Description

Deity Copperhead 31.8 x 50mm Stem BronzeOur goal with the all new COPPERHEAD 50MM length steerer mounted stem was to design a lighter sidekick to our beloved Cavity Stem, but the results delivered a stronger, refined, and lighter super hero that we just could not break. All our designs are tested to failure, but the COPPERHEAD refused to give up! After millions of cycles on both stress and impact testing this stem refused to give an inch. At a super short 35mm reach, this stem is our answer

Our goal with the all new COPPERHEAD 50MM length steerer mounted stem was to design a lighter sidekick to our beloved Cavity Stem, but the results delivered a stronger, refined, and lighter super hero that we just could not break.  All our designs are tested to failure, but the COPPERHEAD refused to give up!  After millions of cycles on both stress and impact testing this stem refused to give an inch.  At a super short 35mm reach, this stem is our answer to today’s longer top tube designs with a zero degree rise to keep your weight evenly distributed for peak performance.  Don’t get it confused…the Copperhead is stronger than the rest of the stems on the market, but it is also a featherweight fighter. Perfect for any application from Trail/ All Mtn/ Enduro/ DJ/ Slopestyle and even DH, this stem will take anything you have to offer and keep asking for more!Features

Fit perfectly and very complete set of parts
Had everything I needed plus some extra parts in the kit. I probably could have just replaced the impeller for slightly less but while everything was disassembled you might as well replace the works. Included - Water Pump Impeller, Housing, Key, Face Plate, Face Plate Gasket, O-Ring, Seal Face and Carrier Assembly Oil Seal

Good quality, but could have used better instructions
The kit was complete, and all the components were well made. However, if you aren't somewhat mechanical, it would be fairly easy to install the gaskets and backing plate in the wrong sequence. With better instructions, this would be a 5 star plus kit.

Don't pay boat shops for over priced services!
Boat shop wanted $400 dollars for a new water pump replacement. Got this on Amazon and watched a few utube videos. Took less then 2hrs to take apart and replace. I put it in a Alpha 1 gen 2 lower. Very simple process.
