Product Description
The front derailleur contains the shifting logic and enables the shifters to stay in constant communication with the whole system. Front shifting is the most perfect front shift available today. With automatic micro-trim adjustments, the chain is kept perfectly aligned and quiet.
- Quicker front shifting leads to stress-free riding
- Programmed and precise shifting with less chain drop
- Automatic chain guide movement makes trimming non-existent
