Strong and lightweight piston.  This is the new version with the improved rack design.  The body is made from a Dupont polymer material, whilst the rack is made from steel using a metal injection molding process (MIM), and then heat treated to improve strength.  Easily one of the best price / performance pistons available now.

The pickup tooth has been slightly thickened for reliability (around 0.5mm), however this might lead to it contacting the sector gear.  I tested on the Lonex and E&C with a set of SHS 18:1 gears and was fine, however do check.  If you do get contact you can just grind down the extra material.
