The Campagonolo Ekar Crankset 1×13 speed: Built for Gravel Excellence

The Ekar crankset embodies simplicity and performance, making it ideal for gravel riding and racing. Its single-chainring design eliminates the need for a front derailleur, reducing weight, minimizing moving parts prone to dirt or clogs, and ensuring high chain security without redundant gearing overlap.

Durable Strength Meets Lightweight Design

Crafted with unidirectional carbon fiber crank arms and a strong 630-grade steel alloy crank axle, the crankset strikes the perfect balance between durability and low weight – a hallmark of the Ekar groupset. ProTech™ technology securely joins the two semi-axles inside the bottom bracket using a single oversized bolt, enhancing strength and reliability.

Stainless steel bearings are mounted directly on the semi-axles, ensuring maximum smoothness and longevity while remaining easy to access for maintenance or inspection – with no cup extraction required.

Optimized Ring Options for Every Adventure

The crankset offers four chainring size options to suit different riding styles:

• 38T Adventure: For exploratory rides and steep climbs.
• 40T Pure Gravel: A versatile option for all-purpose gravel riding.
• 42T Fast Gravel: Designed for speed on harder-packed surfaces.
• 44T eGravel: Optimized gearing for e-bike applications or higher speeds.

The chainrings feature a narrow-wide tooth profile for efficient power transfer and maximum chain retention. Made from robust, lightweight 7075 aluminum, they’re easy to swap out without disassembling the cranks—simply unbolt from the four asymmetrical spider arms (123mm BCD). This flexibility allows for quick gearing adjustments to suit different terrains and conditions.

Tailored Crank Arm Lengths and Q-Factor

The crankset is available in four arm lengths – 165mm, 170mm, 172.5mm, and 175mm – ensuring the ideal fit for riders of all sizes and styles. For gravel bikes with lower bottom brackets, shorter arms help prevent pedal strikes on uneven terrain.

A narrow 145.5mm Q-factor provides efficient power delivery and comfortable pedaling ergonomics across all rider types. The crank’s UD carbon arms come with removable end caps, protecting the finish from wear and tear while maintaining a sleek appearance, no matter where your ride takes you.

With its blend of thoughtful design, advanced materials, and versatility, the Ekar crankset is your ultimate companion for gravel adventures and racing.
