Inno Fork Lock III on roof

The Inno Fork Lock III fork-mount carrier lets you transport 1 bike on the roof of your vehicle. A 9-mm quick-release skewer secures your bike's front fork, and a ratcheting strap holds the rear tire. The carrier clamps onto most crossbars with no tools required. A locking cover secures your bike to the carrier and the carrier to your crossbars.

Fork Block with 9-mm Skewer

Inno Fork Lock III with skewer openInno Fork Lock III with skewer closed

The fork block includes a 9-mm quick-release skewer with an oversize handle. To mount your bike, simply open the handle, lower your bike fork into the skewer, tighten the adjuster, and close the handle. The adjuster will spin freely once your skewer is secure to prevent over-tightening.

Adjustable Rear-Wheel Strap

Inno Fork Lock III rear wheel strap

A v-shaped wheel tray holds tires up to 2-11/16" wide. The rear wheel is secured by a strap that slides along the tray to accommodate bikes of different lengths. The strap ratchets down on both sides of the rear tire to ensure a tight fit.

Easy Installation

The rack installs easily with included mounting hardware - no tools required. Just open the front cover and lift the front lever so you can remove the square nut from the mounting bracket.

Inno Fork Lock III front lock closed

Place the rack on your crossbar, slide the bolt into the open end of the bracket, and secure it in place with the square nut. Use the 2 hand knobs and the square nut to adjust the bracket to the size of the crossbar, then close the lever to tighten.

Inno Fork Lock III rear bracket

The rear mounting bracket secures to your crossbar with 2 bolts and 2 knobs. Simply place the bracket under the crossbar, slide the bolt into the bracket, and tighten with a hand knob.

Depending on the thickness of the crossbar, you may need to use the included spacer or rubber sheets to mount the rear hardware. Additionally, you will need the Inno long bolt kit (INISF725) to mount the rack on crossbars 1-1/8" - 2" thick.

Complete Security

This bike rack is a cheaper option to many roof top bike racks that can exceed $200. The system is very rigged and I have loved the system so far. I live around very rough roads, and I have not had the skewer loosen up at all. Even if it did, I feel much better knowing that there is a locking plat over the skewer. With the plate cover being plastic, I still run a bike lock through my frame and roof bar just to add an extra line of defense when camping/leaving my vehicle for extended periods of time. For driving security, the cover does exactly what is intended to do. Overall, a fantastic system and I enjoyed the first class customer service I received when ordering the bike rack. 500954

Had to really search for a roof-mounted fork rack for my Envoy with factory roof racks. Thule & Yakima do not make anything compatible withoutbuying their over-priced roof racks. I heard about Inno, and etrailer had the best price. I was still nervous when I received the rack, but install was straight forward and took about 15 mins. I centered the Inno rack on the vehicle because the factory racks are curved vertically. Fast communication & shipping from etrailer! 757119

I am very satisfied with my product that I ordered from you guys ! 756424

Works as advertised. No problems or complaints. No wind noise at all. Makes transporting bikes much easier! 654300

This matches the previously purchased item. Great rack! 617405

This rack is great. Seems strong and fits my Gary Fisher Mullet easily. Easy to set up. Best thing is Etrailers shipping and tracking. Literally shipped the night I ordered it. Etrailer is great and I would have no reservations about ordering from them. 605442

Easy to install and works great with my Gary Fisher mountain bike. Plenty of clearance for the brake caliper! Used it in combination with my Rola roof rack on my 2013 Hyundai Elantra. Paula was a huge help with both my orders and making sure I got the right product for my vehicle! Excellent customer service! 522999

Product was very easy to install , very sturdy and well thought out rack. Great service form etrailer keep it up, would definitely recomment to my friends. Happy camper here. Cheers! 508448

- INA391

Good product with one exception> Works great on road bike forks but does not support moutian bike forks. You can buy and us an adapter but then you lose the ridgidness and the ability to lock the bike through the fork mount. 460051

- INA391

Ordered this bike rack for my wife's van. They said it would take 3 days for delivery got it in two days. Set up was easy. It took me longer to get the rack out of the box than it did to get it installed on the roof. Had to make small adjustment to get the bike to sit just right but it was easy. I have had all kinds of roof mounted bike racks in the past and I have to say this is with out question the easiest install and best looking rack I have used. It also has the best locking set up I have seen. No worries of someone staling it off your roof. 417070

Great product, easy and quick to setup, very stable. Delivery was on time as promised. I have using this Inno Fork Lock system for about a year now and like it a lot. Many thanks for etrailer.com team to create and manage website! Your videos really helped me to choose the right product. Keep up a good work and thanks, 401217

After two years of use I can confirm that that was the right purchase for us. No complains so far. Easy to put it on and take it off. Works for both mountain and road bikes. Steady and tight on the roof rack of my Ford Fusion. I would recommend this product to my friends. Thanks to Etrailer staff for keep doing great job!

Installed in about 5 minutes on my 2015 Honda Pilot factory crossbars and worked well on first use with a mountain bike. No noticeable wind noise when no bike is loaded. 266542

- INA391

Great rooftop fork mount bike rack that seems like it will attach to just about any bar system or factory rack. Simple enough to install, seems durable and secure, with one minor drawback. The strap for the rear wheel is a rubber "pull to tighten" instead of a ski boot style clamp. I imagine this as difficult after those winter rides with frozen rubber and fingers... But working well in the summer. 209212

  • Recommended Adapter for Fork Mounted Bike Carrier to Hold 15mm Thru-Axle Forks
    I was able to find your order of the Inno Fork Lock III Roof Bike Rack - Fork Mount - Clamp On - Aluminum # INA391. I reached out to my contact at Inno and he said they don't make an adapter but other manufacturers do that are compatible. I recommend the Yakima Universal Fork Adapter for 15-mm, Thru Axle Forks # Y02099, the Thule # TH53015, or the Swagman # S64706. All of these will be compatible, so it comes down to brand preference.

