What are the best Shimano components?

Shimano 105 is considered Shimano’s first performance groupset, and for many people it is the best option in combining performance, value and longevity. Ultegra is next and is very similar to Dura-Ace in terms of performance, though Dura-Ace is lighter.

Are all Shimano rear derailleurs compatible?

Just for clarity, current generation (10-, 11- and 12-speed) Shimano road and mountain bike components are not inter-compatible with each other because they use different cable pull ratios. For example, you couldn’t use a set of road shifters with a mountain bike rear derailleur.

How long does a rear derailleur last?
