Frequently Asked Questions (FAQs)
1. How do I know what size stem I need for my bike?
Know the length by measuring from the middle bolt of the bike's headset top to the center of the handlebar. Ensure that you measured the length in centimeters or millimeters. A bike stem length usually runs in 10 mm increments and starts from 70 mm to 140 mm.
2. How do I know what size stem to Buy?
It's fairly easy to measure with a ruler or tape measure. It's usually a discrete number of tens of millimetres (so 80mm, 90mm, 100mm), although really short stems can be 35mm long. Helpfully, a stem's length is often printed on it, often with additional information such as the rise and handlebar clamp diameter.
3. Will any stem fit any bike?
Stems are available to fit a range of steerer tube sizes with 1 1/8” being by far the most common on both MTB and road bikes. However some models are also available for older bikes with 1” steerers (although a shim can also be used to make these fit standard stems) or for gravity bikes with 1.5” steerer tubes.
