Reverse Collier Jeu De Direction 1 1/8″

The ” STEERER CLAMP” Spacer is a headset spacer with an additional clamping function!
This is placed instead of the normal 10mm spacer under the stem. It creates additional clamping forces to avoid “loose” headsets! It’s also super useful when you’re working on your bike.

Let’s say you have your bike in an assembly stand and you want to remove the stem and handlebars.
The spacer will still hold everything in place even without the stem and the fork can’t fall out. It is also very useful when you are on the road. Namely, if you put your bike with other bikes in the back of a car / van and have to twist the handlebars for transport. Everything remains secured and the headset is not loose. Optimal also for air travel when you have to pack your bike in a bike case.
