Modern downhill bikes have a lot of adjust-ability but their performance is hard to measure. If there was a system to collect data it would be easy to make adjustments with a scientific approach. Riders could also get feedback on their riding style and line choices. It could also add to the entertainment side of things by providing real time telemetry for spectators.
suspension compression rates
suspension rebound rates
when brakes are applied
hi duty cycles
hostile environment (cold/wet/dust/mud/heat)
needs to support quick mounting/removing
large sudden impacts
Sorry it has been a while since our last update. We have been doing field testing at local races. Learning a lot about what works and what could use more improvements. So far the basic idea works great. It is really quite quick to add the sensors and remove them from the bike which makes it very easy to use.
We got a lot of valuable data that weekend. Unfortunately I got a flat tire during the race run so my results were not stellar ( not that I try to hard to win these days anyway )
After Plattekill we went to Mountain Creek for the ProGRT race. Most of the major suspension companies were at the race providing tech support for the racers. It was neat to show them picrorico and get their feedback. They all pretty much have custom in house built telemetry systems for testing already but a few gave hints that a consumer product might not be too far away.
As far as testing goes we were getting good feedback during practice. Unfortunately during a practice run my rear wheel slid out on a root and I crashed. That would be the end of testing and racing for a while. Turns out I broke my left hand requiring surgery for pins and a hard cast. Being a small team with full-time jobs this put things on hold a bit.
We will continue progress though and be making use of this shiny new tool.
Being a hardware project we had to bring a ton of equipment with us to be sure everything we needed was available. I had a rough idea of what it would take to build a prototype but went on the side of caution and over packed. To get to the hackathon was quite a challenge itself. I rode my 55 pound downhill bike 2 miles to the LIRR with a 61 pound internal frame backpack filled with tools and a 14 pound backpack strapped to that pack. I should have planned that better by gradually bringing things in during the week and stashing them at Datadog HQ which is only a few blocks from the Manhattan Center. Besides being so heavy and clumsy it also turned out that I was traveling with the crowds of people going to MSG for the Rangers playoff game. Made for an interesting ride. Anyway I made it, met up with Dorian and we got the bike and all of our gear in.
Very cool project! I look forward to seeing future progress!
