2014 Nissan Frontier

Cheap alternative compared to having to buy a 9mm thru axle mount for the utili-track in my Nissan Frontier AND THEN having to buy an adapter for that! For under $10 I bought some parts from a local hardware store and made this mount fit the track. It's sturdy, and high quality.

Im still using it and it still works great. Thank you.


Disappointed. The Kuat Dirtbag works, and feels relatively solid once installed, but is about 2-3 mm shorter than my hub. That means while loading and unloading the fork doesn't sit nicely on the rack and inserting/removing the thru-axle can be quite challenging. I'd heard great things about Kuat's products, and all I can say is I'm glad this one isn't as overpriced as the rest of their lineup.


My Kuat DirtBag Bike Rack Application

Nice product



Product working as well as the first day. No problems after 1 year


This is perfect for custom applications. I used this mount on a piece of plywood that fits in the back of my SUV. Simple, basic, exactly what I was after.



Its been through a year of use, 4 times a week average, holding up great and performing like new. Total satisfaction!


Easy. I made the coolest rack ever. I didn't want to drop $300 and have the the bikes so high up on the roof. I came across these and enough said. best ever. My 1978 VW couldn't be cooler. All my Bus friends are jealous. They dropped the $300-ish, and now want my rack. My son and I bike throughout CO. too cool.

Thank you for the product and excellent service.

Rocket Rich

Rocket R.


We still have the coolest VW bike rack!!


I use this in the back of my truck to hold my mountain bike. See attached photo. Works great. Paint starting to chip off around the screw holes. Not a big deal.


I used a few of these fork mount options to build a truck bed bike rack. They've been excellent and were easy to work with(also budget friendly.)

I found that the 100mm width worked well with some 3-d printed adapters I made to fit wider forks as well(that way I have more flexibility.)

Would highly recommend.


The bike rack was exactly as represented. We can now carry mountain bikes with the thru-axle setup easily and securely. The service was excellent and delivery was prompt. We need to buy a trailer hitch for another bike rack and will certainly use etrailer again.

2013 Ram 1500

The product was great. but the service was even greater! 2 days (and a 4th of July holiday) before transporting my expensive bikes in the bed of my truck, I realized my homemade rig wasn't going to cut it. Panic! I got online with etrailer and found a part I wanted at 7PM, but needed overnight delivery. Whew, I got the order in. But, oh wait - I get an email 10 minutes later that the part I asked for was backordered. Panic ^2. But the email from eTrailer said call us NOW and we have a possible solution. Yeah, right. So I call, and - they did! Talked to real humans and they set me up with a substitute part that did the job and I had it on my truck next day. Totally awesome. Real people rock. Thanks to eTrailer, I had my bikes with me in Idaho and Oregon and Washington where I had to play my music gigs. Love you guys, and thanks for being real people!

Ford F-250 Super Duty

Works great. I have a F-250 with a tool box in the bed. My axle racks are mount on the tool box lid. Well make.

Rating - Excellent

Toyota 4Runner

Great product for the price. I bolted the mount to a 2x4 using carriage bolts. Using the rig to haul my mountain bike inside my 4Runner. Using friction tie-downs in combination with the fork mount. Solid.


The DRT15 works great for my through axle mountain bike. I mounted it to a plank, along with my other fork mounting systems, and can easily get the fork on the unit and axle reinserted in no time. Solidly built and well engineered.

2017 Pontiac Trans Sport Van

I am using this as a base for an interior rack in my Jeep Renegade. This will be mounted to a 2x3 section of fiber board that will fit flat in the rear of the Renegade. The bike fork fits perfectly and this will be a great way to transport my bike safely and securely. The service from etrailer was great too with prompt order delivery and great packaging. I will use etrailer again in the future.


simple and effective, and does what it's supposed to; that's all anything should be. I screwed it to the front top of my truck bed using self tapping screws.

Pontiac Trans Sport Van

Perfect size. Ordered simular item from Amazon and the size was not correct. etrailer shipped the correct item on the first try. A sturdy way to transport thru-axel mountain bikes.

