Hach, immer wieder schön, wenn Aktionen von Rechten nach hinten losgehen und über die AfD gelacht werden kann. Dieser parlamentarische Arm des Rechtsterrorismus darf sich gerne selbst abschaffen.
That was one hard ride yesterday. Today my legs are totally empty and it took me three mugs of coffee to feel somewhat alive. Still, happy with myself.
Working on my Bedrock Sandals tan.
A JSON editor recommendation by a colleague and friend panned out and that’s going to allow me to move post from my old Ghost blog to Micro.blog in a sensible pace, correcting broken image links, etc. Looking forward to having my old content here again.
Every time I watch DS9, I keep being impressed by the portrayal of a single-father/son duo (Ben & Jake Sisko). It’s loving, affactionate, sensible, realisitic, and positive. Just beautiful to witness.
Neat review of the Paul Klamper disc brake calipers.
I considered these a while back for my gravel bike rebuild but there weren’t enough comprehensive reviews for me to take the plunge. I trust Russ.

Since getting back in to cycling, I‘ve learned a lot about bike maintenance by watching the instructional videos by Calvin Jones of Park Tool. Today‘s lesson: „How to Clean Hydraulic Disc Brake Pistons“. Braking response is much smoother now.
Bin grad im Kapitel „Highschool“ in Alice Hasters Buch angelangt. Puh, diese Passage:
»Hey Germany«, sagte der Junge neben mir. Das sollte mein neuer Spitzname werden: Germany. Da musste ich erst einmal über den Atlantik fliegen, um als deutsch angesehen zu werden.
The Trump regime is inexcusably and openly tolerating hundreds of thousands of U.S. Americans dying and suffering due to COVID-19. I have a strong feeling that if they are voted out of office, investigations may eventually lead to verdicts of treason against Trump his apparatus.
Was that pride I heard in Andy’s (@hellobuglers) voice when Alice (@aliterative) made that Messy joke on #TheLastPost yesterday? Loved the episode. Such good entertainment. #HAGOW
Warning, this may be a bit wordy and nerdy.
I have been researching drivetrain options again—don‘t judge me—because I found myself wanting a bit more evenly and tightly spaced gears on both my road bike and my gravel bike.
The area I moved to a while back (southern Black Forest, Germany) is an absolute dream for cyclists: I can climb to my heart‘s content either on- or off- road and when I just want to go fast on the flat, a short trip into the wiiide Rhine valley and it‘s go-time – yes, I went there.
On Panthor, my road bike, I presently have a 1× (single chainring) setup using a 36-tooth chainring and a 12-speed 9–46 e*thirteen TRS+ 2nd gen cassette. For the 11 gear shifts, I get an average gear ratio change of 13.8%. The gear ratio in the lowest gear is 0.78 and in the highest gear it‘s 4.0.1
On Battle Cat, my gravel bike, it’s a 1× setup with a 32-tooth chainring on the front and a 11-speed 9–39 e*thirteen XCX cassette on the back. That gives me a solid 0.82 gear ratio on the bottom end of the spectrum and 3.55 on the top end, as well as 10 gear changes with an average gear ratio change of 13.6%.
Digging into some good combinations of cassette and chain rings, I had two sets of requirements 1. A closer grouping of the gears on the road bike is desirable but with at least one climbing gear with a gear ratio below 1. 2. A low climbing gear on the gravel bike is a must given the steep and quite technical terrain I‘m riding more and more often but I also want fairly evenly spaced gears throughout the range, to tackle longer rides across varied terrain more comfortably.
There‘s an incredible amount of choice in the market for realising what I wanted on both bikes but in all cases I found out that a 2× (double chainring) setup was probably the only way to get there.
Most cyclists know or have heard that a 2×11 setup typically offers 14 unique gears. This can vary depending on the choice of chainrings and cassette in the back. I‘ve compared a lot of cassettes and chainring combinations using a nifty little online gear calculation tool by Jürgen Berkemeier; everything from the e*thirteen and Shimano cassettes I have at home to options from SRAM, Sunrace, Garbaruk, KCNC, etc.
Similarly, I looked at various double chainring options, ranging from insane 53/38 to the 46/36 I still have on my Rotor 3D30 crankset to 46/30. Most of those combinations when paired with almost any cassette end up giving me 14 unique gears, a few give me 15 and even fewer only 13. Interestingly, depending on the difference in teeth between the big and small chainrings, I‘ve seen cassette + double-chainrings combinations where the shift from big to small or small to big chainring (and compensating in the rear) results in a 2%–4% gear ratio increase. I‘d consider this barely usable, which means that these combinations really only offer 14 instead of 15 or 13 instead of 14 unique and usable gears.
