Bendix 2 speed Red Band and Yellow band hubs are great, and I have been rebuilding and riding them for over 20 years now.
It has always bothered me that they are so poorly sealed, and I finally decided to do something about this. After putting over 400 miles on a red band in 2022, and 1800 miles on a yellow band in 2023, I serviced both of them and found a disturbing amount of dirt and grit stuck in the outer layer of grease, especially on the drive sprocket side.
To counter this, I have come up with a set of O-rings sized to help limit the amount of debris that can enter the hub. Yellow band hubs have spaces that can accommodate 3 o-rings, red bands can handle 2 O-rings. The most important one needs to be installed while the hub is apart, the other two can be slipped over the assembled hub but of course this would be best to do right after being serviced. I’ll attach some photos later today. $17.50 shipped by USPS from Rockford Illinois.
