Have you ever been on a ride and thought, "I wish I could shorten or lengthen my stem on-the-fly?" We haven't either, but the 3fstech AIM stem is designed to do just that. A handlebar mounted remote releases the stem, allowing it to be set at either 55mm, 95mm, or 120mm in length. Total weight is claimed to be 400 grams, including the remote. For reference, "regular" stems usually come in somewhere between 100 and 150 grams depending on their length.
How much will it cost? Well, it certainly won't be cheap, with final pricing expected to be in the neighborhood of €275.AIM stem Kickstarter page.
