Frequently Asked Questions (FAQs)
1. 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.
2. 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.
3. Do bike stems make a difference?
Stem length is one of a number of factors, along with head tube angle and fork rake, that affects a bike's handling. Generally speaking, a shorter stem will result in faster handling, while a longer stem will result in slower, more predictable handling.
4. Are bike stems universal?
Yes, bike stems are universal. Where they connect to the handlebars is almost always the same width. Where it connects to the fork steering rod is the same width. So there is around a 95% chance that a bike stem will fit your bike.
