Draft. Last site update post was March 2026, so this covers roughly May to September.
The last one of these was in March. Since then most of the work went into three areas: the build editor, a lot more data, and a handful of new pages that came out of research I was doing anyway.
The build editor got a rework
This was the big one and it landed over the last two weeks.
All the screenshots below are my own bike, the 2026 update of my LightCarbon LCR018-D, which is public if you want to click through it: https://mybike.parts/b/EIEDmhLtDHkwMzvoPG0MnA
A build is no longer a flat list of parts. Every build now has a wheelset, and you can hold two of them in one build (summer and winter, road and gravel) without duplicating the whole thing. Groupset and cockpit slots are grouped the same way, so the editor reads like a bike instead of a spreadsheet.
My bike has two wheelsets, a deep road set and a light gravel set. Both live in the same build and only the one marked "in use" counts towards the weight and the price at the top.
Other things that changed:
Part state: Each part is planned, ordered or installed. There is a "Mark everything installed" button for when you finish a build in one go.
Shopping list view: The same build, sorted by what is still missing, sortable by hand.
What it actually cost: You can record the price you paid per part. This is private by default, and the privacy toggle now actually means something: it is stated at the table so you can see what other people will and will not get to see.
Configurations: When a part has variants (a 50 mm and a 65 mm version of the same wheelset), you pick the one you bought when you attach it.
Editing without leaving the page: State, configuration, price and notes all save inline.
Photo gallery: Several photos per build, reorderable, the first one is the cover. Swipe on a phone, lightbox on desktop.
Description and links: A build can have your own words and a few link tiles, and the public page shows your text, the summary and the links in one box under the title.
Accessories are split into named shelves now: bags, lights, one computer, bottle cages.
Prices are formatted in one place, in whole units, grouped, in the currency of the build.
The upgrade case is the one I built this for. Most of my bike carried over from last year, so those parts are marked as already owned: they keep their price for the record but are struck through and badged Owned, and they drop out of both the upgrade price and the shopping list.
What is left is the shopping list: the parts that still have to be bought, with their current price and a link each. On my build that is 14 items, not all 39 parts.
936 builds exist at the moment. If you have an old one, it is worth opening it again.
More parts, more brands

Wheels came in from ICAN/Triaero (26), Superteam (22), Winspace (21), LightFast (17), XMCS (14), 10PLUS (12), Elitewheels (12), 8Lien (11), Light Bicycle (11), Tukus (8), Avian (7) and TOCCAY (7).
Frames came mostly from Tideace (21), Avenger (12), Quick Pro (10), ICAN (8), Mondince (7) and Spcycle (6).
New brands this period include Ravemen, MVMT, S-Ride, IMTOS, Shanghai Forever, Dragon, Ceccotti, CAMP, Missile, ZC Rubber, Arisun, Wellgo, GANNA, SPEDAO, Kapvoe, YBN, Meinier, VOOK, WUZEI, Falco, TOCCAY, NEXGA, MEROCA, AIRBANK, FLEXTAIL, CHEJI, Neutron, 8Lien, TRIGON and BladeX.
There are also a few new categories, because some of the old ones were doing too much work: Rims separate from wheelsets, Electric Pumps separate from pumps, Shoes separate from Socks, Skinsuits, and Groupset Parts.
23 brand shops are crawled automatically
Instead of adding products by hand, 23 brand shops are now crawled by us directly, either through their product JSON or their listing pages: LightCarbon, Tideace, Dengfu, Winspace, Yoeleo, Superteam, ICAN, Farsports, Elves, Avenger, Avian, Quick Pro, TOCCAY, Neutron, 8Lien, LightFast, Magicshine, XMCS, 10PLUS, PandaPodium and a few more. New products usually show up here within a day of going live in the shop.
Proper spec sheets: wheels, lights, cockpits
All those new wheel brands are the reason this had to be sorted out. A Chinese wheel brand does not sell a wheelset, it sells a matrix: the same rim in four depths, each in hooked or hookless, each with a choice of hub, freehub and spoke, and every combination its own weight and price. Adding twelve of those catalogues the old way would have buried the site.
So: wheelsets used to be one record per depth, which meant six near-identical pages for one model. They are now one record with configurations: 1179 of them across the catalogue. The variants table shows depth, weight, rim widths, brake type, freehub and tyre range per configuration, and each configuration can point at the exact shop page that sells it, with its own price.
The spec attributes behind that are new too: internal and external rim width, hook or hookless, ERD, spoke count, hub engagement, bearing type, freehub standard, axle standard, tyre width range and rider weight limit. Rims got their own category, separate from built wheelsets, with hole count, spoke hole type and rim depth.
