Sheldon Brown's Bicycle Technical Info

This website is such a treasure. When I was first getting into bicycles in 2013, it was a mix of Sheldon Brown and the local volunteer-run co-op that taught me everything I need to know. He is himself a generous spirit, advocating for DIY tooling, repair, and reuse.

I would highly recommend anyone into bicycles to try building their own wheel using his article.

This is my favorite kind of website. An individual going into depth on a topic they're passionate (in the true sense of the word) about. Another example is Dan's Motorcycle Repair Web page [1]. A collection of such websites would be awesome.

truly awesome how many ways you can go deep into something. Would have never thought to spend so much time on derailleurs

I started checking out Dan's Motorcycle Repair Web page, expecting to read about Motorcycle Repair, and the first thing I do read about is the Bible. Good lord!

Yeah. There's probably tens of thousands of internet users worldwide with that same story. Myself included: when I was fixing my Bianchi retro road bike's derailleur etc some 20 years ago as a univesity freshman, this site was a definite gold mine, immensely helpful, and taught me a ton. One of my favorite procrastination rabbit holes as well back then. :) And -- a prime example of 1990s era internet and information freedom and layman-level enthusiasm -- selfless sharing of knowledge (and, I wonder if he also used Notepad to write the HTML :). Thanks, Mr Brown, for everything, all the way from Estonia!

PS, interesting to note that Mr Brown seemed to be quite a fan of sci-fi books: https://www.sheldonbrown.com/org/books.html

Same. I built my first wheel according to his specs. His whole website is so helpful and thoughtfully written. RIP.

My quick story: I built up an old 90s cyclocross bike and his website was the main reason I have this beast of a frankenbike gravel bike. I found his article "8 of 9 on 7" and it changed my life: Take a 9 gear cog, remove one, and it fits perfectly on a 7-speed cassette body.

Then I found his other article on an alternate wiring for a shimano mountain bike RD-310 7/8 speed drive train (which unlocks 9-speed ability), which thus let me use the rugged 7/8-speed derailleur for the cassette WITH shimano dura-ace indexed bar-end shifters (which use, get this, 9-speed spacing on an 8-speed index because it made their system "proprietary"). All of this works together flawlessly <3 <3 RIP sheldon brown.

> Sheldon Brown, a beloved iconoclast bicycle tech guru, died Sunday from a heart attack. He was 68 63.

Curious, what does "He was 68 63" mean. Is it a bicycle gear joke about his age at death?

by xmddmx

Probably just a typo. He was 63.

That's actually more recently than I would have guessed. He had already departed by the time I discovered bike building in the early 2010s.

Time is strange.

by bsimpson

2/6/2026 at 9:02:03 PM

Ah that’s the reason why reading several articles on the site it felt out of date. For example the website states “Disc brakes have become increasingly popular on mountain bikes and are gaining some popularity for other bicycles” whereas in my experience disc brakes are popular for all kinds of bicycles.

by kccqzy

2/6/2026 at 11:40:46 PM

A lot of the information is indeed old, but then so are a lot of bikes. :)

Things are still being updated, primarily by John Allen. There's some writing about changes on the blog: https://sheldonbrown.com/blog/

(I have every expectation that he'd be quite pleased to entertain well-written updates from other parties, if anyone feels like being constructive. John is pretty easy to contact.)

I’m a little surprised to learn that Jobst Brandt outlived Sheldon Brown. He was 9 years older than him and Brown died at 63.

by hinkley

2/6/2026 at 6:33:07 PM

Came to say the same, I meet him once in his shop, what a great person he was. His wife also has a great amount of bicycle knowledge from what I heard.

by jmclnx

2/6/2026 at 9:37:12 PM

And the shop itself closed in 2021 after being open for nearly 70 years. I purchased my Brompton there.

If you liked Sheldon Brown (who was a treasure but the content is out of date now), definitely check out the Park Tool videos on YouTube. Calvin Jones, their director of education, recently retired after building an incredible library of instructional videos. As an amateur bike mechanic, I wouldn't have been able to build or maintain my bikes without Calvin's videos.

When I very briefly worked at a bike shop even some of the pros said they basically learned everything from Park Tool's Youtube videos!

Probably, yes. Try finding hard info about electronics. You really can't because there are a million zero effort sites by people that position themselves as teachers that really are absolute beginners themselves. And because they run Google ads they get priority in the results.

Sheldon's website is such an awesome relic of the internet we all miss. It still has a ton of relevant information if you ever find yourself dealing with obscure wheel sizes or something like that. Love it. RIP.

by czscout

2/6/2026 at 10:22:17 PM

i built a set of wheels following his instructions, using my brake pads as the reference for centering and truing, rode dozen of thousands kilometers on them, daily, part of my courier job. all the wheels i had after that old Mongoose were also built the same way. i cycle a 1997 Trek 430 as my main transportation and i freaking love it. soldered a custom rack for panniers after its geometry. farewell Sheldon, i literally read your entire blog, at least twice

if i had found a cycling crazie to date back in the days, i would certainly use "building a tandem" section of that blog for suuuure

by luqtas

2/6/2026 at 11:16:45 PM

Similar story here. Sheldon’s site took the mystery out of wheel building, at least for my basic needs. I was motivated by acquiring a couple of ancient Sturmey Archer hubs and wanting to put them on modern rims. Those wheels have been bulletproof.

by analog31

2/7/2026 at 12:47:19 AM

I did build a tandem based on Sheldon’s website. Never used it in anger on the road just cycle paths, used to have two kids on the back and a third following on their own bike. Because of the age differences between the kids it was one activity we could enjoy together on the local cycle paths.

