Extralite Hyper stem. This fits a 1 1/4 inch steerer tube. Not the more common 1 1/8 inch.
100mm length -6 degree.
It’s in excellent condition. Hardly used. I realised I needed a shorter one after a couple of rides so replaced it. It’s been sat in its original packing ever since.
Great stem. Unbelievably light. I used this stem on my gravel bike and cyclo bike. It’s plenty strong/stiff enough for me. I only weigh 68kg though. The one on my cx bikes has survived numerous crashes no bother.
