10.2g/set
Top gears.
Weight: see table below
Sealing: low friction 2RS seals
Construction: twin bearing system
Bearings: 4 Precision Ceramic Bearings
Material: self-lubing hi-tech polymer, alloy inserts
Compatibility: see table below
Extralie pulley wheels have been evolved to a greater degree
Rolling resistance is further reduced by custom developed ceramic bearings.
Each pulley wheel features twin bearings assembly for unmatched shifting precision.
Pulley bodies are 3d machined from highly durable and self-lubing polymers.
Extremely light and tricky.

**Tuning
Notes: several derailleur cages can fit a pulley with 1 or 2 more teeth than
the original.
Phased
pulleys were born to help chain guide on single chainring systems.
Pulleys with phased teeth (PH) can be applied also on standard double chainring
systems with the benefit of a higher shifting precision.
As example Durace has been tested with 12-14PH
