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.

Lumpa is a nifty harness that makes earlier versions of the Koala seat pack (and other seat packs) compatible with our Exo-Rail anti-sway mounting system. Pair up your Koala with the Lumpa and #LoveYourGearForLonger.

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 strap in bits and bobs like inner tubes or flip flops – and it doubles up as a mud guard.

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, there buckles will no be compatible with the buckles on your Koala.
