resistance and robust construction for wet, muddy rides common in Britain, along with compatibility with mudguards and fenders if needed.
- Budget vs performance: Higher-end carbon options offer weight savings and stiffness, but durable aluminium bars can meet most riders’ needs at a lower price point.
When combining handlebars with mudguards, fenders, or other accessories, ensure all components have compatible mounting points and that installation torque values follow manufacturer recommendations. Proper setup enhances control, comfort, and safety across varied UK terrains, from damp lanes to gravel tracks.
