This is for stuff that is associated with learning.
I work at a failed school. San Francisco State University. It’s a terrible place if you are looking for a quality education. A good student can find opportunities anywhere but any of our students that go on to succeed in life do that in spite of us, not because of us. These are strong words. … Read more
I’ve continued to refine my SolidWorks modeling methodology and have been bringing older files into accordance with the new strategies. A new video explains more of this. I’d just completed the huge project of breaking down the CAD model for the dropouts so that I could build it back up a lot better. This doesn’t … Read more
I believe that my blog has now added a new branch of discussion. While I’ve focused on bicycles, motorcycles, and skateboards for the past few decades, the last year has attracted a new topic; academia and studentry. I am, without a doubt, not an academic but I’ve been adjacent for two decades with my work … Read more
The student becomes the master. I tease Ronen with this Star Wars scene. He’s very much a powerful Jedi. The Interview: http://www.peterverdone.com/wp-content/uploads/2025/02/2025-02-18-Ronen-Sarig_02.mp3 I met Ronen in about 2013. He was young then. I was younger then. In Fairfax Cyclery and in the parking lot we connected. This kid was different. His early fast time on … Read more
I was contacted by a student in my department (Physics & Astronomy) the other day. To satisfy a course requirement, he needed to interview someone from the department to get advice on his path through school and beyond. He probably asked the wrong person. I asked him if I could record the interview for my … Read more
When we work in engineering and design, we refer as much as possible to ‘first principles’, those datums or facts on which the entire project rests. “A basic assumption that cannot be deduced any further”. Everything comes back to these. They are both our lighthouse and safe harbor. In bicycle design, there are many of … Read more
I was doing a quick spin on the bike today. The mind clears when you’re trying to ride down narrow singletrack as fast as you can. I was bopping through Hobo Trail and I was thinking about Richard Feynman and his learning technique. Study a subject Pretend to teach a concept you want to learn … Read more
I’ve been working on my suspension bike design for about five months now. There’s no rush and I’m trying to do it right. I can prototype as much as I like in the computer and it doesn’t cost me a thing. What’s expensive is wasting money or time once I start cutting metal. I’m nearing … Read more
Here’s another from the message vault. The other day, a guy posts to the bicycle Framebuilder’s group on Facebook. His claims were that he understood the cause of Chloé Dygert’s recent crash during the women’s individual time trial at the 2020 UCI Road World Championships in Imola, Italy. It was a very gnarly crash as … Read more
Advice for the aspiring designer; Have lots of patience, keep working hard, don’t ever stop! I’m currently working on producing a new fixture for making my bicycle frames (a mandrel bender also but that is another story). I need a tool that will work better than what I have been using for modern geometries, mopeds … Read more
In photography and filmmaking, the joke is often made that “it can be fixed in post” to justify doing very low quality work. It’s true that there are a several small issues that can be fixed after the image has been captured. Some colors can be shifted, a smudge removed, subtle white balance changes, the … Read more
It was Thanksgiving a few days ago. Thanksgiving is one of only a few real holidays in the United States and it’s probably the most important. Important, as it’s not about turkey or shopping or even your crazy aunt and uncle. It’s about gratitude and that’s some good shit. I always try to focus on … Read more
侘寂. Imperfection is sometimes a strange kind of perfection. We’ll see a hot rod, motorcycle, or bicycle and it is such a terrible thing in the details but in that, it’s fantastic. Producing something like that takes time, wisdom, and a little bit of luck. Knowing just what blemishes bring out the soul of something … Read more
This post is about something few people hear but many need to. You are not an expert on bikes. You aren’t. No matter what you’ve convinced yourself of, you’re not. You make YouTube videos, you comment in forums, you go on lots of rides. Still, you really don’t know a lot about bikes. Everyone in … Read more
The general rule in the machine shop is to never make when you can buy. With some exceptions, you’re usually doing yourself a huge disservice by choosing to make something that is otherwise available commercially at reasonable prices. There are some exceptions to this but often you’ll end up spending more money than it would … Read more
Making the rounds this last week was a photo of a 4.5kg “mountain bicycle”. It can’t possibly function, but I’m sure few realize that. Last week someone I know was bragging to me about how amazingly light their bike was (although, they get a pass, being pro AF). I’ve been planning to get around to … Read more
I am a critic. The clip below is from the Screen Junkies Honest Trailers and it got me thinking this afternoon. After a savage “Everything Wrong With:” from CinemaSins, and back and forth discussions with critics at ComicCon; Kong: Skull Island director Jordan Vogt-Roberts joined the fun with the Screen Junkies crew to help make this critique of his … Read more
Today, we don’t design on paper… I was recently reminded of this topic by a message board thread. A kid wanted advice advice on drawing a frame. Countless people chimed in giving horrible advice. I often find that the less someone knows the more they will pass off their opinion as truth, while lacking any … Read more
I cruise various bicycle frame builder message boards and the frame builder’s Facebook page. I haven’t had any interest in posting there in a while but I did a lot in the past. The topics that get brought up are often topics that have been covered over and over so there isn’t much to offer in terms … Read more
Here’s something fun and useful. I love when I get to get all math-y… A long time ago (2006), I put a blurb up on my wiki. It was a re-post from long ago that I had posted onto a skateboarding message board, probably back in 1998 or so. My web site, wiki, and now … Read more
What the fuck is this? How is this even possible. This comes out of a $10,000 bike. It was ridden this way for over 500 miles, probably a lot more. This wasn’t a college beater. I just don’t know what to say. I’m absolutely appalled. I’m not an inocent. Not by a long shot. I … Read more
The stem is an incredibly important detail on a bicycle. It places the handlebar in the proper position relative to the bottom bracket and the saddle regardless of what lies beneath it. Where the stem holds the handlebars can make a bike fast on climbs, or fast on descents, or great for all day comfort. There … Read more
I absolutely love trigonometry. It’s how we come to understand circles and curves. I work at the Physics & Astronomy Department at San Francisco State University. Every semester a few students will express their unease, confusion, and problem doing trigonometric work. Over the years, it’s been shown that, all of them, have never been given … Read more
