Rider tuned was the aim of the new DEORE developments. That has been achieved and the new DEORE is the group of choice for many different bikes and riding styles. From cross country to trail, from hardtail to full suspension, DEORE has something for every need. What's more, DEORE components are top quality and highly durable.
