Revelate Underpackers Review: Bolt-Free Cargo Mount for Mountain Bikes | Bikepacking Gear (2026)

The cycling world is always buzzing with innovative gear, and the latest addition to the market is the Revelate Designs Underpackers. These bolt-free cargo mounts are a game-changer for riders seeking a minimalist approach to carrying gear on their bikes. But what sets them apart, and why should you consider adding them to your setup?

A Unique Solution for Wide Downtubes

One of the standout features of the Underpackers is their specific design for carbon and aluminum frames with wide, flat-bottomed downtubes. These downtubes, common on alloy and carbon mountain bikes, often pose a challenge for traditional cargo mounts. Revelate Designs tackled this issue head-on, creating a solution that is both functional and sleek.

Minimalist Design Meets Durability

The Underpackers are crafted with a minimalist approach, utilizing TPU mounts integrated with Voile-style straps. This design not only reduces weight but also ensures a secure hold for your cylindrical gear. Neil's experience on the Colorado Trail highlights the system's adjustability and security, even in rough terrain. The ability to slide the straps up or down allows for a customized fit, and the TPU grips provide a reliable hold, keeping your gear in place without any slippage.

Weight and Reach Benefits

With a weight of just 70 grams per pair, the Underpackers offer a significant weight advantage over traditional cargo cages. This lightweight design is a boon for riders who prioritize every gram on their bikes. Additionally, the easy accessibility of the bottle when needed is a game-changer, providing a practical solution for those seeking both security and convenience.

Practical Specs and Pricing

The included straps measure 18 inches (458mm) in length, accommodating a maximum downtube circumference of 240mm and a 90mm max diameter bottle. This setup is ideal for Nalgene-sized bottles. The Underpackers are not just lightweight; they are also affordable, retailing at $29 USD. This price point makes them an attractive option for riders looking to enhance their bikepacking setup without breaking the bank.

A Must-Consider Accessory

In my opinion, the Revelate Designs Underpackers are a must-have accessory for anyone looking to maximize their bike's cargo capacity while maintaining a minimalist aesthetic. The system's adjustability, durability, and lightweight design make it a top choice for both short and long-distance rides. With the Underpackers, you can focus on the journey ahead, knowing your gear is securely in place.

So, if you're in the market for a bolt-free cargo solution that doesn't compromise on functionality or style, the Revelate Designs Underpackers are definitely worth a closer look.
