No product listed here is a complete bike rack that attaches directly to a fifth-wheel pin box. The options instead cover two separate needs: replacement pin boxes for specific fifth-wheel models and adapters designed for the Stromberg Carlson CC-100 Cargo Caddy. The Lippert L07 is best for replacing a 1716 pin box, while the Stromberg Carlson CC-125 is the clearest choice for carrying two bikes on the compatible cargo caddy.

Lippert L07 Retracted Pin Box
The Lippert Components L07 is a replacement pin box configured for 1716 pin boxes. Its listed weight capacity is 15,500 pounds, and its king pin connects to a fifth-wheel trailer hitch. The product description says it bolts onto the trailer using existing hardware and two rows of bolt holes.
Best for: Owners who have confirmed that their trailer uses a 1716 pin box and need a replacement. It is included because it directly addresses the fifth-wheel pin-box part of the search. Limitation: It is not a bike rack or bike-carrying adapter, and the stated configuration is specific to 1716 replacements.
Stromberg Carlson CC-125 Bike Adapter
This adapter is designed for the Stromberg Carlson CC-100 Cargo Caddy and is listed for carrying up to two bikes. It accommodates tires up to 2.25 inches wide. The package includes four tire holders, eight carriage bolts, eight lock nuts, and two tie-down straps.
Best for: RV owners who already have, or are selecting, the specified CC-100 cargo caddy and want to stabilize two bikes. It is the most directly documented bike-carrying option in this list. Limitation: The listed use is with the CC-100; the product information does not establish that it attaches to a fifth-wheel pin box.
Lippert L05 Standard Pin Box
The L05 standard pin box is configured to replace a 1621 pin box and has a listed weight capacity of 15,500 pounds. Lippert states that the king pin connects to a fifth-wheel trailer hitch and that the unit bolts on using existing hardware along two rows of bolt holes.
Best for: Owners replacing a worn or damaged 1621 pin box who have verified the required configuration. It offers a different replacement fit from the L07 and M19. Limitation: It is not intended as a universal pin-box replacement; confirm the existing pin-box model before choosing it.
Lippert M19 Retracted Pin Box
The Lippert M19 is designed to replace a 1116 pin box and has a stated weight capacity of 19,000 pounds. Its description says the king pin connects to a fifth-wheel trailer hitch and the unit bolts into place along two rows of holes using existing hardware.
Best for: Owners whose trailer requires a 1116 replacement and who need the listed 19,000-pound capacity. It is the highest-capacity pin-box option among the products covered here. Limitation: Capacity alone does not establish fit; verify the trailer’s pin-box configuration and requirements before purchase.
Famiron CC-125 Two-Bike Adapter
The Famiron adapter is a four-piece kit intended for use with the CC-100 Cargo Caddy. It includes hardware to stabilize two bikes and accommodates tires up to 2 inches wide. The listed construction is steel with a black coated finish.
Best for: Buyers using the compatible cargo caddy with bikes that have tires no wider than 2 inches. Choose it over the Stromberg Carlson adapter only if its stated tire-width limit suits your bikes. Limitation: Its tire-width allowance is narrower than the Stromberg Carlson option’s, and it is not described as a pin-box-mounted rack.
Buying Guide: How To Choose A Pin Box Or Bike Adapter
Does a pin box bike rack attach to the pin box?
Do not assume these products create a pin-box-mounted bike rack. The listed pin boxes are trailer components for specific replacement configurations. The CC-125 products are bike adapters designed for the CC-100 Cargo Caddy. Check the product’s stated mounting system before buying, and confirm any proposed rack arrangement with its manufacturer.
Which pin-box model should you select?
Start by identifying the pin-box model currently installed on the trailer. The L07 is configured for 1716 replacements, the L05 for 1621, and the M19 for 1116. Compare the required model and capacity with the trailer’s documentation; the capacity figures do not make these models interchangeable.
How do you choose between the bike adapters?
Both the Famiron and Stromberg Carlson options are described for the CC-100 and two bikes. The Stromberg Carlson adapter lists tire widths up to 2.25 inches, while the Famiron lists widths up to 2 inches. Check tire width and confirm the included hardware and mounting arrangement suit your cargo caddy.
What should you verify before carrying bikes?
Confirm that the rack or adapter is installed as directed, that the bike tires fit its holders, and that the cargo carrier and vehicle setup can support the intended load. The supplied product details do not state a bike-weight limit for these adapters, so do not infer one from the number of bikes they accommodate.
