Kogel Bearings is expanding their range of ceramic bearing derailleur pulleys to mountain bikes with the upcoming SRAM Eagle models. The wheels are made of aluminum, rolling on Grade 3 ABEC 5 hybrid ceramic bearings with steel races, same as what’s used in their bottom brackets, plus their off road seals to keep gunk out. The upper wheel has 12 teeth and the lower has 14.
They’re not available yet, but Kogel’s giving Bikerumor readers the chance to test them as part of their final testing phase. They have ten pre-production samples and want real rider feedback before pulling the trigger on a larger delivery. Interested?
From Kogel: “You will receive a set of Eagle Pulleys for $60 (less than half of the final retail price) in return for your feedback and some kind words on your social media. All applicants will be considered for future positions as product tester for new developments. Please fill out the application form on the website, add a short description of what makes you qualified to give detailed feedback and what you will do to put the pulleys to the test.”
In addition to the test opportunity, Kogel just launched a new website and is raffling a set of their road derailleur pulleys for every 100 new subscribers to their newsletter.
