Why buy a Draftmaster or Topper Rack?

Designed by a rocket scientist. The best racks on Earth!


Models for Every Kind of Cycle - We make racks to carry bikes, trikes, tandems, recumbents, and cargo bikes.
If you have to pedal it we probably make a rack to carry it.

All Features Included - Quick installation, easy loading and gentle treatment of your cycles is standard equipment with a Draftmaster or Topper Rack. Extra parts or expensive add-ons are not needed.

Best Materials and Construction - We use our own high-strength aluminum custom extrusions for the best blend of strength, weight and functionality. Our products are specifically engineered for their intended use.

Quality Throughout - Every Draftmaster and Topper Rack is manufactured in the USA by our own employees. Our hands-on approach guarantees our racks will give years of trouble-free service.

Largest and Most Experienced Specialty Rack Manufacturer in the US - Atoc is the #1 source for racks for tandems, recumbents and trikes. We understand the challenges of carrying bikes and trikes of all sizes.

Draftmaster® is the ultimate in receiver rack design.

It’s like a roof rack that’s slid back, tipped up, and mounted to your receiver - only better.

Our quick-connect modular system lets you easily get your Draftmaster out of the way when you are not using it. Also, if your needs vary from ride to ride, or change over time, swapping out modules to suit your needs for the day is a snap.

Atoc is the SPECIALTY RACK SPECIALIST. We have bike mounts and modules to carry everything from tandems, tadpole trikes, delta trikes, long and short recumbents, e-bikes, gravel bikes, small children’s bikes, fat bikes, and cargo bikes. Heck, we even have mounts for classic road bikes.

Got a thru axle front fork? We have you covered. Our unique thru axle direct-mount system eliminates those kludgy adapters and their “roll over” problem.

Need to carry a mix? Combinations are a snap! Whatever your unique bike combination is, we can configure a Draftmaster to carry it. No other rack system is as flexible or adaptable.

Unlike most hitch racks, a Draftmaster gives you full access to all your bikes at any time. Plus you can get into your trunk or hatch without removing any of the bikes.

Got a long bike like a tandem or tadpole trike? Side overhang issues are eliminated with a Draftmaster because your cycles are held vertically "in the draft".

Draftmaster is the complete solution for all your cycle carrying needs.

If it has 2 or 3 wheels and pedals,
a Draftmaster can carry it.

Tandem Topper™ pivoting series

All Tandem Toppers have Atoc's pioneering pivoting fork mount system.

With a Tandem Topper, just one person can easily load, transport, and unload a long bike. Tandem Toppers are available for upright tandems (doubles, triples and even quads), LWB recumbents, recumbent tandems, and cargo bikes.

If your tandem or other long bike has a thru axle front fork, you will want to check out our TTCK series conversion kits. The TTCKs fit all Tandem Toppers and Thule 558p tandem carriers (Thule gets them from us!) made since 2007.

Tandem Toppers can also carry a classic single or other shorter bike without the need for adjustment or modification.

Bike Topper™ non-pivoting series

Bike Toppers have the same high quality as our flagship Tandem Topper but without the pivot feature. Bike Toppers are available in full range of sizes for traditional single bikes up through recumbent tandems and cargo bikes.

If you need extra clearance for fenders, low-rider pannier racks, or disc brakes, check out our “High Topper” model of the Bike Topper.

If it has two wheels and pedals,
a Topper can get it on your roof rack.
