Visualizing Damper Performance

May 21, 2020

We have been working on a way to visualize damper performance for a while. Over the years of analyzing data, there were still some lingering questions we had about damper performance and quantifying what you are feeling. We pay close attention to the compression and rebound terminal velocities. From the picture below, you can see that every stroke, compression or rebound, has an acceleration phase followed by a deceleration phase. Between these two phases, you achieve max velocity. At the end of the stroke, you are at zero velocity and you are starting another stroke.

Leveraging the Scalene Triangle Sensor Method for difficult bikes to attach a sensor.

April 14, 2020

We’ve been mounting sensors to bikes for 3+ years now. Some bikes are really easy, others are really really difficult. There are a class of bikes that have placed the shock deep in the frame, making it really difficult to mount to. As long as we can take some simple measurements and we know the leverage curve of the bike, we can measure something other than the shock and translate that motion to the rear axle motion.

The Science of Using Data to Tune Modern Mountain Bikes.

March 04, 2020

This blog will cover topics about data analytics on bicycles. For many of you, this will be your first look at data specific to bikes. Rest assured, these are not abstract concepts and we encountered all of this for the first time when designing our system from scratch. Before we dive into data, we'll explore what your goals should be when tuning your bike. Then we’ll go into how you go about this process using data.