It’s amazing what a difference just a little generosity of knowledge can make in other peoples lives.

by smackeyacky

2/7/2026 at 2:18:00 AM

Problem with tandems is the person in back (who doesn't steer) ends up doing way more of the work

by Melatonic

2/7/2026 at 4:40:28 AM

That's the stoker. Curious how you came to this conclusion. In my experience both riders can work as hard as they want. Or not. The only constraint is that both must have the same cadence.

by recursive

2/6/2026 at 5:51:12 PM

Sheldon was a wealth of information when I first started tinkering on my vintage 3-speed back in 2007. I would pore over these simple pages for hours in my dorm at college instead of studying. That led to dropping out and working in the bike industry for almost 10 years. It was a great preparation in problem solving and systems-oriented thinking before I got into programming.

I have a vague recollection of someone using a cheap old saddle and a rubber mallet to unstick a seat post.

Friends don’t let friends put aluminum posts in steel frames. Especially if those friends ride in the rain instead of wussing out and calling for someone to pick them up.

by hinkley

2/6/2026 at 9:41:52 PM

This is such a great website. I have enjoyed reading the articles in the past. It was the final push that inspired me to build my own wheel set instead of buying a complete when I was building my new mountain bike piece by piece. The art and zen (and frustration of trying to feed a shift/brake line through a frame), I tell ya.

I lost my "Clear Creek Bike Book" in the 1980's but eventually Sheldon made me not miss it at all.

It's not as comprehensive, and more corporate than Sheldon's site, but I currently love Park Tool's youtube channel (https://www.youtube.com/@parktool). They shamelessly mention their tools, but they frequently give alternatives like, you can get this park tool for pushing your disc brake pads back into place, or you can just use a plastic tire tool.

Highly recommend using his way of locking your bike - you can secure both the frame and rear wheel easily with a small U-Lock (harder to pry open)

Front wheel is still vulnerable but if you don't use QR skewers you have a huge leg up

Legend! I was a bicycle mechanic for a decade and this guy was our jezus! He influenced so many of my creative bicycle builds and exposed me to things like Alex Singer, Rene Herse, bicycle quarterly etc.. Big love for Sheldon and all his passion and work.

by behole

2/6/2026 at 7:58:14 PM

This is an incredible ressource without which I feel so many bikes and bike parts would go to waste. At the bike coop I volunteer at we’re trying to follow Sheldon’s footsteps by collecting information and procedures that are about making bikes & parts last for as long as they possibly can. What’s truly amazing is that all that documentation is amazing for both low-resource repairs on the cheapest of old parts and vintage part enthusiasts.

I think Sheldon Brown’s impact is a valuable lesson on sustainable engineering and the enormous role documentation plays in it

A fantastic resource!

by comprev

2/6/2026 at 8:01:22 PM

Similar story. As a student I bought an old bike and restored it thanks to lots of info I found from Sheldon. And building a wheel was such a fun but weird experience. Part mechanics, part art.

I ended up writing my thesis on bicycle wheels after this. Or, it's a thesis on optimization algorithms, but I managed to play around with optimizing wheels as the "real world application". https://news.ycombinator.com/item?id=10410813

I’ve learned about that website only four years ago. It is still helpful, teaches me how to install front derailleurs properly (as deep and far to the front as possible, better chain line with less trimming and better shifting).

I once posted in rec.bicycles.misc that I had just completed a 6 week solo bike tour of France. Someone asked me a series of questions about riding and camping in France and I spent about 10 minutes writing a response. Francophile Sheldon Brown asked if he could put it on his website and I was thrilled to say yes. He did so, formatting it and adding links and photos for the places I mentioned. (The page is still there but the photos and links are gone). Years later, a co-worker stopped by my cubicle and asked if I was the person who wrote that article -- he said it had inspired him to start bike touring ... I was again thrilled.

Ask HN: How does one archive websites like this without being a d-ck?

I want to save this for offline use, but I think recursive wget is a bit poor manners, is there established way one should approach it, get it from archive somehow?

by neoromantique

2/7/2026 at 5:46:30 AM

The Internet Archive probably has it already.

by userbinator

2/6/2026 at 10:23:28 PM

A single user's one-off recursive wget seems fine? Browsers also support it iirc, individual pages at very least (and saved to the same place, the links will work).

No doubt it's already in many archive sites though, you could just fetch from them instead of the original?

by OJFord

2/6/2026 at 10:27:00 PM

I ask in more general sense, if there is a way to fetch this stuff directly from webarchive or something along those lines.

Gotta hit the search I feel :)

by neoromantique

2/6/2026 at 11:54:43 PM

In the old-web days, I just used wget with slow pacing (and by "pacing" I mean: I don't need it to be done today or even this week, so if it takes a rather long time then that's fine. Slow helped keep me from mucking up the latency on my dial-up connection, too.)

I don't think that's being a dick for old-web sites that still exist today. Most of the information is text, the photos tend to be small, it's all generally static (ie, light-weight to serve), and the implicit intent is for people to use it.

But it's pretty slow-moving, so getting it from archive.org would probably suffice if being zero-impact is the goal.

(Or, you know: Just email the dude that runs it like it's 1998 again, say hi, and ask. In this particular instance, it's still being maintained.)
