25.4 mm

SR Sakae quill vintage (90s) stem aluminum 100mm 25.4mm brand new old stock black These stems are brand new old stock. They originated from the Klein bike factory in the 90s. I'm pretty sure the actual manufacturer year is 1991. My father in law worked there for years and accumulated many parts over the years he worked there and finally got tired of them taking up space so he gave them to me a couple of years back. They are in perfect condition and come in original packaging as pictured. These will be perfect for Someone building a vintage mountain bike. I will be listing many more new parts in the near future such as Deore derailleurs, brake sets, and much more. i will not be accepting returns being as these are new parts. So please know what you are buying and i will be more than happy to answer any questions -Thanks Please use at your own risk. We decline liability for any damages or injury resulting from use of these items, though they are new they are also decades old.
