The protective spiral wraps are designed specifically for the rearmost wheel support cradles – where contact with the ground can occur when the carrier is lowered. Acting as a durable buffer, the wrap helps preserve the powder coat finish by preventing direct abrasion from rough surfaces.

Manufactured in Australia from high-density polyethylene, the spiral wrap offers excellent UV stability, long fatigue life, and high resistance to both heat and cold. It’s a simple but effective solution to extend the life of your carrier’s components while keeping things looking and performing as they should.

Frame Support Cradles

iSi Frame Support Cradles are designed to keep the bicycle upright while all transport loads are handled through the Four Point Wheel Cradles. Manufactured from solid steel rod, they resist high-frequency vibrations over corrugated roads. A proprietary rubber compound developed in house features a wide, soft, and UV-resistant rubber. The result is unmatched protection for even the most delicate carbon, titanium, or thin-wall alloy frames.

Main Beam

The main beam is the structural backbone of the iSi carrier and is available in both 25° and 40° departure angle configurations at various lengths. With bikes staggered vertically along the beam, this stadium-style layout reduces the rack’s overall length by managing hub-to-hub clearance. This results in the most compact rack profile on the market, minimising rear overhang on the vehicle.

The staggered positioning also provides a clear working field for loading and unloading bikes with no overlapping handlebars or awkward reach-arounds. Designed for 2- or 4-bike configurations, the main beam connects tool-free to the pivot base and can be quickly swapped to a trailer or removed as needed. It’s a rigid, modular foundation that delivers both performance and practicality for serious adventure travel.

Tow Bar Pivot Base Mounts

The iSi Pivot Base is a robust modular hitch mount that comes standard with a high-tensile anti-rattle hitch stabiliser and an integrated auxiliary license plate holder (or optional lightboard). It’s offered in multiple height and length configurations for the best compatibility for different towbar depths​ and clearances for drop-down tailgates or rear swing out doors. Moreover, the modular mounts provide ample departure clearance so your bikes or rack avoid ground strikes. The design also features adjustable mounting positions (with multiple hitch pin holes) for fine-tuning the rack’s position relative to your vehicle, yielding a perfect fit tight to the vehicle while providing and secure wobble-free performance.

Adjustable Quad Contact Wheel Cradles

Each bike is stabilised and secured via our Quad Contact Wheel Cradle system with no clamps, bungees, or tie-downs required. The mandrel bent hoops support the tyre at four points on the tread, locking the bike in position through the wheels. This eliminates any unwanted bike movement or rolling left and right as you travel especially over corrugations or off-road tracks. Each cradle is mounted on a sliding offset sleeve, allowing independent height adjustment to finely control handlebar and saddle clearance. Bikes sit tighter and more securely with a narrower footprint, creating a compact, stable load without compromising ease of loading.
