Während des Presselaunches ist ein Mangel bei Pinkbike und bei Jeff Kendall-Weed aufgetreten. Der Bolzen vom Hauptlager hat sich gelöst. Das Problem ist, dass man dafür die Kurbel demontieren muss, um mit einem Werkzeug diesen zu befestigen. Das sieht man in JKW Video bei 12:47 im Kapitel "loose pivot":

Auch Dario DiGuilio von Pinkbike hatte dieses Problem:

"The main pivot is concentric to the bottom bracket, and each bike ships with a special tool to tighten that hardware. This requires removal of the crank and drive-side bottom bracket, but it's a straightforward and easy job. Some of the early production bikes (including mine) were lacking Loctite on this hardware, and as a result the main pivot would come loose quite easily. If you experience that issue, it's worth checking to see if any retaining compound exists on the threads."

"The main pivot came loose numerous times right off the bat, but it turns out the factory-spec Loctite wasn't added for my test bike's build. After adding some myself, things stayed tight, which I'm thankful for considering the fact that you have to pull the cranks and bottom bracket in order to tighten the main pivot with a proprietary tool. "


Rocky´s Produktmanager sagt dazu:

"Every bike and frame comes with the tool in the small parts box; no need to hunt one down and spend $50 if you can find it. Additionally, with correct loctite application and 25Nm of torque (which isn't much) the pivot will never come loose again. We have thousands of KMs put on test bikes at RMB without the pivot coming loose. This includes Whistler Bike Park laps with its endless supply of brake bumps."
