CUBE Bottle Cage HPP Sidecage – Engineered Bottle Access for Compact Frames
Small frame sizes, compact geometries, and modern frame designs with sloping top tubes create a persistent challenge: insufficient clearance between the bottle cage and frame for traditional top-loading bottle access. The CUBE HPP Sidecage solves this problem with a purpose-designed side-loading configuration that delivers secure bottle retention whilst enabling easy lateral access when vertical clearance is limited.
The Side-Loading Solution
Traditional bottle cages require you to lift bottles vertically upward for removal. This works perfectly when there’s adequate clearance between the cage and the frame’s top tube or downtube junction. However, on smaller frames (typically XS and S sizes), sloping-top-tube designs, and bikes with compact front triangles, this vertical clearance simply doesn’t exist. Attempting to use standard cages on these bikes results in frustratingly trapped bottles that can only be removed by tilting the bike or performing awkward manoeuvres.
The HPP Sidecage eliminates this frustration through its side-loading design. The cage opens laterally, allowing you to insert and remove bottles horizontally from the side rather than vertically from the top. This fundamental design change makes bottle access possible on frames where traditional cages would be essentially unusable.
Optimised Geometry for Small Frames
The Sidecage features a carefully engineered profile that addresses the unique requirements of side-loading whilst maintaining secure bottle retention. The cage’s opening faces sideways, with the bottle sitting securely in the cradle formed by the curved arms.
The geometry creates a positive retention force that holds bottles firmly during riding whilst still allowing them to be pushed in and pulled out laterally with reasonable effort. You won’t experience bottles bouncing out on rough terrain, yet you can still access hydration quickly when needed. This balance is crucial – too loose and bottles eject themselves on bumpy descents; too tight and bottles become difficult to extract whilst riding.
20mm Slotted Mounting Hole
The Sidecage includes a thoughtful feature that significantly expands its versatility: a 20mm vertical slot in the mounting area. Unlike conventional cages with fixed round mounting holes, the slotted design allows you to adjust the cage’s vertical position by up to 20mm without requiring different frame mounting points.
This adjustability proves invaluable when fine-tuning bottle position for optimal access. You can position the cage precisely where it works best for your frame geometry, riding position, and bottle size. If you’re using shorter 500ml bottles, you might position the cage slightly higher. With taller 750ml bottles, you can shift it lower to ensure the bottle clears the frame’s top tube.
The slotted design also helps accommodate frames with slightly non-standard bottle cage mounting spacing. If your frame’s bottle bosses are positioned unusually high or low, the slot provides adjustment latitude that fixed-hole cages cannot offer.
Why Small Frames Need Side-Loading Cages
Frame size matters profoundly for bottle cage accessibility. A traditional cage that works perfectly on a size Large frame becomes essentially useless on an XS frame due to geometry differences:
Smaller frames have shorter seat tubes, which means less vertical distance between the bottle cage bosses and the point where the top tube intersects the seat tube. This reduced clearance prevents vertical bottle removal.
Modern frame designs often feature dramatically sloping top tubes for aesthetic and performance reasons. These sloping tubes intrude into the bottle access area, blocking vertical extraction even on medium-sized frames.
Compact women’s-specific frames and children’s bikes face the same challenge – there simply isn’t room to lift bottles straight up.
Riders on these frames have three options: accept difficult bottle access with traditional cages, carry bottles in jersey pockets or frame bags (both inconvenient), or use a side-loading cage like the HPP Sidecage. The latter provides the convenience of a frame-mounted bottle without the access frustrations.
Secure Retention Through All Riding
Despite its lateral opening, the Sidecage maintains impressive bottle security. The curved arms wrap around the bottle circumference at multiple points, creating a secure cradle that prevents accidental ejection. The retention force is calibrated to hold bottles firmly through rough terrain, sudden accelerations, and even when bikes are inverted or lying on their sides.
Mountain bikers will appreciate that bottles stay put through rock gardens, root sections, and drops. Road riders can sprint out of the saddle without worrying about bottles bouncing free. Gravel cyclists can tackle corrugated surfaces confidently knowing hydration remains secured.
The cage works reliably with all standard bottle sizes, from compact 500ml bottles to full 750ml versions. It also accommodates slightly wider insulated bottles, though very large diameter thermoses may be tight.
Multiple Colour Options
The Sidecage is available in numerous colour options, allowing you to coordinate with your bike’s frame colour, components, or personal aesthetic preferences.
Colour is integrated throughout the material rather than being surface-applied, so it won’t chip or fade with use. Your cages will maintain their appearance through years of regular riding and cleaning.
Lightweight Plastic Construction
At 40 grams per cage, the Sidecage adds minimal weight whilst solving a significant practical problem. The slightly heavier weight compared to the standard HPP cage (36g) reflects the additional material required for the side-loading geometry, but the difference remains negligible for real-world riding.
The engineering plastic construction offers durability, corrosion resistance, and flexibility. Unlike metal cages that can bend permanently from impacts, the plastic material flexes and returns to shape. This resilience contributes to long-term reliability and consistent bottle retention characteristics.
Plastic cages won’t scratch bottle finishes, won’t corrode from exposure to spilled energy drinks or weather, and remain comfortable to touch in extreme temperatures. These practical advantages make plastic an excellent choice for bottle cages despite being less prestigious than carbon or titanium alternatives.
Standard Mounting Compatibility
The Sidecage mounts via the industry-standard two-bolt pattern using M5 bottle cage bolts. The bolt spacing matches conventional specifications, ensuring compatibility with virtually all bikes featuring bottle cage bosses. Installation requires only a 4mm hex key and takes minutes.
The cage sits flush against the frame when properly installed, with the mounting area having sufficient material thickness to resist cracking around the bolt holes even when firmly tightened.
