Lumpa And Exo-Rail Bundle

We love new gear (who doesn’t?) but there’s a certain pleasure to be found in bringing the kit you already have up to speed with new technologies.

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. If you have a Koala, you can still reap the rewards of the Exo-Rail by pairing it up with Lumpa.

Lumpa is a nifty harness that makes earlier versions of the Koala seat pack compatible with our Exo-Rail anti-sway mounting system.

For smaller seat packs, this means they’ll be dropper seat post compatible. For larger seat packs, the stability of the Exo-Rail hugely enhances handling by reducing sway when on technical terrain.

When you’re not using a seat pack with the Lumpa, you can leave it on the Exo-Rail and strap in bits and bobs like inner tubes or flip flops.

Like all our UK made bike luggage, Lumpa is backed up by a 25 year Alpine Bond Guarantee.

Will it fit my seat pack?

Lumpa uses 20 mm Duraflex Buckles with Camlok, if you have a Koala from before 2015, their buckles will not be compatible with the buckles on your Koala.

Will it fit my seat post?

Exo-Rail fits 2 bolt micro-adjust seat posts. Watching the video will help you determine if your seat post head is compatible, but if you have any doubts whether Exo-Rail will fit your seat post, please get in touch with a link to or a photo of your seat post so we can advise.
