Only negative it’s that the barrel adjuster looks cheap with a clip holding it in place rather than a sprung slider on other vastly more expensive options.
Hey Sam – mine arrived like that as well. Well, the first one arrived without one at all and I used one from an old rear mech instead. The other two I ordered from a different merchant arrived with a clip thing, and the barrel adjuster loose in the bag rather than screwed into the lever. The clip seems to be to hold the adjuster, screw and spring together on the lattter two levers. Pull the clip off – there may be a fully functioning spring under there.
That said, the screw part itself has too shallow a recess for the cable outer, which makes the outer wobble about when you push the lever. I really hate this, but it’s an easy enough fix if you have a friendly LBS happy to trade doughnuts or beer for a parts bin rummage.