Other categories got the same treatment while I was in there:
Lights: beam pattern, mount type, waterproof rating, StVZO approval, battery capacity, max output, runtime at max output, max runtime and the lowest steady mode. The last three are the ones that matter and the ones brands are vaguest about, so the extractor is explicitly told not to read a headline "46 hours" number off a flash mode.
Handlebars: type, width, hood-to-hood, reach, drop, drop-to-drop, flare, backsweep, clamp diameter, computer mount, and integrated stem lengths.
Stems: length, angle, stack, clamp and steerer diameter.
Tyres: diameter, tyre system, tread pattern, TPI, width.
Frames: the old "Di2 compatible" checkbox is gone and replaced by a three-way shifting support field (electronic only, mechanical only, both), because a yes/no could not say what a mechanical-only frame is.
Units live in their own column now instead of being baked into the label, so a spec table can show "42 mm" without the label reading "Rim Depth (mm)".
UCI approval lists
The UCI publishes two registers: approved framesets and approved wheels. Both are now imported weekly and matched against our catalogue.
1802 frameset entries, 2539 wheel entries, 687 brands in total
195 of our parts currently carry a UCI Approved badge with their approval code
A matched approval is the only thing that makes a product UCI legal on this site. There used to be a "UCI legal" checkbox that anybody could tick, and it is gone. You can filter a category by UCI approval, and the approval code is shown on the part page.
Worth knowing: a product that disappears from a newer revision of the register is marked withdrawn, not deleted. A frame approved in 2022 was approved in 2022.
Mini pump bench tests
Zero Friction Cycling in Australia run a testing programme for electric mini pumps, with measured numbers over 125 charge cycles: air output per minute, degradation, cold weather impact, weight, volume, gauge accuracy. That data is now imported and assigned to the pumps in our catalogue, and the meta summary on a part page can cite it the same way it cites a video review or a forum thread.
18 results so far, 11 of them assigned to parts we hold. This is somebody else's testing and it is credited and linked as such.
Alternative frames by geometry
This started as a private tool and turned out to be the most useful thing I built this summer.
Take a frame you know, say a Canyon Endurace or a Cervélo Caledonia, and get the frames in our catalogue whose geometry is closest to it. The comparison runs on stack, reach, head and seat tube angle, chainstay, wheelbase, trail, BB drop, top tube length and slope, and tyre clearance, weighted so that stack and reach matter most. You can pick a specific size, so you get the match for your size rather than for the brand's size 56.
113 reference bikes from 24 western brands are in there, and 15700 comparisons are precomputed so the pages are instant.

It is not a claim that two frames ride the same. Geometry is geometry. But if you already know a bike fits you, it is a much better starting point than a spec table.
Creator pages, and discount codes
Two connected things.
Discount codes. Creator discount codes are read out of YouTube video descriptions automatically. There are currently 438 codes from 127 channels in the database. They show up in three places: on the brand's part pages, underneath the video that mentions them, and on the creator's own page. Codes are attributed to the creator who published them, with a link to the video, so you can see where a code came from and how old it is.
Creator pages. If you make cycling videos that we cover, you can have a page at
/youtubers/your-name with your videos, your discount codes, the brands you cover most, your
written articles, and up to a few videos you pin as highlights. You get to edit the intro text,
your links and the highlights yourself. Two of them to look at:
The Italian Cycling Vlog and
my own.
This is opt-in and it is off by default. If you are a YouTuber and you want your page set up, send me a message and I will get it going. There is no catch and nothing to pay, your codes are already in the database, the page just puts them somewhere useful.
If you would rather not appear at all, that also still works. One channel asked to be removed entirely and that was done the same day.
New tools in the directory
The bicycle tools directory is at 27 entries. New since May:
AiFitting (AiBiTiq) - bike fit from a video of yourself on the bike
RubberSideUp measured tyre diameter database - actual measured diameters, not the sidewall number, which is what you want for tyre pressure calculators and for circumference
Lambda Racing geometry simulator - overlay and play with frame geometry numbers
Framle
Small side note: Framle is a daily guessing game where you identify a frame from its outline. 115 frames from 45 brands are in it, there is a challenge mode with presets, and a history so you can play old ones.
It is a pet project and has nothing to do with the rest of the site. I built it because I wanted to find out whether I could actually tell frames apart. I can, mostly.
If you find something broken, or you have an idea for this site, mail me. I read all of it. No account needed to look around, but if you want to comment, rate a part or keep a build, you can create one for free.
