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. Do all stems fit all bikes?
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.
3. Are all mountain bike stems universal?
Yes, mountain bike stems are almost entirely universal. 31.8mm is the most common size with a few 35mm sizes coming in lately. So mountain bike stems are about as universal as it gets.
