With these rings you could have 48/32 on 110 bcd 5 arm cranks https://absoluteblack.cc/oval-sub-compact-chainrings-48-32-for-110-5-bcd/

Disturbingly GRX 600 is probably at least as good as any other option, apart from the looks and the weight maybe. And only a hundred euros with 46/30.

Yeah, durability might be a more accurate term for the ability of an ultra racer to set off at a steady moderate power and keep that up for days or weeks. Though their ass and hands etc. have to be durable in different ways too, so maybe muscular durability would be a better wording. Though it would also need to be aerobic durability or whatever.
Fatigue resistance has already been used for what seems to be the same thing they mean here and would seem to describe it better.

I assume it refers to Andrew Huberman and his Huberman lab podcast, they've mentioned the positive neurological effects of creatine as a sidenote in several episodes. https://open.spotify.com/episode/4FU8oakQNGK5ciOtpUCTB9?si=p0BC0GiKT_yxsAMEV8yRsQ

Nice. Is the cassette a Rotor or the ZTTO they sell in Aliexpress or are there others?

Yeah, but one might have trouble finding a 12s 42t cassette, the usual suspects don't make them. But it does seem they do exist and more might appear later.

My whole groupset was worn out, wouldn't have changed it just to get the new stuff. It does seem very similar to the 11s GRX, no huge improvements. The mechanical levers are similar. The tiny increase in brakepad clearance is nice, though the old ones were fine too. I think the jockey wheels are bigger, we'll see how long they last. The RD that's meant to be used with 2x is rated to be used with a 36t cassette, so that's a bit more than the stated max used to be. But there's less cassettes available with the about 40 teeth one might want for riding a loaded bike in the mountains. At least for the traditional HG freehub. I don't know if anyone has tried what the actual max might be yet. There are 45t MTB cassettes that would be interesting to try to fit, but that's for the microspline. And I think Rotor had something that could fit. The 2x stuff is made for the HG and 1x for the microspline. But I'm fine with the 36.

Yep, 10% more. Not much of a difference.

the new increased pad clearance is what I want.

The new GRX brakes are said to have slightly more clearance than the 11 speed generation.
I just replaced my old RX4s with the new GRX and they do seem to be quieter, but I haven't used them in rain yet.

Weird. I've got a Oneup V2 dropper on my Stanton too and it's been good. Have used it for about a year. It's a shorter 150mm and an older Sherpa made of 853, don't need as much clamp force maybe.

Osprey apparently, from 1994 and rather nice indeed. https://www.lfgss.com/conversations/366818/?offset=100

I suppose I have a soft spot for these as I had one of the cheaper Bianchis from the same years as a kid and my dad had one of the fancier ones, SL470 I think from 1996, which is now my commuter, posted on the previous page. There was a local shop selling them and so there were lots of Bianchi MTBs about. Mine has got studded tyres on it now for the winter and the commute today in -13℃ was pleasant enough to prefer to ride to the office instead of working from home.

There's a link to a 1996 Bianchi catalogue here, there's an Osprey too: https://www.retrobike.co.uk/threads/bianchi-catalogues-from-96-98.451294/

That's how I've got mine too.

I had some pain at the base of my thumbs too, years ago, when I had a bar with only a few degrees of sweep. I changed that to one with 11° and the pain disappeared so I assume that was it.

.

Hylexs and bar end shifters do make sense, more space for handlebar bag when there's no brifters flapping about.

It was indeed probably the lighter and more durable solution with the materials they had in the 30's-70's, the usual way to build bikes was with lugs that were made for horizontal toptubes so to have bars comfortably high with a short quill stem the toptube had to be high.
I think Jan Heine said somewhere that he feels it's better for how the frame flexes.
So yes, mostly aesthetics. And bigger framebags.

For further amusement, here's Jan Heine's bike for Paris-Brest-Paris, fit like they used to be in the 40's

And some random bike by J.P. Weigle

Kind of like these.

Yeah, more space for a frame bag and I like the handling of the longer reach and wheelbase, unless it's a road race bike. Though I might be biased because I like the look of old french fit randonneur bikes and I have relatively short legs so my bikes are kind of like that in any case.

Well yes, and the few others I know that have done more than one ride up there recommend taking a full suspension or a fatbike. One had a rim and the rear triangle of a full suspension bike crack there. But it would be possible to travel the distance with a rigid bike too, it would just be slower and harder, more walking. I did do a trip in a different part of Lapland on a gravelbike, 650b 2.2" and 48 mm. Had fun but a hardtail would have been better. There's pictures of that on the first page.

I made a randonneur bag. Pretty pleased with it. My friend Eetu made the rack.

@Sealclub just with my fingers, the same way. I didn't change them that much though, but a small change can be done. I've installed Berthouds on six bikes and have adjusted all of them a bit.
Here's the 60mm 650b pair on a bike with 650b wheels

And here they are on 26x2.3", maybe not quite perfect on either but that would be because of not caring about the looks enough.

Yeah, my comment was meant as a reply to @Sealclub , to say that in my experience Berthouds can be tweaked the same way as the other metal mudguards. They do indeed make a 60mm 650b size that is a good fit with about 48 mm tyres, though depending on how close to the tyre you install them you may want to adjust the radius slightly, as with any mudguard.

I have re-radiused 650b Berthouds to fit 26" and a 700c set slightly to fit another bike too. Just need to be careful to not dent the middle unintentionally. I have also dented the sides to fit between the stays, but I did it with pliers and the result is not that pretty.

Kind of similar to the racks clamped to the headtube on Kronans and some old dutch bikes.
