Stromberg CC-275 Bike Bunk: A–I Parts & Mounting Guide

The Stromberg Carlson CC-275 Bike Bunk bolts to the A-frame of a suitable travel trailer and provides a raised 2-inch receiver for a compatible RV-approved bicycle rack. The Bike Bunk is the receiver structure only; the bicycle rack is purchased separately. Its 100 lb limit includes both the empty rack and the bicycles.

The factory's CC-275 illustrated installation and replacement-parts manual uses drawing callouts A through I. Match those identifiers to the assembly before ordering service parts.

Bike Bunk component numbers A–I

Stromberg also lists 2275 as a replacement hardware package and lists the individual lower pockets, backer bars, support posts and cross tube through its replacement-parts catalog. The original manual identifies backer bars as 7605-117; the manufacturer's later service listing uses 7605-117P. Use the existing assembly and current part reference when obtaining a replacement.

Check trailer fit, loading and clearance

The Bike Bunk is intended for a properly rated RV-approved bicycle rack with a 2-inch receiver shank. Stromberg recommends it primarily for two-place bicycle racks, but physical compatibility depends on rack size and location, the trailer body, propane equipment and the tow vehicle's full turning radius. It is not approved for e-bikes or motorbikes.

Before using the Bike Bunk, add together the weight of the bicycle rack and every bicycle. That combined load must not exceed 100 lb or a lower limit imposed by the rack, trailer structure or tow vehicle. Do not treat the 2-inch receiver as a trailer-towing hitch.

Installation and propane access

1. Locate suitable A-frame mounting positions and verify adequate clearance for propane cylinders, front storage equipment and the trailer body.
2. Position the lower pockets against the frame with backer bars on the opposite side, initially leaving them adjustable.
3. Install the curved posts and cross tube, check the entire tow vehicle/trailer turning sweep with the intended bike rack and bicycles, then follow the manufacturer's drilling and final fastening sequence.
4. Keep propane shutoff valves accessible. A soft tank cover may permit access without removing the crossbar; harder covers can need additional clearance or removal.
5. Check hardware, bike restraints and turning clearance before each trip. Follow the two-person installation procedure specified by Stromberg.
