Hi, Leslie.
Thanks for the review and you’re keen eye. We’d like to clarify some things: 1) the spiders are made using 6061-T6 material. Our stems are also made from this. 2) We don’t put the spiders through the rigorous polishing process as we do with stems, chainrings and other parts. Not all parts are polished after machining, and given the spider’s position on the bike and use, we opt not to add the extra step to the manufacturing process.
