Loobman Chain Oiler - I took a bit of a punt with this chain oiler for a few reasons. The first was the price (around 20 if I recall correctly) - it was one of the cheapest on the market. The second was that it used standard engine oil, which I was planning to carry a supply of anyway. So it made sense. The oil is primed by a spring loaded plunger, and then gravity fed onto the rear sprocket via a couple of cable ties mounted in a bespoke holder. It was also relatively easy to fit and easy to use... for the first few thousand kms. It then started to get its feeder holder bogged down with a mix of oil and road dust/sand which prevented the oil feeding correctly onto the sprocket. This required more fiddly cleaning to keep the oil feeder clean and operational... which got to me after a while. By the time I arrived in Lima, Peru (where I was changing out the chain and spocket) I had decided to dump the thing, and revert to a can of chain oiler, as it was easier to spray the chain than have to keep adjusting and cleaning the feeder cable ties. To be fair most riding in the UK and rest of the EU (where the product was designed) would not see the level of dust and sand I encountered - and for UK style riding I would seriously consider it again. But for overlanding, I would look around for a similar product using engine oil, but depositing it through a simpler feeder direct onto the inside of the chain. Not Recommended (for overland use).
