Powerband racing just posted a pic of what I assume is the new cone valve/trax combo, rebranded as WP Pro Components.Anyone have details on them? If so, what exactly has changed from the black version of the cone valves (aside from coating color)?


The Shop
DeCal Works Huge Plastic Inventory of UFO and Polisport kits.
Luxon 4-Post Bar Mounts
$189.95 - $239.95
New desing doesnt cost WP more so new sets should follow same range.
The big conversion is the shock with the new Trax mechanism that’s adjustable.
As little as they do in real life, the fancy coatings are a must have on a top level suspension. Who would want a Showa A-Kit if it had gold upper tubes and chrome lowers? the coatings is what we all (I assume) drool over.
Strange move on WP's part imo.
Pit Row
But I 100% agree I like the DLC or TiNi coated look all day ever chrome.
On the site it says available mid May at WP centers, so hopefully some test review info coming soon!
You can DLC (or TiN) aluminum, but it happens at such a high temperature that would kill the temper of the aluminum and you'd lose a bunch of strength. That's why you don't see much DLC coated aluminum, certainly nothing structural.
In order of higher to lower friction (stiction if you will):
Hard chrome, TiN, DLC, with a pretty big difference between TiN and DLC. Not so much between chrome and TiN.
While DLC will be lower friction than hard chrome, one a shock it doesn't matter all that much since there are hardly any side loads on the shaft. The swingarm takes all the side loads applied to the bike and the shock is mounted on spherical bearings so it really can't take any off-axis loading.
The side loads on a fork can be huge and coatings make a MUCH greater difference on a fork than on a shock.
All that said, the only reason I could see them moving from DLC to hard chrome on the shock shaft is cost reduction. But for a manufacturer DLC coating a shock shaft isn't that expensive... Seems like an odd move. Unless the shock shaft is aluminum?
