The Best Bike Racks for Gravel Bikes (Fat Tires Welcome)

Gravel tires are wider than road tires and don't fit standard trays. I tested racks to find the ones with real clearance.

The Contenders

I'm not doing a roundup. I'm doing a head-to-head. These are the four racks that actually showed up with real clearance:

I tested all four over three weeks. I loaded bikes in the dark, I drove at 75 mph, I hit a pothole on I-70 that made me apologize to my wheels. Here's what I learned.

Küat Sherpa 2.0

The Sherpa 2.0 was the first rack I've used that didn't make me nervous with fat tires. The trays measure 46 inches long, and the tire channel is wide enough for a 29x2.4" without touching the sides. That's real clearance, not the "fits most bikes" marketing lie.

Assembly took 12 minutes out of the box. The tool-free tilt lever is actually tool-free, which is rare. The rack weighs 51 pounds, which is heavy but manageable. Loading a bike takes about 20 seconds once you've done it twice.

Here's the criticism: the anti-wobble system is a joke. The included bolt that tightens against the hitch is the same design I've seen fail on three racks over the years. I replaced it with a standard 1/2" bolt and a lock washer, and now it's rock solid. That's a $600 rack that needs a $2 hardware store fix.

The other thing: the Sherpa doesn't fold flat against the vehicle when not in use. It folds up, but it sticks out about 24 inches from the hitch. If you park in a garage, that's a problem.

Price: $599 Who should buy: The gravel rider who wants a rack that will still work when they upgrade to a mountain bike, and who doesn't mind a quick hardware fix.

RockyMounts BrassKnuckles

This one surprised me. The BrassKnuckles is $150 cheaper than the Sherpa, and it does almost everything the Sherpa does. The trays are 43 inches, slightly shorter than the Sherpa but still long enough for a 700x45c. The tire channel clears a 2.4" knobbie with about half an inch to spare.

The big difference is the wheel chocks. They're made of a harder plastic that grips the tire better than the Sherpa's rubber. I loaded the gravel bike with muddy tires and it locked in place with zero drama. That got my attention.

Assembly took 15 minutes, mostly because the instructions are goofy. The exploded diagram shows parts at angles that don't match reality. I've built IKEA furniture with better documentation. But once I figured it out, it went together fine.

The criticism: the BrassKnuckles uses a ratcheting strap system that's finicky. The ratchet mechanism is plastic, and it feels like it's going to strip if you over-tighten. I've seen three Amazon reviews saying the same thing. It's a real weakness, not a one-off.

Also, the rack doesn't come with a lock for the bikes. The Sherpa includes a cable lock; the BrassKnuckles doesn't. For a rack at this price, that's cheap.

Price: $449 Who should buy: The gravel rider who wants most of the Sherpa's performance for less money, and who's willing to replace the plastic ratchet when it eventually fails.

Thule EasyFold XT

I wanted to hate this rack. It's $799, which is more than I've paid for some bikes I've owned. But I can't deny the numbers.

The EasyFold XT is the only rack in this test that handles a fat tire without any adaptation. The tray is 47 inches, and the tire channel is wide enough for a 4.8" fat bike. I tested it with a friend's fat bike and it cleared with room to spare. No other rack in this test can say that.

The ramp is the real story. It folds out and slides into the tray, so you can roll a bike up instead of lifting it. My gravel bike weighs 22 pounds, so I don't need a ramp. But if you've got a 40-pound e-gravel bike, this is the difference between using the rack and hating it.

The criticisms are real, though. The rack weighs 54 pounds, heavier than the Sherpa. And the integrated wiring harness is a pain. The lights on the rack are nice, but the connector is proprietary. If you break it, you're buying a new wiring kit, not a standard plug.

Also: the EasyFold XT only holds 2 bikes, same as everything else here, but it's 66 inches wide when loaded. That's wider than my car. Parking in a tight spot becomes a negotiation.

Price: $799 Who should buy: The gravel rider with an e-bike or a fat bike who needs the ramp and doesn't blink at the price.

Saris Freedom 2

I said I wouldn't review trunk straps. I've used them, they scratch paint, and the only question is whether you care about your paint. But the Saris Freedom 2 keeps coming up in gravel forums because it's cheap and it claims to fit "almost all vehicles."

The claim is a lie. It fit my Honda Fit, but the straps rested right on the paint seams. After three test loads, I could see rub marks. The rack also wobbles at 45 mph. At 60 mph, I pulled over and took it off.

The tire clearance is fine for a 45c, but that's not the problem. The problem is the whole concept. Trunk straps are for occasional use on a bike you don't care about. My gravel bike cost more than this rack, and I'm not strapping it to a piece of painted metal with velcro and hope.

Price: $169 Who should buy: No one with a gravel bike. If you're on a budget, save another $100 and get a used tray rack.

How They Stack Up

Here's the direct comparison on the three points that matter:

Price: The BrassKnuckles wins at $449. The Sherpa is $150 more for a cable lock and a better ratchet. The EasyFold is $350 more for a ramp and fat bike clearance.

Durability: The Sherpa and EasyFold will outlast the BrassKnuckles. The plastic ratchet on the BrassKnuckles is a known failure point. I've seen three reviews saying the same thing. The Sherpa's anti-wobble bolt is a joke, but it's a $2 fix. The EasyFold's wiring harness is proprietary, which is a bigger problem long-term.

Real-world numbers: The EasyFold handles the widest tires (4.8" tested). The Sherpa and BrassKnuckles both clear 2.4". The Saris clears a 45c but wobbles at 45 mph. The Sherpa is 51 pounds, the EasyFold is 54, the BrassKnuckles is 47.

The Winner

The Küat Sherpa 2.0 is the best rack for gravel bikes. It clears the tires that matter, it's easy to load, and the $2 hardware fix solves the one real problem. Over five years of weekend riding, it costs about 33 cents a day. The BrassKnuckles costs 25 cents a day, but you'll be replacing the ratchet by year two.

The Runner-Up

The RockyMounts BrassKnuckles is the value pick. It clears a 45c and a 2.4" without drama, and it's $150 cheaper than the Sherpa. If you're willing to replace the plastic ratchet with a metal one when it fails, you've got a rack that does 90% of what the Sherpa does for 75% of the price.

Who Should Buy What

Buy the Küat Sherpa 2.0 if you want a rack that will still be working in five years and you don't mind a quick hardware store trip on day one.

Buy the RockyMounts BrassKnuckles if you're on a budget and you're handy enough to swap a ratchet.

Buy the Thule EasyFold XT if you've got an e-bike or a fat bike and you need the ramp. It's the only rack here that handles both without adaptation.

And whatever you do, don't buy the Saris Freedom 2. I've got the paint scars to prove why.