  • Availability of Class II Trailer Hitch for 2000 Honda Accord EX to Carry 4 Bikes
    Since there are only Class I hitches available for your 2000 Honda Accord you're going to be limited to carrying 2 bikes using the trailer hitch method, even if you were to try using an adapter. If there was a Class II hitch available I would still advise against going this route because a hitch adapter will reduce your weight capacity by 50%. For your application I recommend using the Rhino-Rack Vortex roof rack system with a roof mount bike rack like the Inno Fork Lock III # INA391....

  • Crossbar System and Bike Rack for RetraxONE XR Hard Tonneau Cover on 2019 Ford F-150
    For the crossbar system that works perfectly with the RetraxONE XR Hard Tonneau Cover # RTT-60373 on your 2019 Ford F-150 I recommend the Yakima CoreBar System # Y00422-482104. This includes the two 60" aerodynamic CoreBar crossbars, the 4 Skyline towers that get mounted to the integrated channels on your tonneau cover, and the custom Landing Pads that are designed specifically for those tracks and can remain mounted even when you remove the rack and are using the cover. This system...

  • Adapter Needed to Fit Thule Prologue Pack 515 Bike Rack to Rhino-Rack Vortex Crossbars
    Thank you for the details and the picture! Since you have everything to mount your (discontinued) Thule Prologue Pack 515 to the square bars all you need is the Thule Ride-On Adapter # TH532 to mount this bike rack to your Rhino-Rack Vortex crossbars. The only problem is that this adapter is the only thing available for a Prologue Pack bike rack and it is only able to accommodate 2 bikes. So if you only need to transport 2 bikes then you will be all set. Otherwise you need a new bike...

  • How to Transport 5 Bikes on 2008 VW Passat Wagon with Class I Trailer Hitch
    You are correct that a light-duty 1-1/4-inch Class I hitch like # 24848 has a 200-lb tongue weight (TW) capacity. However, when it comes to bike racks there is another factor that comes into play, leverage on the hitch tube. The more bikes the rack holds the longer it tends to be, naturally. This increased distance from the hitch to the outermost bike translates into extreme leverage forces on the hitch tube, forces that would damage a light-duty Class I hitch. For this reason all Class...

  • Can 2017 Subaru Outback With Class 1 Hitch Carry 3 Bikes
    While there are ways to carry 3 bikes on your 2017 Subaru Outback, a class 1 trailer hitch is limited to carrying just two bikes due to the amount of weight and torque put on the hitch for a rack that extends out that far. The easiest - and least costly - way to do this is by forgoing your hitch to carry your bikes and going with a trunk-mounted 3-bike rack, the Thule Gateway Pro 3-Bike Rack # TH78VR or Yakima FullBack 3-Bike Rack # Y02633. This will give you a safe, secure, and...

  • Best Way to Carry Bikes on a 2016 Mini Countryman
    There are two Yakima racks (The Halfback, # Y02636, and Fullback # Y02634) that are confirmed to fit your 2016 Mini Countryman. However, they both need to be converted to anchor mode which can cause damage to the headliner of your Mini over a period time. So if you're not gonig to be carrying your bikes very far or very often they are good options. If you will be carrying them longer the Hollywood Racks Over-the-Top carriers are a better option. Both the 2-bike, # HRF2 and 3-bike,...

  • How Does the SportRack Downshift Plus # SR4624 Lock to Vehicle Crossbars
    The SportRack Downshift Plus # SR4624 has the ability to lock the bike to the rack, but not the rack to the vehicle crossbars. To do that you would have to loop a cable lock # e98891 through your bike and around the crossbars on your vehicle. If you want bike rack and bike locks out of a roof mount bike rack then we have some other options for you. For a similar aluminum bike rack we have the Inno Fork Lock III # INA391.

  • Does the Swagman Upright Roof Bike Carrier # S64720 Lock to Crossbars
    Many bike roof mounted bike racks do indeed have locks to secure them to a roof rack, but the Swagman Upright Roof Bike Carrier you referenced is not one of them. The most reasonably priced rack we offer that is compatible with the Thule AeroBlade crossbars that can lock the bike and lock to the crossbars would be the Inno Fork Lock III Bike Carrier # INA391. This is a fork mount rack, so the bike would need quick-release front hubs. I have attached a review video of the Inno Fork...

  • Bike and Kayak Carrier for Inno Rack on 2010 Dodge Caliber
    The Inno roof rack that fits your 2010 Dodge Caliber uses 50" square crossbars # INB127 which are 7/8" tall x 1-1/4" wide, although your vehicle also has a crossbar spread of 20" and kayak carriers generally need a minimum spread of 24". Due to that I recommend using the Yakima Crossbar Pads # Y07415 to carry your kayak; these are 30" long pads and to secure your kayak the Quick Draw Tie-Down Ropes # TH855XT and Cinch Straps # TH521. For a bike rack I recommend checking out the Inno...

  • Recommendations For Carrying 3 Bikes And A Trike On 2010 Mazda CX-9
    The trailer hitch I recommend for your CX-9 is the Curt Trailer Hitch, part # 13575. This is a Class lll hitch and it has a 2 inch receiver opening. I have attached a link to an installation video for this hitch on a 2010 CX-9 you can check out. Carrying 3 standard and one 3-wheel trike is going to be difficult. Although costly, I recommend a hitch-mounted carrier like the Hollywood Racks Sport Rider SE2 Trike Carrier, part # HR1450Z-E-TRKADP3. This will carry the trike and one additional...
