1995 Kona Cinder Cone. Dont know why because the bike that replaced is arguable better with rockshox suspension, V brakes, aluminum frame but somehow the Kona was just special.

I use these exact shoes. If you are into XC or marathon racing and need to get the best performance from your shoes these are not for you. They have a bit more flex in the soles than the shoes you arer used to. If you are just riding for fun and wear the shoes alot while off the bike, grabing a beer after the ride, or you have to get off and push these will be way better. They are way comfier off the bike while still being good enough for normal riding. Think of it like shorts. If you wear lycra these arent for you. If you wear baggies then they likely are.

Ive uploaded it to Printables: https://www.printables.com/model/876044-bicycle-bell-adapter

Made a bracket to mount my bell at 90 degrees so the button thing is easier to reach. Doesn't even use any extra screws.

Recently designed and printed this mudguard for me EEB. Pretty chuffed with it.

Glad it worked out. Any pics of the finished product?

To be honest the sun reflecting off the top tube was a bit of a problem but only because this bike has a relatively flat surface on top. On bikes with round top tubes it isnt a problem.

My main reason is that I felt sand blasting would leave a satin finish which would mean extra effort in polishing. From pervious experience doing this I know most of the tubes are relatively shiny from the manufacturer so this made the polishing easy. Also, to have it sand blasted would have cost more than the cost for the paint stripper. Unfortunately, I cant recall the brand. I think it was Alcolin but cant be sure.

Looks good. Always liked those old Volcans. Have you checked that the back wheel doesnt hit the back of the seat tube when the rear shock fully compresses? It looks very close considering the wheel is gonna move up and forward as the suspension compresses.

Its a 2 in 1 sensor. We just ignoring the wheel sensor. https://online-bicycle-shop.co.za/products/giantant2in1speedcadencesensor

Its possible. I didnt write the app myself. Ive spoken to the guy who wrote the app for me and he is confidant he is doing it correctly. The sensor only reports 3 things, wheel rotation, crank rotation and battery life.

I honestly have no idea. Im a mechanical person, my knowledge of such things is quite limited but I wouldnt expect the level to reach 100% after so much use.

The machine is such that the shaft we want to monitor is mounted to a assembly that rotates around a second shaft. As such the sensor will be rotating around a different center to that of the shaft we want to measure. Im pretty sure a accelerometer based sensor would get confused. Im pretty happy with the performance of the reed switch sensor, just confused by the battery life it reports.

Does anyone know the ins and outs on how these sensors work? Specifically the reed switch based units with a magnet on the crank and how their battery systems work? The reason I ask is the company I work for builds automated machines and we have a need for a compact wireless sensor to monitor rotation. We couldnt find a industrial sensor small enough but being a cyclist I had the idea to use a cadence sensor. The battery life was a concern so we went and bought one and set up a test with a motor and the sensor and have had it running at 120rpm 24/7 for around 3 weeks now. We wrote a basic app on a PC to log the the signal and battery life. We are a little confused as the battery life the sensor reports seems to fluctuate a lot. It sometimes drops as low as 37% but then goes back to 100% later. Mostly it sits between 80% and 100%. The sensor uses a standard CR2032 coin cell that isnt rechargeable. My theory is the sensor has a coil that generates a current each time the magnet passes and this charges a small internal battery. During use the sensor uses this battery and this is the battery level that is reported. The CR2023 battery is only there to power the sensor during sleep mode when not in use. Can anyone confirm this? The sensor we bought is a Giant 2 in one unit.

Made this yesterday to remind me whats waiting when I get back from my ride.
