I opened up my BYB fork sensor to clean it up - was a little easier than the AIM ones were - its a snug fit but not as tight since the screws hold it in place, so can be carefully pryed apart with a metal spudger or blade. The wipers looked pretty good, a tiny bit of dirt in there so I'll clean it out, replace the o-rings and add a tiny amount of thin super lube grease to the contact points to reduce friction and give smoother contact for the wipers. It had quite a lot of play...

I love the DIWhy vibes from the last few pages 😍 I have been working a lot on the App and the Firmware for the mast month or so. I have made a lot of progress into packaging it into end to end usable, both on desktop and mobile. Major changes Live data! Now you can stream the sensor readings from a connected DAQ in more or less real time (20-30ms delay). You can set the time on the DAQ and you can edit and replace the configuration, without dealing with memory cards and text files! You can also change...

Why not just install the appropriate coil to hit your target sag for 150 mm travel, which you would normally have to do anyway, and be done with it? I can't think of many situations in which hitting a bottom-out bumper would be preferable to having a little extra travel in reserve.

I haven't opened my byb pots but they can usually be pryed open and you will find wipers on the end of the shaft, which contact the resistive surface on the outer tube. Clean these up with contact cleaner, and you might want to gently bend the wipers out slightly so they make better contact too. To get it apart, there might be a grub screw to remove first. My aim ones where pressed together which needed careful gripping to pull apart. Ill have a look at my BYB ones tomorrow though, pretty sure they need it too

These are old photos but hopefully you can figure out whats going on inside them! They are all constructed in a similar way

Not everyone agrees but in my opinion having the rise inline with the fork is the neutral roll position. (Gwin made a video on this btw). Why? Because it doesn't affect the steering geometry as you increase or decrease rise. If you run the bars straight up then as rise increase your hands move further away from the steering axis. The steering axis is inline with your head tube angle so it's pointing back about 64°. This has the same effect as running more spacers and a longer stem. You can't cheat the reach! Moving your bars around doesn't somehow...

I was curious where some of you land on for shock velocities. I know different systems will record different velocities but I was reading the motion instruments user guide and saw this - "Next focus on high speed compression. If you are riding really tough downhills, your max speed range will be in the 3000 mm/s range. Enduro pros are in the 4000 - 5500 mm/s range. Downhill can achieve speeds > 7000 mm/s. You want your wheel up and out of the way, if your fork is over damped on compression, something has to give, and it ends up...

@synBike That looks like super nice functionality! Making it easier to mount away from the shock is a big help for sure I've nearly got a working analog rotary sensor - should be fairly easy to plug it in to any BYB system, and the potentiometer uses a universal mount that plugs in to a custom bracket for each frame. I moulded the 6mm hex with knead-it (I think JB weld plastic weld is the closest thing) around the potentiometer shaft. If it works I'll try and tidy it up, maybe find a better potentiometer for the job too. Just...

I have been seeing the request for leverage curves for offset-mounted linear sensors come up quite a bit more in the last 12 months. If you don't want to calculate this manually I finally got around to actually surfacing this functionality in the UI. The basic process is: - measure your sensor eye to eye length at full extension (or what you want full extension to be, recommended to have a little buffer) - enter the stroke (only required for the visualization) - drag or enter the position points. For convenience the length is fixed and you can just move...

That was me, and a lot of fiddling it was too. But it's been bombproof. Happy to share the files if there's interest.

RAD is boot fitting. FC/RC is mounting location of bindings

I've done it a very similar way in the past - I think this was an aluminium bar or timber board attached to the frame parallel to the "ground". I recorded the points then plugged it in to excel and used the fitted trendline to create the leverage curve. Although this was using the Aim system where you could make a custom math channel using that equation directly in the software I've been making progress on a set of tools to help with set up, DAQ and frame measurement - *testing magentic encoders as rotary sensors, and also a tool...
