Machined from
a single block
The P-Line housings are manufactured through a CNC machining process. After the intricate, multi-step machining process, the raw block of 7075 aluminum is transformed into two precisely manufactured case covers which fit together perfectly. Of the original 1690 gram block, only 158 grams remain.
Aluminum is one of the most recyclable materials: shavings, rejected parts, and even operating fluids are reused and reprocessed many times.
Design of the gearbox types
Common to all gearboxes is the spur gearing consisting of two sub-units connected in sequence. The individual gear ratios are derived by matching the two sub-units with various cog pairings. The P1.18 gearbox is built using a 6-gear unit mated to a 3-gear unit – a 6 x 3 gearing type. The P1.12 gearbox is a 4 x 3 type.
Gearing optimized for touring use, from trekking to MTB. With a 600 % gear range, the P1.12 transmission far exceeds the performance of a comparable derailleur.
