Inno Slim Fork with bike

The Inno Slim Fork lets you transport 1 road bike or cyclo-cross bike on the roof of your vehicle. A 9-mm quick-release skewer secures your bike's front fork, and a ratcheting clamp holds the rear wheel. 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 Slim Fork with 9-mm skewer openInno Slim Fork with 9-mm 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's front-wheel fork onto the skewer, tighten the adjuster, and close the handle. The adjuster will spin freely once your skewer is secure to prevent over-tightening.

Sliding Rear-Wheel Cradle

Inno Slim Fork sliding rear cradle

The Slim Fork has a sliding cradle that grips your bike's rear wheel. The cradle tightens with a ratcheting hand knob, and it holds all rim heights including the tall rims found on road bikes and cyclo-cross bikes. The cradle adjusts along the body of the rack to accommodate bikes of different lengths.

Inno Slim Fork rear tire strap

A hook-and-loop strap is included for additional rear-wheel security when you are driving on rough roads or when the cradle isn't grabbing the wheel tightly. To install, run the strap between the spokes of your wheel and wrap it around the body of the rack.

Easy Installation

Inno Slim Fork front clamp

The rack is simple to install and requires no tools. It easily clamps onto most crossbars with included mounting hardware. Cam levers tighten the clamps in place. To install on your front crossbar, lift the cam-action lever on top of the fork block and remove the square nut from the mounting plate. Position the plate under your crossbar and slide the square nut and bolt back into the plate cutout. Tighten the square nut and then close the handle to secure it in place.

Inno Slim Fork rear clamps

To mount to your rear crossbar, open the lower cam-action lever and slide the bolt out of the lower bracket. Place the lower bracket under the crossbar and slide the bolt back into place in the bracket. Tighten the lower lever until the carrier is secure.

Inno Slim Fork spacer diagram

A spacer is included for use with crossbars less than 1" tall. Rubber sheets keep the spacer from touching the crossbar.

The Slim Fork can be mounted on either side of your vehicle. Just make sure the quick-release skewer handle and the rear-wheel cradle knob are facing the side of the vehicle from which you want to load the bike.

Complete Security

Inno Slim Fork locking cover

The Slim Fork's fork block has a locking cover that lets you secure your bike to the rack and your rack to the crossbars. The quick-release skewer handle is under the cover when closed and it cannot be opened unless the cover is unlocked. The front mounting hardware is also under the cover so when the cover is locked the rack cannot be removed from your crossbars.

Overall this is a sturdy rack of good quality materials. However, if the distance between your roof top and the bottom of your crossbars is less than 2.5 inches, then the lever lock device on the rear tire holder cannot be engaged. This needs a redesign to accommodate narrower distances. You can eliminate the lever and make it work, just not as designed, so 4 stars. 909715

First off Kaylyn was amazing great customer service I told her what I needed and the rack she suggested is perfect! The racked shipped to me in only a few days. I have a 2019 Toyota C-HR with factory crossbars. Easy to install and I used it for the first time, drove 90 miles with my bike on the roof rack and no problems. I’m am a repeat customer etrailer is a great company. 634211

I have always used Thule equipment to carry my bicycles, kayak, etc. but my Honda CRV has factory roof racks which don't work well with the Thule system. The mounting system on the Inno rack is more flexible and works well with the OEM rails. Mounting the Inno on the roof racks is a straightforward process. I found the front part to mount quickly and easily while the rear mount needs more room to operate the mount properly. The rack securely holds bicycles and the rear "clamp" system is pretty nifty. The front mount for the fork rack is okay but I do miss the elegance of the Thule design. Overall, it gets the job done. 286113

  • Does Inno Slim Fork Roof Bike Rack Fit Road Bikes and Mountain Bikes
    As long as both of your bikes have 9-mm quick release skewers the Inno Slim Fork Roof Bike Rack # INA387 that you referenced will fit and work well with both of them. As long as your crossbars are less than 3-1/2 inches wide and 1-1/4 inches tall on your 2015 Subaru Crosstrek this will fit in that regard as well.

  • Parts Needed to Carry Kayaks and Bikes Above Bed of 2014 Ford F-150
    For a ladder rack system that will allow you to easily carry your kayaks and bikes above the bed of your 2014 Ford F-150, I recommend the Rola Haul-Your-Might Truck Bed Ladder Rack - Aluminum - 400 lbs, part # 59742. The crossbars are plenty long, at 63", and feature universal T-slots on top for attaching channel-mounted accessories. To maximize the crossbar space, I recommend a post-style kayak carrier, like the Yakima BigStack # Y04041, which lets you carry two kayaks on their sides...

  • Bike Rack Solution for 2015 Audi S3
    I wish we had a hitch for your vehicle, but at this time none of our manufacturers have any fits for the 2015 Audi S3. You could install the Inno roof rack part numbers # INB127, # INSUT, and # INK877 so that you could use a roof rack bike rack like the Inno Slim Fork part # INA387.

  • Inno Square Bar Roof Rack for 2003 Mercury Mountaineer
    In order to get the longer bars, you'd order the parts separately. You'd need the roof rack feet, part # INFR and the # INB147. There won't be a cost difference by ordering the feet and crossbars separately. Inno also offers quite a few accessories that are compatible with the rack. A fairing like # INA260 would make the rack more aerodynamic, reducing the wind noise. For a rack mounted bike rack, take a look at # INA387 fork-mount rack. For a kayak carrier, check out # INA452.

  • Which Roof Bike Rack for Use on a Yakima Roof Rack on a 2010 Honda Odyssey
    Your choice of a roof-rack-mount bike carrier will depend on which type of crossbars you have since some will not fit the elliptical types but virtually all will fit on round crossbars. The Yakima roof racks we offer for your 2010 Honda Odyssey use crossbars of both the round and the more aerodynamic elliptical types. Also, there are three general types of roof bike carriers: fork-mount, frame-mount and wheel-mount. These differ in where they hold the bike to secure it to your roof rack....

  • Could Sportrack Upshift Bike Rack SR4883 Fit with Roof Basket Installed on Vehicle
    The overall width of the SportRack Upshift Roof Bike Rack # SR4883 that you referenced is 8 inches. If you have 8 inches of crossbar space available this would work well. Since you didn't mention whether the 48 inches of your basket is the width of how long your crossbars are it's hard to say beyond that.
