CyclingDeal Handlebar Extenders For Indoor Bikes

XNX 11.8-Inch Handlebar Extender
The XNX extender emphasizes extra space with an 11.8-inch (30 cm) extension, giving riders room for lights, computers, or phone mounts.

Weighing roughly 1.8 oz for the extension bar and about 0.91 oz for the bracket, the setup remains lightweight while offering robust support. It’s designed to fit handlebars with clamps sized for 31.8 mm or 25.4 mm, making it a flexible option for many road and mountain bikes or indoor setups.
With its aluminum alloy construction, the extender balances durability with lightness. The combination of a secure clamp and lightweight design helps maintain control during intense intervals.

CyclingDeal Handlebar Extenders With Grips
This CyclingDeal bundle combines extender bars with handlebar grips to deliver enhanced comfort during workouts. The same easy-install approach applies, with shims included to accommodate bars from 26 mm to 39 mm. The grips feature an anti-slip diamond rubber surface designed to reduce fatigue and improve shock absorption, contributing to a more comfortable ride. The extender diameter remains at 22.2 mm, matching common bars and allowing a seamless transition from standard grips to extended bars.
In addition to comfort, the packaging notes the extender is built for versatility with a phone holder (not included) that can be mounted at the front of the bars. This makes it an attractive choice for riders who want a single package that extends reach while preserving grip feel and adding practical mounting options for devices and accessories.

ONZILLO Upgraded Bar Ends
ONZILLO bar ends are designed to extend grip and control with a focus on durability and comfort. Constructed from seamless aluminum, they resist corrosion and stand up to rugged riding conditions. The design is about 20% longer than typical bar ends, totaling 16.2 cm, which helps reduce arm and shoulder fatigue over long rides. An ergonomic curved shape with a textured finish further reduces hand fatigue and absorbs some road vibration. The product also features flexible 180° rotation and an inward mounting option, giving riders multiple grip configurations to suit climbing or sprinting styles.
Note that inward mounting may require adjusting shifter position during setup, and some setups may need grips removed to slide the bar ends inside the handlebars. If you want longer reach and more ergonomic options without adding new accessories or large changes to your cockpit, these ONZILLO bar ends offer a practical, durable choice for road, MTB, or mixed-terrain use.
- 20% longer, ergonomic bar ends
- 180° Rotation and inward mounting option

Buying Guide
Key purchase considerations
Compatibility matters most. Measure your handlebar diameter and confirm clamp compatibility (common sizes range from 20 mm to 39 mm). Most extenders are designed for standard road and mountain handlebars (commonly 22.2 mm, 25.4 mm, or 31.8 mm). If you own a compact indoor trainer, check whether the extender supports your clamp size and whether it leaves room for other devices mounted on the bars.
Length and reach
Decide how much extra reach you need. Short extenders improve posture without overextending arms, while longer models (like 11.8″ extensions) create space for devices or additional grips but may require more upper body flexibility to maintain control. For mixed riding (commuting plus training), a modular approach with adjustable lengths offers the most versatility.
Material, weight, and durability
Aluminum alloys provide a strong, lightweight option; carbon fiber elements help reduce weight but may come at a higher price. Consider the riding conditions: off-road or wet weather can influence corrosion resistance. Seamless construction and rust-resistant finishes extend longevity on outdoor bikes, while lighter alloys suit indoor use where weight is less critical.
Installation and compatibility
Review whether installation requires tools, shims, or specific mounting hardware. Some products include complete mounting kits and angle indicators, while others rely on existing bolts. If you anticipate frequent adjustments, prioritize models with straightforward height or angle changes and secure clamps to reduce slippage during aggressive efforts.
Accessory ecosystem
Many extenders support add-ons like phones, lights, or bike computers. If you rely on accessories, choose options with front-mount compatibility or spaces to attach devices without obstructing steering or grip areas. Consider whether the extender allows grip installation on the extender itself, which can increase comfort and control during long rides.
Riding goals and use cases
Indoor cycling, Peloton-style workouts, and outdoor rides each benefit from different configurations. If you frequently switch between devices and grips, prioritize versatile extenders with multiple mounting options and adjustable angles. For riders focused on posture and back relief, look for models offering height adjustment and extended reach without compromising balance.
Across these five selections, the balance between ease of installation, durability, and accessory compatibility will guide the best buy for most riders. Always verify clamp compatibility, installation steps, and warranty terms before purchasing to ensure the extension integrates smoothly with your bike setup and riding style.