46/30 chainrings are the only ones I found that, paired with the right cassette in the back, end up with 15 proper, unique gears and a change from the small to the big front ring (again while compensating 3 gears on the cassette), results in an actually usable jump of 7%–9%.
I checked other variations of 16-tooth difference chainrings but none seemed to work out with such a high gear ratio increase.2
It gets even funnier looking at the cassettes. Only two cassettes I‘ve found, have cog size spacing that results in 15 proper gears: * Shimano CS-R8000 11–32 * Shimano CS-M8000 11–40
I‘m going back to 2× on both my bikes. – GASP!
Panthor is going to receive a 46/30 chainring coupled with the 11–32 cassette. This gets me a gear ratio of 0.9375 in the lowest and 4.18 in the highest gear and and average gear ratio change of 10.11%, a reduction of ~ 3.6%. This average value may not sound like too much but looking at the gear ratio changes across the current 11 and soon 14 shifts, it‘s substantially closer gearing that‘ll give me a much more consistent cadence.
Battle Cat will also get a 46/30 chainring connected to a 12–40 cassette.3 The low gear will offer a ratio of 0.75—*WOOOOO! Insane climbs here I come!*—and the high gear is going to have a value of 3.83, which is plenty. The average gear ratio value will be ~ 11% (down from 13.6%) across 14 gear changes (up from 10).
I’m not sure how long this is going to stick, if I like the setups for riding, and to a lesser degree from a visual perspective – vanity in cycling is a thing, y‘know.
Thankfully I still have a set of Ultegra R8000 brake shifters and an Ultegra R800 front derailleur at home. The remaining parts like the new chainrings for both bikes were fairly easily found. The Rotor 46/30 direct-mount chainrings are already here and the Easton Gravel Rings, the left GRX brake shifter and the second front derailleur should be here by the end of the week.
Looking forward to the tinkering and trying these two new setups.
That’s just as realisitic as any stock market predictors we see out there.
Looks like I’ve managed to snag the 46/30 Easton Gravel Rings double chainring from an online shop. They appear sold out pretty much everywhere. Might get them tomorrow.
Clip-on aero bars or lightweight toast carrier? You decide.
Second mug of coffee for the day? ✅
Ok, I may have (wilfully) underestimated how much harder a switch from a 32- to a 36-tooth (oval) chainring would make climbing the local hills but it was still a really nice gravel ride.

Road derailleurs, including the RD-RX800 clutch derailleur:
Add 2–4 additional rivets from the reference rivet.
Add 4–6 additional rivets from the reference rivet.
I really hope they’re going to remaster and release Deep Space Nine in HD. It’s jarring to go from TNG to DS9 and watch it in SD. Especially because it’s the best series of them all.
While taking the dogs out for a walk, I went past a house where someone was practicing a brass instrument. After playing through the scale forwards and backwards a few times, they went straight to the Imperial March and I was barely able to control my desire to clap.
The oval Garbaruk chainring I ordered is likely going to arrive tomorrow. Much earlier than expected. Looking forward to it.
In the process of setting up my second CR 1600 Spline wheel set tubeless, I ran into the issue of the wheels not holding pressure again. The tubeless valves that DT Swiss provide with their wheels, or rather the gasket used, simply doesn’t seal well in those rims (the middle and right gaskets in the picture below).
For this wheel set I bought a set of Muc-Off Tubeless Presta Valves, which also came with three different types of gaskets. Being hopeful, I tried using the gasket that looked similar to the one supplied by DT Swiss and it was a failure, like last time. The tyres/wheels wouldn’t hold air well and my workshop smelled like Muc-Off sealant all day.
The solution was to switch to the biggest gasket supplied with the valves (pictured left). Even with the valve screw tightened down with less force, I got a proper seal immediately and the next morning the tyre pressure gauge showed the same 4.8 Bar I pumped the tyres up to.
Yesterday I took the bike out for a ride and everything worked perfectly with no pressure loss whatsoever.
Apart from this issue with getting a good tubeless valve seal, the wheel set(s) have been incredible. Considering the amount of abuse I subject one of them to, it’s surprising that it still runs perfectly true. Really good value for money. Fitting most tyres (tubeless or tubed) is a breeze.
Went for a short and quick bike ride. Came home mildly exhausted and satisfied. Right as I got out of the shower the endorphin kick set in. WHOA!