2002 Ford F-350 Super Duty

Product is great and will work and was a great price!


works, have buy mounting board bolts and etc. Had to add 5/8 washes to pace it out to 115mm fork. no options there.


Exactly what I needed. Price was great. This bike holder works great on my 29" mountain bike. Shipping was fast.

2015 Pontiac Trans Sport Van

Product is sturdy and works well for bike transport in back on my van. Service was very fast. Certainly would use etrailer again when needed


This fork mount is the perfect way to anchor my bike in my truck! Works great!


Rack mounts are what I expected. Vince at etrailer was super helpful. I would order from them again!


Product works well, as advertised. Holds bike securely.



Yes I still like the product. It works well and is quality made. Thank you,

Subaru Baja

I originally ordered wrong hub size, my fault. A quick rerun and no issues. Mounted on a 2x4 and placed in the back of my Subaru Baja. Flawless!


The finish on it is perfect !!! After one year in sun rain and snow it look new !!! Hold very tight and sturdy !!! Will buy again for sure


Very well designed and quality construction extremely happy with it. Price was very reasonable and shipping was quick.

  • Will Trek Remedy 7 650b/27.5 Bike Fit Kuat Truck Bed Bike Rack # DRT15
    Yes, your Trek Remedy with 15mm front wheel skewer will fit the Kuat Truck Bed Bike Rack # DRT15 as long as it has a thru-axle type skewer. This rack works with bikes with standard or disc brakes. Please note installation hardware is not included; 1/4-inch or 6mm diameter hardware is recommended. The skewer sleeve length is 100mm so as long as your skewer is not larger than this it will fit your bike.

  • Dimensions of the Kuat Dirt Bag part # DRT15

  • Will the Kuat Dirtbag Mount A Trek Powerfly 5
    The Kuat Dirtbag Bike Rack # DRT15 requires a 15mm x 100mm axle size. Per the Trek site, the front hub through axle is 15mm on the Powerfly 5 so this will work great for you. From here you would just need to arrange the mounting location and obtain the mounting hardware needed. The video provides some additional details to get you started.

  • Will a Dirtbag Phat 15 Fat Bike Rack Fit a Salsa Beargrease with 15 x 142 mm Thru-Axle
    Based on the measurements you provided on your Salsa Beargrease with 15 x 142 mm thru-axle, the Kuat Dirtbag Phat 15 fat bike rack # DRT15P will be a fit. The Dirtbag # DRT15P fork block works with fat bike forks that have 15-mm, thru-axle skewers. The base has 2 holes for easy installation too. I have included a video review for you too.

  • Kuat Dirtbag Fork Mount For Bikes With 15mm Thru-Axle Front Wheel Skewers
    I know exactly what is going on. That is actually the old part number which is now "inactive". The new part number is Kuat Dirtbag Phat 15 Fat Bike Rack - Fork Mount - Bolt On # DRT15P. This works with bikes that have 15-mm, thru-axle front wheel skewers. The sleeve length is 142mm. I attached a demonstration video for you to check out.

  • Recommended Truck Bed Bike Rack for Fat Bike on 2019 Ram 1500
    We have exactly what you need to carry a fat bike in the bed of your 2019 Ram 1500, the Kuat Dirtbag Phat 9 Fat Bike Rack # DRT9P or the Kuat Dirtbag Phat 15 Fat Bike Rack # DRT15P. The Phat 9 Fat Bike Rack # DRT9P will work with fat bikes that have 9-mm, quick-release front wheel skewers while the Phat 15 Fat Bike Rack # DRT15P is for fat bikes that have 15-mm, thru-axle front wheel skewers. These are the best options because they are a far more economical option than a roof rack and...

  • Does Kuat Dirtbag Bike Rack For 15 mm Thru-Axle Skewer Fit Saris Triple Track System
    I believe you are referring to the Saris Triple Track System # SATRK34, and yes, you can absolutely use the Kuat Dirtbag bike rack you mentioned: - Kuat Dirtbag Bike Rack - Fork Mount - Bolt On - 15 mm Thru-Axle Skewer # DRT15 The Dirtbag will fit this track system without issue so you can use it to carry your bike!

