I've been asking for a 'report segment as bad version of another segment' feature for years...

@MyriadEventsSA Can't find any info online on the venue. What are the amenities like? Things to do for family / young kids while we slog it out on our bikes?

Is it the same socks or similar socks or the actual socks? 😜

Same bike (sort of), but that's a new bike yes.

Kent Main is not on a conti team. Even "domestic pro" would be a stretch of the word "pro" as his team has some product partnerships and minor support at best.

I'll take your word for it and assume the website needs updating... 🙂 "The 115km race will start outside Leipzig Farm about 500m before the infamous gravel section"

Challenging enough to be a talking point, easy enough and short enough to be manageable on your normal roadbike. Start at the gravel section, do it at neutral pace, then come back 90km later and do it at race pace before a fast 20km circuit to an uphill dragrace to the line.

No, doing Dirty DC and Tour de Worcester on Ceder weekend.

[gets popcorn]

Seems we'll start with an unenforced neutral on the gravel section again this year... 😆

Your first example is possible (although out of spec) without the extender, so maybe it helps that you are not asking too much from the extender...

I simply went with your suggestion on constant ss and BR to use your math to illustrate the direct relationship between bs and SR. The extreme of this is 1x where all the derailleur capacity is available for the cassette (BR == SR).

Reducing the SR has no effect on largest possible sprocket if you change BR (as recommended). Reducing the SR takes up more derailleur capacity if you keep BR the same size, so less capacity is left for cassette range. Why is this a hill you chose to die on?

DeCap - BR + ss = bs - SR You say all the left is constant, which implies if SR goes up then bs can go up. But you advised OP of the inverse relation, which simply isn't true, and you supplied the math to show it. And nothing you said in answer to OP's question was relevant to OP who posted a video where both rings were changed so that chainring contribution to derailleur capacity was unchanged. It's all about guide pulley clearance.

Lucky for me you both posted the incorrect argument and the math to prove yourself wrong. 🤷‍♂️

By chance the one gps recorded one or two fewer samples on entry (starting the clock late) and again on exit (stopped the clock early). It's all to do with how Strava decides you have started or finished a segment and your gps sampling rate. No sampling errors here.

Okay, obviously DeCap is constant, but you said that if you increase your SR you should decrease your largest sprocket, then posted math to justify it, but the math posted stated the inverse of what was said. Again you are now doubling down on it limiting the big sprocket, but your math (and in fact reality) is that larger small ring (all else equal) allows for a larger big sprocket.

And also, your math aint mathing First post said larger SR would reduce DeCap 😉

It's not recommended (sometimes not even possible) to go down to to such a small small ring without also reducing the big ring size, so I took BR-SR as mostly constant.

Why would this matter? This only affects chain length really. This generation derailleur did not support larger than 27t officially, probably mostly because those cassettes didn't exist back than. The only 27t cassette was a 12-27t, and if you wanted the 11t you had to take the 11-23t. The SS vs GS allowed for a larger jump in the chainrings. I'm guessing the guide pulley is actually capable of handling larger than 27t so with aftermarket options folks figured out it can clear a 32t without issue. Note that total capacity is 29 on the SS, so with an 11-32t you can only have 8 tooth difference up front (which you won't find anywhere). With GS the capacity is 37, so 34/50 or 36/52 or 39/53 should all work.

Very rarely is it only the cage design that is different. Most often the long cage version has a different derailleur body design too.

OP, what exactly are you trying to do on what generation derailleur with what cage length? Also, what's a roller arm?

And folks would see this somewhere and then promptly slap a 11-34t on a R8000-SS 🙈

I was chasing @Jbr after losing a bit of nerve on the technical descending just prior and being just out of contact. Was not paying attention and GPS alerts were muted... Disappointing for sure, and lesson learned!

After missing the right turn around km 80 my race was effectively over. Was nice to stop here for some treats. Not something I get to do often! 😀
