If you’ve ever fumbled for a gel on a rocky descent or cursed a bulky top tube bag for rubbing your knees during a sprint, you’re not alone. That’s exactly why I designed the GelShell—a minimalist, 3D printed gel holder built specifically for gravel riders who value speed, efficiency, and clean cockpit setups.
Designed for Fast Gravel Riding and Racing
When you're riding technical gravel or light singletrack, every movement matters. The last thing you want is to reach for a gel and knock your bike offline—or have a bag bouncing between your knees on a climb.
GelShell was made for riders who:
-
Push the pace on 20 to 60 mile gravel rides
-
Want quick, one-handed access to nutrition at speed
-
Race competitively and care about aero, weight, and efficiency
-
Supplement gels stored in jersey pockets or hydration packs without adding bulk
Why Choose GelShell?
Ultralight (<60g):
At less than 60 grams, GelShell is significantly lighter than most top tube bags—perfect for performance-focused builds.
Low-profile and aerodynamic:
Its small frontal footprint keeps it out of the wind, and out of your way. You won’t notice it when climbing or sprinting out of the saddle.
Quick access, even on technical terrain:
Designed to let you grab a gel with one hand while navigating bumpy roads or fast descents. No zippers, flaps, or digging around.
Secure and stable:
Holds your gels snugly and mounts cleanly to your top tube using reusable hook-and-loop straps or zip ties. No bounce. No rattle.
Who It's For
-
Gravel racers looking for marginal gains and total focus
-
Short to medium-distance riders who need just a few gels within easy reach
-
Bikepackers who want a lightweight, modular supplement to their main bags
-
Anyone tired of thigh rub and cockpit clutter
A 3D Printed Solution Born from Real Rides
GelShell started as a personal solution to a familiar problem. I wanted a cleaner, lighter way to access gels without sacrificing performance. So I prototyped a design, refined it through real-world rides, and now print each unit in-house using high-strength, lightweight filament.
Because it's 3D printed in small batches, I can rapidly iterate, test, and improve. It’s the kind of gear that wouldn’t exist in the big-brand world—but works exactly how you need it to.
