I’m building up a shigura setup with XT M8100 levers and mt5 calipers using the magura hose. I’m getting a leak at the lever and the olive looks mashed.

The levers didn’t come with nut or olive so I’ve bought generic pack of lifeline BH59 nuts, barbs and olives. The magura barb seems to have a much bigger shoulder than the shimano ones and the olive compressed on that the first tine. A shimano barb will go in the magura hose fine and the hose seems far enough in judging by where the olive sits, its just wonky. The chamfer on the generic nut looks pretty small, so I’ve ordered some genuine bh90 kits.

Anyone had this before?

that olive looks terrible.

Why not use a shimano olive at the shimano end and a Magura olive at the magura end?

That is a (generic) shimano olive, barb and nut at the shimano end, magura hose.

Generic? Not genuine Shimano…?

Wiggles finest, got some genuine shimano on order as per the op. Just wondering if anyone has seen it before.

There are two different Shimano barbs, not sure about olives. If you have mashed oe badly, make sure you root around in there with a pick to get any shards out that may still be in there.

The last time I did a hose barb and olive job, the olive would not slide back up onto the hose around the barb. I had to clamp a small spanner to my workmate, then tap the barb end of the hose with a pin hammer to get it to go. It was a pain in the arse.

Genuine shimano nuts and olive worked first time, no leaks at the lever.

Let that be a lesson to you! Cheapest isn’t always best? Pleased you’re sorted.

Well in this case it was a case of less haste more speed, as the wiggle delivery was quick (hence the gamble), the subsequent wait for genuine parts felt like aeons.

Sounds more like a case using the right barb. BH59 and BH90 are different. Was the barb that worked silver or gold coloured?

I used the knock off BH59 barbs as the id of the Magura hose is between shimano sizes with a BH90 nut and olive (same dimensions as the knock off BH59 nut and olive – apart from the chamfer).
