11/16/2023 11:19am A few quick hit learnings from me: 1. The Mach 4SL was considerably harder to dial in than I thought it would be but after spending a bunch of time assessing why that would be I came to the conclusion that the sensors were not stable enough. It was hard to get them right because that bike just doesn't have...

11/8/2023 8:56am One other "epiphany" that I should have included. I spent way too much time trying to go with small changes at first. I didn't really see progress on hitting the right values until I went extreme and then backed it down. Kind of a binary search principle. I set my shock to 110psi and my fork to 55psi (fully kitted...

11/8/2023 8:49am Been following this thread because the technology is interesting and it’s cool to see it grow. Looking at some of that output and some people’s questions it seemed like a good time to add this. As a greater quantity of data gets generated from the bike, i think a problem similar to one faced by a lot of researchers working on large datasets is cropping up—data dredging. If all you start with is a lap time or a ride-feel report and try to go into a dataset to try to suss out which of those many factors seems to correlate...

11/8/2023 8:49am These are good points - its an interesting discussion because on the one hand, some will argue that DAQ systems are pointless and can't tell you whats going on, and on the other you will see some people read far too much in to the data and expect it to give answers that just aren't there. From my perspective its just a tool - a really powerful too but only one piece of the puzzle. I will still start out with listening to rider feedback or feel, and then hopefully the data might have a clue as to what direction...

11/6/2023 11:49am Not quite yet but I will share every meaningful thing I find. That's the best part of forums like this. Too much work is not leaving me with enough time to get regular runs in for the time being but as I progress I will try to show the results. I will tell you that I feel faster (and Strava/GPS...

11/6/2023 11:42am Awesome to hear! Sounds like you have a nice "break through" moment. I had that as well when the @DialedTelemetry told me about trimming my runs down. So stoked that info helped you as well! Any good data to share with us? Ive been testing on my motocross bike and it's been very intertesting! The engine squat and load on the rear shock is really hard to add into the mix. Anyone here have experiance with motorsports Data?

11/6/2023 6:33am I finally had time on Sunday to get a run in and I'm much closer now. A few thoughts: 1. BYB has the ability to trim runs and save them as new files so that I can isolate that shorter time period. This is really helpful and I used that, combined with some previous runs to do compares. 2. I'm...

11/3/2023 9:35am The parent I saw was most certainly designed to hold a shifter cable. I can't say which bike but the the bike I saw with AXS that was being powered by the bike battery used a little block that clipped in place of the battery and a small wire ran from it into the shifter cable hole in the chainstay with a little rubber grommet.

11/3/2023 8:55am I haven't seen the patent so this may be way off but I wonder if it is what we see on the Powertrain. That has a cable port because it connects directly to the battery of the bike.

11/2/2023 10:46am Thank you. In retrospect that seems so obvious. My initial thought was to give it a ton of data but I can easily see why that blurs the results instead. Especially with me stopping to examine the extremely techie climbs before attempting them. I’m laughing at myself for not analyzing that correctly. Really appreciate everyone that has chimed in.

11/2/2023 10:17am Ok this graph gives me the best info! 1) in my opinion that run is way to long to collect data. For a few reasons, the time that you are stopping, it’s average the data of the suspension extended, at 0 travel. So that’s changing all your overall numbers. 2) I would only test a section that is 2-5 minutes max. And repeat that section over and over so you can see/feel the changes. Or I believe you can just select the section you want in the app and review those small segments. But I’ve found at a certain point...

11/2/2023 7:07am Most of the trail is flow but that section of the run definitely includes one significant drop that I didn't exactly nail perfectly but it doesn't surprise me that 40mm would be the average. I see 28.4% showing as the average which seems reasonable. The max of 81.4% was that drop I mentioned. Here's the stack view and the line...

11/2/2023 6:38am Yeah, I can leave it off and see what I get. Good idea. Will have to wait a couple of days to do it unfortunately because I'm not going to have time until at least Saturday but will definitely try it on my next ride multiple ways to see how it is reflected in the charts.

11/1/2023 11:23pm No calibration needed per BYB's manual and there's no sensor at the rear axle, only at the shock itself. Here's the picture I have for the current request. Thanks for your help.

11/1/2023 9:36pm Thanks. Very helpful. I suspected that might be an issue but it has moved as I've moved the numbers so at least it is consistent. I was very surprised that I wasn't hitting more than 50% of the travel as well as at least one drop today was very significant and should have resulted in more than that. Weight fully...

11/1/2023 3:33pm I've had a few runs with the BYB Tech setup attached and I'm getting closer but I'm still not there. One thing that is striking is how far off I was to start with based on the info I collected. All of my settings were very close to the manufacturer recommendations and everything I've ever read or seen so it...

10/29/2023 4:45pm Also, taking a look at my data I'm guessing my brake sensors were too close and picking up braking when there was none. Those seem tricky to get exactly right because I tested it before going out and all was good but I must have hit enough bumps to move them. Time to apply some duct tape and keep the...

10/29/2023 4:07pm Did 12 miles with the BYB attached to my Switchblade today. I originally had it on my Mach 4SL but I feel like that one is pretty dialed in while I felt that the Switchblade needed to be checked as I haven't ridden it much lately and I'm back to my normal weight (185lbs) after putting weight on after an...

10/28/2023 11:57am Finally had some time to make a 3D printed top mount. I also drilled and tapped the lower shock bolt. Now I can add or remove the rear sensor without touching the shock.
