Eastern's Prototype Plastic Bottom Bracket

Eastern Bikes just sent over a photo and details of the plastic bottom bracket it has in the works.

We just wanted to show you the Plastic BB that Eastern Bikes have been working on. It's light and will be significantly less expensive than a standard metal version. We are testing it now and will keep you updated with the progress.

* Manufactured from bearing grade self-lubricating polymer
* On a Spanish bb you would save roughly 6.5 ounces
* We have made one small production run and are currently testing with positive results
* This will not be the final production model
* Basically the cup presses into the frame with a lot less effort than a normal bearing and then the “bearing” fits pretty tight on the spindle and spins inside the cup
* The bearings are made to do away with the stacks of washers most people use, it will however come with a few polymer washers if you need to adjust the spacing
* While this product is still in the testing stage, a handful of local riders are running them with positive results. * This is something that we are just testing. If it doesn't meet our expectations we will not put it out.
