Fine-Tune Your Ride: Introducing Our New Custom Gravel Drivetrain Offerings!

The heart of any great gravel bike is its drivetrain. It’s the critical link between the power in your legs and the traction on the trail. It dictates how you climb, how you sprint, and how you conquer the diverse terrain that makes gravel riding so addictive. That's why we're thrilled to announce a new range of custom gravel drivetrain options, meticulously curated to offer the perfect blend of performance, reliability, and ride feel for every type of cyclist.

Whether you're a podium-hunting racer, a backcountry explorer, or a Shimano purist, we have a build that will redefine your gravel experience. Let's dive in and find your perfect match.

The SRAM Revolution: Options for Every Gravel Grinder

SRAM continues to push the boundaries of what's possible with wireless electronic shifting. We have three distinct offerings that cater to the specific demands of modern gravel bikes and riders.

1. SRAM Red/Force/Rival XPLR 13-Speed: The Racer's Edge

• Best For: Riders with SRAM UDH-equipped bikes (often with shorter chainstays) looking for tight gearing for gravel racing and fast-paced group rides.

• The Standout Feature: This is the choice for the rider who values cadence above all else. The 13-speed, 10-44t cassette offers smaller, more intuitive jumps between gears compared to wider-range 12-speed options. This means you can always find the sweet spot to keep your power output smooth and efficient, especially on rolling terrain where momentum is key.

• Who It's For: If you're pinning on a number for events like Unbound Gravel or navigating the rolling hills of your local group ride, the XPLR 13-speed system is your competitive advantage. It’s the most race-oriented gravel groupset for those who demand precision and efficiency.

2. SRAM T-Type Mullet (Red XX/Force X0/Rival GX): The Trail Tamer

• Best For: UDH-equipped bikes and riders who want the biggest gear range possible to climb and descend the steepest, most rugged terrain.

• The Standout Feature: Welcome to the future of shifting. The "T-Type" direct-mount design is incredibly robust and allows for flawless shifts even when you're putting down maximum power. Paired with a massive 10-52t cassette, this "mullet" setup (road shifters, mountain bike derailleur/cassette) gives you an unparalleled gear range. It’s the ultimate solution for the demanding climbs and wild descents we love here in Southern California.

• Who It's For: This is for the adventurer who refuses to be limited by their gearing. If your idea of a perfect ride involves exploring unknown fire roads, tackling singletrack sections, and never backing down from a steep grade, the T-Type Mullet is your ticket to ride without boundaries.

3. SRAM AXS Eagle Mullet (Red XX1/Force X01/Rival GX): The Universal Upgrade

• Best For: Riders with non-UDH bikes who still crave a massive gear range and want to upgrade a frame they already love.

• The Standout Feature: Have a beloved gravel frame that isn't equipped with the latest UDH (Universal Derailleur Hanger) standard? This is your answer. This system brilliantly pairs the latest ergonomic AXS levers and powerful hydraulic brakes with the proven performance of the Eagle AXS mountain bike ecosystem. You get the massive 10-50t or 10-52t range to tackle any climb, with a system that can be fitted to virtually any modern gravel bike.

• Who It's For: This is the perfect upgrade path for the cyclist who wants modern performance without needing a brand-new bike. It delivers lightning-fast shifts and incredible range, rewarding a rider who has a bit of finesse with a truly connected and high-performance feel.

The Shimano Standard: Smoothness and Precision

For riders who swear by the silky-smooth feel and legendary reliability of Shimano, we have two exceptional Di2 electronic options that combine cutting-edge technology with rider-focused design.

4. Shimano GRX Di2 / XTR: The Connoisseur's Choice

• Best For: Shimano enthusiasts who demand buttery-smooth shifting, precise braking, and the performance benefits of a lightweight build.

• The Standout Feature: This is the pinnacle of Shimano's gravel offering. The updated Di2 lever ergonomics are more comfortable and secure than ever, while the shifting is so smooth it's almost silent. We offer this in two distinct flavors to suit your style: a race-ready 11-45t cassette or an adventure-focused 10-51t option (Note: the derailleur must match your chosen cassette).

• Limited-Time Promotion: To make this top-tier build even more enticing, we're offering a FREE Easton EC90 SL carbon crankset with the purchase of any GRX/XTR Di2 Gravel Kit for a limited time!

• Who It's For: This is for the rider who appreciates the finer details. If your perfect drivetrain is one you never have to think about—it just works, flawlessly, every time—and you value the significant weight savings of carbon components, this is your ultimate build.

5. Shimano GRX Di2 / XT: The People's Champion

• Best For: Riders who want all the benefits of Shimano's electronic shifting and robust performance at a more accessible price point.

• The Standout Feature: This groupset takes all the incredible technology from its XTR sibling—the flawless Di2 shifting, the powerful braking, the two cassette range options (11-45t or 10-51t)—and packages it in a more value-focused build using the workhorse XT mountain bike components. It's an incredibly robust system designed for riders who prioritize reliability and exploration above all else, with only a minor penalty in overall weight.

• Who It's For: This is for the pragmatic explorer. You want a drivetrain that will stand up to thousands of miles of adventure without fuss and deliver the quiet, smooth performance Shimano is famous for. It's the purist's build for those who believe top-tier function shouldn't come with a top-tier price tag.
