UltraPulley
from 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 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
