I have made several comments on some of my YouTube videos in regard to LightCarbon’s stock rear derailleur hanger for their gravel frame LCG-010-D. Since then I’ve been getting a few questions asking to clarify what I mean by this. This article aims to answer some of those questions. Let’s start from the beginning. LightCarbon…

Katy Trail Preparation
With bicycle racing taking a hit in 2020 a few friends and I decided to knock a multi-day bicycling trip off of all of our bucket lists. The initial planned crew consisted of myself, Khanh, Aldo and Khuong; however, last minute tooth issues prevented Khuong from attending. This was a proving ground for me personally…

995.1 Miles on a Hambini Bottom Bracket
The day has finally come. I have hit 1000 miles on my Hambini Classic BB86 Bottom Bracket, well. 995.1 miles to be exact, but I simply could not be bothered to get back on the trainer and crank out 5 more miles. The Hambini bottom bracket has done well so far. I have had no…

I chalked it up to poor posture and continued to work on proper form and core strength, but then I came across a Francis Cade video that featured Bike Fit James discussing handlebar choice and how to measure for…

NASBerry Pi
Adventures with a Raspberry Pi 4 Model B, some hard drives and some Chinese circuit boards. The Raspberry Pi 4 Model B contains two USB 3.0 ports, something that previous versions did not. This upgrade finally opens up storage array possibilities as the RPi still has no SATA connections. USB 3.0 has a theoretical max…
Mini-ITX Home Linux Server
This is just a general server build write up. I am only listing prices to show what is possible because it is unlikely you may find the same deals on these components that I did. You could also go with standard heat sink and fan. I opted for the radiator because of my case situation….
Cheap pH Meter for Raspberry Pi with ADS1115 and PH4502C
If you search for “raspberry pi ph meter” you’ll quickly learn that there are very few affordable options when it comes to digitally monitoring the pH of your nutrient solution. For a while Atlas Scientific dominated the search results, but I believe their kit was around $200 at the time. The kit has since come…
