Seen anyone running these? Sorry no picture, I'm not good at the interwebs. http://www.easternbikes.com/a/products/parts/07Parts/07NewStuff.html In The Works Plastic BB Eastern has been working on some new products and we just wanted to give you a peek at one. This is a Plastic BB. It's light and will be significantly less expensive than a standard metal version. 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 Widely used in many industries While this product is still in the testing stage, a handful of local riders are running them with positive results.
