Carry heavy luggage confidently, with 100KG aluminium load-bearing construction

Aluminium alloy frame and reinforced V-shaped cross bars distribute weight across the platform while the broad panel helps share loads between rack and frame. Quick-release clamp fixes to the seat post and included rubbers smooth the connection to different tube diameters.

Suitable for large panniers and camping kit on multi-day rides, reducing strain on pannier mounts and helping maintain bike stability on rough roads.

Adjustable fit for many frames, with extendable support bars and rubber shims

Support struts extend from 24cm to 45cm to accommodate varying frame geometries, and rubber inserts adapt seat tube diameters under 33mm for a firmer connection. Installation tools and instructions are supplied to aid the process.

Allows fitting to 700c and 650B wheel bikes and other common sizes, giving flexibility for riders who swap bikes or retrofit a rack.

Cleaner, safer rides, with wide platform, reflector and elastic bungee

Wide panelling acts as a fender to deflect water and dirt away from the rider, while a red rear reflector increases visibility at night and an elastic bungee secures cargo to the platform.

Helps keep clothing and kit drier in wet conditions and secures luggage on uneven terrain, useful for commuters and touring cyclists alike.
