Mountain Bike Quill Stem. Quill Stems View all stems Handlebars Aerobars Drop Handlebars Mountain Handlebars. A bicycle stem can also be referred to as a gooseneck, and it's two big forms: quill and threadless stem.
Removing and relubricating a stem yearly is a good idea, especially if the bicycle is ridden in wet weather. See Jobst Brandt's advice on stuck stems in case you can't loosen the stem. This is a nice choice for that classic mountain or touring bike.
The quill of the stem and the bolt threads should be greased, to help prevent them from corroding together.
They are often found on older model mountain bikes and lower-end department store models.
Be careful not to overtighten a quill stem. The stem is the component on a bicycle that connects the handlebars to the steerer tube of the bicycle fork. The type that fits your mountain bike depends upon what type of headset you have, which accommodates either a quill stem or threadless stem.
