Goo quality product. No complaints
Verified Purchase
Very pleased with this product again.
The stem works well but you will need to get a spacer because the stem is not as tall as the original. Mine needed a 2mm. thick spacer to get the proper head/ bearing preload. After that it was just fine. Quality of the product was good. If I need another ,I would not hesitate to order this one again.
