Which version of the MTB Fork SAG Tool do I need for my fork travel?

The MTB Fork SAG Tool comes in three travel-matched versions: Short Travel for 120–150 mm forks (10–30% sag range), Medium Travel for 150–180 mm forks (10–35% sag range), and Long Travel for 170–200 mm forks (12–35% sag range). Choose the version that matches your fork's travel specification. Always measure from the bottom of the sag ring for an accurate result.

What is the difference between the Bio-Plastic and Ultra Strong Plastic options for the MTB Fork SAG Tool?

The Bio-Plastic (PLA) version is 99%+ bio-based (corn), offers a matte finish with crisp print detail, but is not heat-resistant — do not leave it in a hot car. The Ultra Strong Plastic (PETG) version is more durable and heat-resistant, safe for toolboxes, cars, and wet conditions, though its surface finish is slightly shinier with less print detail. Choose PETG for outdoor or high-temperature storage situations.

How does the MTB Fork SAG Tool compare to using a zip-tie on the fork stanchion?

A zip-tie shows where the sag ring stopped but gives no reference for what percentage of travel that represents. The MTB Fork SAG Tool is a calibrated four-sided measuring stick with sag percentages printed directly on it, matched to your specific fork travel range. This eliminates the manual calculation step and reduces setup error.

How do I use the MTB Fork SAG Tool correctly?

Slide the sag ring down to the dust wiper, then get into your actual riding stance — do not stay seated. Compress the fork slightly to release static friction, then let it settle to neutral. Read the sag percentage where the sag ring aligns on the tool, then adjust air pressure as needed. Shockwave Parts also points to a walkthrough by Vorsprung at the 5:20 mark of their setup video for additional guidance.

Material Notes & Warnings

“Stronger Plastic” (PETG) is more durable and heat-resistant, safe for toolboxes, cars, moisture.
PLA is 99%+ bio-based (corn) but is not heat-resistant, do not leave PLA in a hot car.
Don’t step on the tool. It’s precise and functional, but not indestructible.
