I tested leather saddles mainly from Brooks but also the 2010 Lepper Voyager, and as a comparison the classic Selle San Marco Rolls. Also analysis of various issues with some of the saddles I used, correpondence with manufacturers, experiments, and a number of modifications that I made to leather saddles.
Read here what pressure you can really achieve, not the fairy tale numbers that most manufacturers tell you!
Feb. 2018: I finally got round to further disassembling of the Quicker pro. I had to because mine didn't work any more. There is 1 big flaw in the Quicker pro: The steel fixing clip in the top. It will corrode... It was completely gone (rusted away) in mine. The junk from that made the inner tube with pressure display opaque too. This clip can be replaced by a stainless steel M3 washer and a stainless M3 nut that you can screw onto the plastic post... Pictures and disassembly instructions to come.
Aug. 2017: There are problems with the Birzman Apogee pump head, it just doesn't work on all Presta valves and Birzman doesn't seem to find it necessary to respond to emails... (still no reply, dd. 2018-11-20...). So my recommendation is back to the Quicker pro, but that is hard to find if you want one. I could buy a batch from Quickex again, but they don't sell quickly. And they are also not perfect though less problematic than the Birzman (the only real issue is the missing dirt cap). Are you interested in acquiring a Quicker pro? If so email me. The new all-black version as shown on their site looks nice! Due to all these problems the same reader who also found that the Birzman doesn't work on Schwalbe Presta inner tubes, said "Appears there are no satisfactory pumps available; may as well go back to solid tyres!". Thanks for that, I laughed :)
See my smaller scope tests here and perhaps interesting my commentary about stuff I saw on the internet and on youtube about bicycle stuff.
My test bike was stolen Thursday evening 9 Aug. 2018, in NL/Leimuiden. If you see it in NL let the police know and send me a message...
Maybe it's on the way to Poland, or some such destination, but in case it stays in NL, if you see it let the police know and send me a message...
Nederlands: Cannondale fiets, type Vintage, zwart, schijfremmen, Dit is mijn testfiets, opvallend door 2 verschillende pedalen voor testen, dito 2 verschillende handvatten, 3x9 versnellingen, bijna alles is zwart, zadelpen: Descendant, zadel: Brooks b17 imperial (uitsparing in het midden) zwart, linker handvat kurk, rechter handvat leer bruin, fietscomputer: O-synce, achterdrager vervangen: was Cannondale's eigen merk (maar die was gebroken), is nu Atranvelo, Stuureinden van Ergotec, ligstuur (alleen de arm-steunen) van Ergotec, koplamp: Herrmans H-one S (met plakband waarop V2 geschreven staat, dit is de versie met neutraal wit licht), achterlamp Spanninga Solo. Continental achterband, voorband is een Compass Barlow pass 38mm vouwband (door een lezer van mijn site gestuurd om te testen/vergelijken)
English: Cannondale bicycle, type Vintage, zwart, disc brakes. This is my test bike used the last 2 years for testing lighting and pedals and grips etc. And so it sticks out by having 2 different pedals for testing, ditto 2 different grips, left grip cork, right grip leather (brown), 3x9 gears, almost everything is black, seat post: Descendant (contrary to the pics), saddle: Brooks b17 Imperial (so with cutout in the middle) in black, bike computer: O-synce, rear rack: Atranvelo (I had to replace the original rack which was Cannondale's own brand, which broke), bar ends from Ergotec, aero bar (but only the arm rests mounted) from Ergotec, headlamps: Herrmans H-one S (with tape on which I wrote V2, this is the 2nd version of the H-one S with neutral white light), taillamp Spanninga Solo. Continental rear tyre 42-622, front tyre is a Compass Barlow pass 38mm folding tyre (sent to me for testing by a reader of my site)
Numbers on the frame: 57 1 086.128 (so: 571086128) / UN..571 (can't quite make it out)

Each donation is appreciated, but even better is to buy a Brooks saddle or bicycle lighting parts!
Changes from 6 Nov. 2017:
- Nov. 2017: 1. Removal (well, moved to here, and I have no intention to update these test) of all smaller sections such as about minitools and gears etc. as I will go back to basics, 2. Removal of all Dutch/German pages: I have not kept the pages in Dutch in sync anyway, as it costs too much work and the sales side does not support putting in a lot of work. There were only a few pages in German. 3. Separate the bicycle lighting reviews from the overviews and technical analysis. The reviews are to be linked to as 'examples' to show problems in lights/dynamos in the analysis section.
- In 2018 I will mostly stop selling bicycle stuff (only continuing with some Brooks saddles and modifications), as there is just not enough appreciation for what I do, i.e. the sales are far too low for the effort and guidance that I give in reviews. So I will have to do something else, and possibly work with a manufacturer, though the bike industry is really reluctant for any change and not interested in suggestions for improvements or even new ideas as is shown in what has been produced the last 6 years in dynamos and headlights, which is not impressive and barely improving over what we had in 2011. That means my interest stops, unless finally some manufacturer wants to make real improvements.
The method: How to do tests the right way, including how to determine what is important for tests
The following is only of interest if you are interested in understanding people, I explain a lot of the behaviour of people related to discussions on forums, newsgroups etc.
- The truth and the method. Here I analyse some misconceptions and tell you about what it means to make a good review, what do you need to measure (if anything), and what it means to be scientific. Being scientific is not about doing measurements, but about the way you analyse what needs to be analysed... You don't need to measure the exact temperature of a room to know whether it's too hot, too cold, or just right for you. Same with vibrations by dynamo hubs... A few topics: Do you ride faster with smaller wheels? Do you ride faster with a lighter bike? Does dynamo efficiency really influence your speed? The answer is no, or not significantly at best in case of dynamos, but many people think it is a big influence. Countering misconceptions about these and other topics is a big part of the process of doing proper reviews!
