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. What does a shorter stem do?

Shorter stems correctly orientate a rider's forward-leaning weight directly over the front axle, which has a range of benefits by mass-pressuring the wheel when descending. The result is truer steering response and better tyre grip in dusty or muddy terrain.

3. How does stem length affect mountain bike handling?

Using a shorter stem gives the bike quicker handling characteristics and a more responsive feel. A longer stem shifts your body weight towards the front of the bike and puts you in a better pedaling position, especially on those steep climbs.

4. Is 40mm stem too short?

Trail Bikes The typical mountain biker should use a 40mm stem. This is the best size for trail riding. This length will put you in a neutral position on the bike that is good for both climbing and descending.
