Background:
This is part of a much bigger system design which is detailed here: Mountain Bike Data Logger
Update 7-26-2026: I put a rib on the top strut piece of magnet mount to stiffen vertically. I noticed a 45Hz peak in the measurements I am trying to fix. Also note I cut the top mounting eyelet off of the sensor. It would snag and pull down the climb switch sometimes.
Detail:
The rear shock stroke sensor is specific to my shock, Cane Creek Coil IL, but likely easy to modify design for others.
The top part, which holds the magnetic target, clamps onto the body.
The bottom part, which holds the sensor, is held in place with a special bracket clamped between spring and perch.
Still allows climb switch adjustment.
Voltage divider is used to reduce voltage for Artemis OLA board. This is built into wiring harness.
Print Settings:
I used PETG with 60% infill. Organic supports were used but minimal need.
Parts Needed:
Fasteners Needed:
M4-0.7 x 10mm Flat Head Socket Cap Screws (standard for ISCG)
M3-0.5 x 20mm Standard Socket Head Cap Screws
M3-0.5 Square Nuts
Installation:
The bottom mount snaps together with the existing aluminum spring perch. It is held in place by the spring compression. Even a small amount of preload is more than enough.
The top part simply clamps around the unused threaded body just above the top spring perch.
Sensor bolts are all pretty obvious. Just threads into plastic printed part.
Disclaimer:
This is just an experiment and I make no claims or promises on safety. What you do to your bike is your business and your decisions. I am just giving ideas on how we can instrument our mountain bikes to learn. This project does add sensors very close to rotating components that could stop your bike quick. Install at your own risk.