  • Will the Saris Traps Fork-Block Bike Carrier Base Part # SATRK33 Accept Other Racks
    The Saris Traps Fork-Block Bike Carrier Base part # SATRK33 and the Kuat Dirtbag Bike Rack part # DRT15 have not been tested to work with one another as they are two different brands. However, after reviewing both the rack and board it does appear they will work as the rack designed for the board is very similar to the Dirtbag. Again they have not been tested together so I cannot confirm fitment but the chances are high that they will.

  • Fork Mounted Bike Rack for 15 mm Thru Axle Yeti SB5c
    From the research I did it looks like the Fox 34 Fload forks you have on your 2015 Yeti SB5c (nice bike BTW), use a 15 mm thru axle. The # SATRK33 would not work with the 15 mm axles, it only works with 9 mm axles. The closest thing to this rack that I could recommend would be to use the part # DRT15 mounted on a board so that you could store your bike(s) in the back of your SUV.

  • Best Truck Bed Bike Carrier for Fat Bikes
    I do have a couple of options for you but The Swagman Pick-Up Truck-Bed Mounted 2-Bike Carrier # S64702 will not fit your Trek Farley Fat Bike. The Kuat Dirtbag Phat 9 # DRT9P and the Kuat Dirtbag Phat 15 # DRT15P are going to be your two options. They are both a fork mount bike rack that bolt onto your 2012 Ram 1500. The difference between the two is going to be the size of the skewer. The Phat 9 fits the 9-mm quick-release skewer where the Phat 15 will fit the 15-mm skewer.

  • Truck Bed Fork Bike Rack that Fits Bike with Boost 110 Axle
    I have a solution but the # DRT15P won't fit with your Boost 110 axle size. Instead you'd want the # S64703 with the adapter # S64719 and you'd be set.

  • Truck Bed Bike Rack Recommendation for Norco Bigfoot Bike
    Due to the very large tires and forks on your Norco Bigfoot the truck bed bike rack I recommend is the Topline 2 Bike Carrier part # UG2500 which attaches to the bed rail and then grabs the bike by the top tube to secure it in the bed. This alleviates the challenge of trying to find a fork mount that fits your larger setup and gives you a really nice rack for securing your bikes so it is an overall really great option.

  • Mounting Bike with Boost 110 Thru-Axle Fork to Truck Bed
    You might be able to bolt the Kuat Dirtbag Fork Mount # DRT15X110 to your Swagman 2 Bike Carrier # S64702 but I really can't recommend doing this. This would require drilling into the crossbar on the Swagman carrier which might affect its integrity and will also void the rack's warranty. You could certainly use the Kuat Dirtbag by itself by simply mounting it to a flat surface in the truck bed. You can use the raised bed rail up against the cab to create a similar setup as the Swagman...

  • Fork Mount for 12x100mm Thru Axle on Canyon Endurance CF SL 8.0
    I have a solution for you, but the # DRT15x110 will not work because it is for Boost axles. Instead I recommend using the SeaSucker HUSKE Bike Rack - Fork Mount - 12-mm x 100-mm Thru-Axle # 298-BA14203 which will fit the axle on your Canyon Endurance CF SL 8.0 with 12 x 100mm thru axle. The SeaSucker HUSKE mounts to any flat surface and comes with the mounting hardware needed to install this fork mount.

  • Can Bike with Thru Axles be used on Thule BedRider Truck Bed Bike Rack
    Thule actually makes a Thru axle adapter for the Thule BedRider part # TH822XTR that you have with the part number # TH535SKR. The base of the Dirtbag part # DRT15 measures 1-3/4 inches by 4-5/16 inches and should not be modified or installed in any way onto your BedRider.

  • Locking Truck Bed Rack For 12mm Through Axle Bike
    We do have a rack that will work with your 12mm thru axle bike but the Thule Bed Rider # TH822XTR isn't the best option for you. I would get the Swagman Patrol 2 # S64701 and then the 12 mm Thru-Axle Adapter # S64718. This set up will lock your bikes keeping them secure. I like these type of racks because you can remove it from the bed whenever you're not using it unlike bolt on racks like the Kuat DirtBag # DRT15. I've included a video to show you the Patrol 2 in action!
