Excellent product
"I had shimano dura-ace levers in 9v, ultegra 10v and the original sheaths suited me just fine. I installed 11v levers in shimano 105, and I was not satisfied with the operation, very far from the previous excellent quality. That's why, after only 6 months, I installed this product: The result is incredible: I've got all the smoothness of the levers back, and the shifting is much improved. It's expensive, but it's really worth it."
