It is a cover to cover when the W lever pedestal of the down tube is not used.
Mr. Blue Lug made a shape that matches well with the cable adjuster (outer stopper) of Shimano and diamond competition.
Nowadays, the number of car bodies assembled with a front single is increasing, and by attaching it to the other W lever pedestal without attaching a W lever or cable adjuster, the pedestal is not exposed or a useless adjuster is not attached. It can be assembled neatly.
Of course, when assembling at single speed, you can attach it to both the left and right sides ◎
It is a very practical item because it can prevent rust as well as appearance.
Since this DOWNTUBE SHIFT BOSS COVER has a glossy plating finish, the surface texture is different from Shimano's outer stopper (SM-CS50), but by lightly polishing it with a metal compound etc., it will not feel strange. You can use it.
* Since we are considering operation with a front single, we sell one on each side.
* Mounting bolts of the same color as the main body are included.
