    Thule Circuit Fork Mount Bike Carrieris rated3.875out of5by8.
    Rated5out of5byfromGreat product, but, yes, security issuesThis carrier works very well. I use it for mountain biking, and never had an issue. However, others have made a great deal about the security issues surrounding this product. It is true that without a cylinder lock AND something mounted on it, the carrier can easily be stolen. However, since my mountain bike has a through-axle fork, and thus requires a through-axle adapter, I simply leave the carrier locked against the through-axle adapter. Even if your bike fork is a quick release, I recommend buying a through-axle adapter to affix to the carrier when your bike is not on it. You can get one for $20 online. In my view, this completely resolves any security issues

    Rated3out of5byfromHassle preventing theftThis carrier works fine, as expected, and is easy to install. I bought it because it would fit over a Subaru Aero crossbar, which it does just fine. However, to lock the rack onto the crossbars, there needs to be tension in the skewer such as when there is a bike on top. To lock it when there is no bike on top, you need to screw down the adjustment on the far side of the skewer, then re-adjust it to get your bike back on. However, adjusting the tension is a two-handed operation, so its difficult to do it when holding the bike up with one hand. But, the bike needs to be there in order to get the tension right -- you see the problem. So, adjusting the tension is a pain, which isn't too bad if you have to do it once in a while, but I use both my car and bike for daily commuting which would mean that I'd need to adjust the tension each time I took the bike on and off (if there's no tension, then the rack can be completely removed, even if locked with a key). Finally, even if you are not concerned about the rack being stolen, you probably need to tighten it even without a bike just so the skewer doesn't spin and rattle around while driving (I suspect -- though I haven't tried driving with it loose). I've made my life easier regarding locking the rack by fashioning an open ring that is the width of the combined forks on the bike. When my bike isn't there, the ring goes on and it locks just fine. A few years ago I bought a carrier that had a lever that opened up both sides of the fork mount symmetrically and still have this one (though it doesn't fit on my current crossbars). This old one is much easier to use on a daily basis and I'm not so worried about theft of the carrier since tools would be required to remove it. I'd have preferred this old system, but didn't see it available. I wonder why it was discontinued.

    Rated4out of5byfromSturdy on an XSPORTER RackA great rack that actually fits a Thule XSPORTER Truck Rack really well right out of the box. And, you don't need an adapter kit - despite what the fit guide says. The Circuit comes with an assortment of bolts for the rear mount. The Circuit goes on and off my rack in minutes without tools. Can't ask for much more. At this price I wish it came with a lock core but I know it's standard to not include that these days.

    Rated5out of5byfromFork Mount CarrierCarrier fit easily on my Subaru. The carrier supplies secure (bought locks)storage for my road bike. I assume it will work for my mountain bike as well, but I haven't tried it yet.

    Rated4out of5byfromNice setup with a few peculiaritiesThis is Thule's simplest bike carrier, and as such is the lightest. However, all of the parts are very durable and relatively easy to adjust. Primarily designed for factory racks, a big plus is that this also works seamlessly with AeroBlades (or square) bars without the use of an adapter kit. Using adapter kits requires cutting AeroBlade rubber stripping, which makes removing the bike carrier challenging. It takes about 60 seconds to properly put on or take off this rack, which is very convenient in my mind. Wind noise is about average, and yes, it does affect gas mileage, but no more or less than any other aerodynamic rack. As others have noted, there are a few things one should be aware of with this rack. One, the skewer must be screwed all the way in if you want to keep the carrier on without a bike. It takes about 10 seconds to do this, but is a bit finicky because of the spring-loaded tensioner that wants to fight back. However, if you don't do this, the skewer will rattle around (and you wouldn't want to remove it since it locks the head of the rack down). Also, the "oversized" skewer head can create problems with suspension forks where the clearance between the dropout and fork leg is limited - when you close the quick release on the skewer, its slightly large shape and size places upward pressure on my MTB fork, meaning I have to pay close attention to making sure it's properly locked down (perhaps another fork mount adapter would help alleviate this). With my road bike, however, I have no problems at all. Finally, it is theoretically possible for others to unscrew and take the knobs holding the rack to the rear bar since they are not locked down. Not sure anyone would actually do this, but I guess it could be a problem if it happened. Point is, if someone wanted to vandalize any rack, they could do so, and the Circuit is no more or less susceptible. I would give it 4-1/2 stars if I could, and it would be 5 stars if a few of the little things above were addressed. Point is, this rack is very light, secure and adjustable, and comes at a great price point. Make sure you have lock cylinder for the skewer, and just take a few seconds to adjust it properly when using it with and without a bike, and you won't have any problems.

    Rated4out of5byfromGood rack at a good price pointThis carrier was well thought out to be useful on a variety of roof rack styles and only took about 5-10 minutes to install. The only complaint I would have on this product is that the locking mechanism and key should be included with it.

    Rated3out of5byfromIt looks nice but...In the past 15 years, I've gone through at least half a dozen different set ups, from Yakima to Thule, both roof and hitch systems. This roof bike rail is a solid piece that at first impressions, you would think would lead the Thule bike rail brigade. Where it has this aerodynamic front end that looks like a airplane front nose, it lacks security. And when you have a $6K to $8K bike on top, it makes you second guess as to how long you want to leave your bike up there. There is no way to lock this carrier to the cross bars. The front mount for the cross bars are a difficult to tighten single twister, and the rear mounts are two hand tightening plastic fobs. No locks to keep them from being easily just taken from prying eyes. As much as I like the brand of Thule, I think if you compare to Yakima, Rocky Mounts or other up coming designs--you can find something better designed.

    Rated3out of5byfromWell made - Security issuesTypical solid, well-made Thule product. Allows use of existing factory rack. Clean look and installation. Think twice though if security is an issue for you. Unless there is a bike attached or the skewer is screwed all the way in, it would be quite easy to steal this rack, even if locked. All one would need to do is unscrew the nut combo on the skewer. Also skewer rattles against rack if empty. It is a hassle to screw the skewer in and out constantly. Taking skewer out to stop the rattling also leaves it vulnerable to theft. Hopefully Thule will address this issue.
