Important stacking instructions
Do not stack all three spacer pairs together.
The 10 mm pair may be used with either the 50 mm pair or the 70 mm pair. Do not combine the 50 mm and 70 mm pairs, and do not use any configuration other than those listed above.
Use only the supported combinations listed in this description. Confirm that your final setup has appropriate hardware engagement and is correctly secured before riding. Failure to follow these instructions can result in excessive cockpit flex, damage, or a crash.
Note:
Bolts are not included – source stainless steel M5 bolts in the correct length elsewhere. Measure your existing bolts from under the head and add in spacer stack height to determine the correct length. Reach out with any questions.
Always torque to manufacturer specs when installing.
These spacers are 3D printed on consumer-grade equipment. I believe them to be safe to ride and ride them myself, but they have not undergone the same safety testing as stock components.
