Our bikepacking setups rarely feel complete without our spacious seat packs in the rear to carry all our bulky stuff. Ditch the sweaty backpack and let the Exo-rail take care of your luggage.
Exo-rail is our unique system for adding stability and dropper seat post compatibility to your seat pack for minimal sway in your bikepacking setup, all the while reducing faff with its simple slide-on, slide-off pack attachment system. Convenient, light, and sturdy – it's ideal for tackling whatever the road, the track, or the trail throws at you...
The Exo-rail system fits to your saddle rails with minimum faff. The rail itself slots in with your saddle rails and clamps into place with the clamp and bolts provided. Once on it is unobtrusive and elegant, with no moving parts to clang around, so you can leave it on ready for when you need it.
The Exo-rail’s shape allows for multiple attachment options, depending on your pack, your frame, and your preference. Our Koala seat packs, available in 7 litre and 13 litre capacity, now feature a slide-on, slide-off Exo-rail sleeve that is incredibly simple to use and gives your seat pack setup excellent stability.
Will it fit my seat post?
Exo-Rail does not fit all seat posts.
It does fit 2 bolt micro-adjust seat posts with the bolts in line with the bike, including Rockshox Reverb dropper and all Alpkit seat posts. Exo-Rail does not work with single bolt seat posts or posts with side-by-side bolts. Watching the video will help you determine if your seat post head is compatible, but if you have any doubts please send us a link or a photo of your seat post so we can advise.

What a great solution to what is probably the biggest bag problem in bikepacking. Easy to fit, although an extra pair of hands helps. Gives a really solid anchor for strapping your seat pack in place. Ace product!
Does what it says on the tin
Bolted it in last night and took 2 minutes.
Now I personally hate tail bags, they sway all over the place unless you carry the weight of a tea towel.i went back to panniers but wanted a solution to the sway.
Now I use Blackburn bags for my sins so no sleeve. Works a treat. Just pull the back piece over the rail. Rock solid. Alternatively just wrap a bungie round it.
I ride fast and also heavy and I was amazed today how rigid and I also forgot it was on the bike.
Just buy it and try it.
Top kit! Versatile! Secure!
I bought the rail because I have a bag with a sleeve that the rail can fit into. The rail is solid, really versatile, secure. It takes the faff and guess work out of bag mounting.
Usual quality, beware the fitting!
This looks and feels like a great idea, I have the bag to fit and bought both ahead of a couple of upcoming bike-packing trips. Once on the bike everything feels sturdy. I was hopeful that I could fit to my cane creek thudbuster, but alas no, the thudbusters micro-adjust clamp interferes with the middle cast aluminium peice of the exo rail. Fits fine to my alternative seatpost, however this uses M5 bolts, smaller than the supplied extended bolts, so something to check before ordering as you will need longer bolts!!
Faff to mount
A pain to mount, but once it's on, really helps stabilize the bag. I will use it with my taper Airlok. Only good for 2.3kg but that will work for me. Using my measuring calipers, it adds 8mm to your seat height. It would be good to mention that in the instructions.
Narrow saddle rail
Exo-Rail plate (and the rails) only have circa 42.7mm spacing. My Nitto S83 seatpost and Selle Italia saddle both have a 44mm rail width which has long been the industry standard. I like the system and if the plate was wider would have fit the Nitto S83 fine. If the plate (and Exo-Rail) came in a 44mm spacing, I would buy it again without hesitation. Odd that that this narrower spacing was chosen.
