step1makeart on August 8, 2025 5:59 pm There’s not a huge variety of new 1″ threadless stems these days, but you can help your search for them by using the key words: 1″ threadless Nitto, Velo Orange, Rivendell, Crust, and a few other companies make 25.4 bar clamp stems, and even some 1″ threadless stems with 25.4 bar clamps. Using a shim you can fit a stem sized for a 1-1/8″ steerer on your 1″ steerer, which opens up more options for you to choose from. e.g.: https://velo-orange.com/collections/threadless-stems/products/threadless-stem-25-4?variant=53101919367 + https://velo-orange.com/collections/shims-adaptors-accessories/products/stem-shim-1-to-1-1-8 NB: that’s a pretty steep stem angle, so I would recommend a stem angle comparison tool when choosing a new stem: http://yojimg.net/bike/web_tools/stem.php This sub is really for bike repair questions, so don’t be surprised if this post is locked. /r/xbiking is a good place to get plenty of stem options. Plenty of people over there running 1″ steerers still.
