General information about our shipping
Installed rear mech and aesthetically its absolutely beautiful. It's light but the materials are noticeably durable. It shifts terrifically, smooth with a glide.
- Significant improvement over my previous 105 system - Cables need a break-in period to take out elongation - Precise shifting, some adaptation is needed as the shifting is really soft and silent (which is good!) but you wonder sometimes if it effectively happened or not - No problems with installation.
Shimano's flag ship, light, efficient and great finish.
Dura Ace has been the leading brand for centuries, the quality is one of the finest in the market, and Merlin Cycles is unbeatable with their prizes. The mech works flawless.
