Interesting that the recall inspection procedure doesn’t call for inspecting the NDS arm for Ultegra. https://youtu.be/mKMKsbts3t8?si=cQiH_KIPFrfQC7bV I didn’t know that those arms were hollow forged, not bonded.

So many great details on this  Heliosicle posted:Yeah I'm not sure if ankling is my problem really, but I do have tight hips from sitting most of the day which the cranks could help with. Will order some and see how it goes. I switched the cranks a few weeks ago, put the saddle up by the 7.5mm, and promptly had a load of muscle strain behind my knees from over-extension. After a bit of trial and error I'm now comfortable at about 1mm over my previous saddle height, so no change basically. Not entirely sure why, but this article https://bikedynamics.co.uk/FitGuidecranks.htm suggests that if your position is already good little-to-no change should be needed. Anyway, its been a great change so far. My hips feel so much more comfortable and I can get low without kneeing myself or my hips feeling like they're disconnecting from the pedal stroke at the top.

Oh, I do get that above the knee strain a lot too.. what's usually the culprit for that, bike fit wise? Everything else seems comfy, but when I try to put power down I feel a lot of weird twinges and pain there if I'm not super careful with keeping my muscles around the knee tense and supportive of it

If it’s the back, sounds like your saddle might be too high, but impossible to say really without seeing you. Easy to try dropping it 10mm or so and going for a ride.

I had really bad knee pain that made me worry about continuing to be able to ride maybe 5+ years ago when I was training 10+ hours a week. I did a lot of stretching back then too and loosening my IT worked to a point. I ended up going with shorter cranks and I haven't had similar issues since. My legs still get super tight sometimes, I need to start stretching again, but this time round it goes all the way down my leg and makes my toes so stiff I can barely move them for a day until they loosen up. Also I'm getting old.

Compatible with tubeless and 47c tires I would in retrospect avoid GRX for my own use case. I just don't understand the point of making a proprietary chainring and then not making a bunch of sizes. I would understand if they were trying to make money by being the only place selling different rings, but shimano only offers two sizes. Wolftooth makes a few GRX asymmetric 110 BCD rings but they've been sold out of the largest and smallest sizes for as long as I've been checking. They still have the shimano-offered sizes 40/42 in stock because lol of course but if you want anything else its going to be a while and another $80.

The range of commonly available crank sizes is weirdly narrow. If we assume that hundred and seventy five millimetre cranks are appropriate for a person five foot eleven inches in height (one point eight metres), cranks of one hundred and sixty‐five millimetres would be appropriate for someone who is five foot seven inches (one point seven metres). I’m not saying that even shorter cranks are the answer to all fit troubles, but I am saying that they shouldn’t be so niche. One in four American men is shorter than five foot seven inches and nine in ten American women are. Or maybe short people are actually using perfect cranks, and it is tall people who could make good use of longer ones. In either event, if it’s likely that a random sample of thirty people will have the extremes differing by more than twenty percent in height, why is it that the longest cranks in the shop are only six percent longer than the shortest?

Platystemon posted:The range of commonly available crank sizes is weirdly narrow. There are huge assumptions in your argument. Variations in height don’t necessitate different crank lengths, and neither do leg lengths. There is a very small range which is about right for almost all humans, the first modern geared bicycles got it pretty much right. I suspect a default of 170 suits more people than the 175 my bikes all came with, and I’d say that bigger cranks than that should be special order if anything. You can compare to road bike handlebar widths; 99% of men should probably be on a 40cm or 38cm bar by modern fitting standards, as the shoulder joint widths (end of collarbone) just don’t vary that much, even in vastly different sized people. People use narrower bars for aero reasons, but few men need 36cm or below. Bikes above a medium all come with 42, 44cm bars by default that almost noone needs, though some people want them because they’re used to it or want to be like the pros from 1980s.

Speaking of handlebar width, I had my first issue-free ride in what feels like ages yesterday, which I attribute to switching to (even) narrower bars. I went down to the 36 cm version of these last week to try and finally fix the median nerve issues I've had in my left hand for the last year or so (going down from 40 cm wide bars without a flare, with a shoulder width of 40-41 cm but somewhat valgus elbows) and it worked! My fingers still start tingling after ~30-40 minutes, but switching to the drops for a few minutes makes the feeling subside entirely and yesterday the tingling didn't even return after 4-5 hours in the saddle. So finally no (real) saddle soreness, no numbness in my left hand, no back pain! What's more is it was a ~300 TSS ride with 6:08 elapsed time of which 5:41 was spent moving, so I'm optimistic about my fit for the first time in a long time, maybe even forever  anyway, more actual ride reports to come soon (  I know...) from when I climbed the Cormet de Roselend and the Col de la Loze a while back. I've been meaning to post about those for months, but some personal stuff came up

Vando posted:Because correct crank length does not scale linearly with height? Ignoring the significant fact that terrain features are sized irrespective of anthropometry, why wouldn’t cranks be a linear function of leg proportions and thus roughly with height? I know there’s that study that shows humans seem very adaptable to power output over varied crank length, but I think it’s more a business decision than anything else to ask a person a head shorter than be to run an extreme hip angle on a crank 2.5mm shorter than mine.

It's definitely a business decision but I was reading OP as asking why we don't see 155mm and 180mm cranks, I guess if the question is 'why are pretty much all new bikes shipping with 172.5mm cranks, maybe 170mm or 175mm if you pick XS or XL' then yes that particular window is unacceptably narrow and crank length should be available as a buyer specced option way more often.

No, because optimal crank length is not proportional to height. Remember that when you change crank length you're not changing crank length alone, you're most likely modifying at least saddle height at the same time to compensate. It's about power delivery more than sizing on the bike.

Good ride yesterday. Trying to kind of squeeze in those last big ones as the days get shorter. We started about 20min east of town along the blackfoot river and then went north from there to do a gravel loop. Gold creek after a bit of climbing  After the first 8mi or so we passed a gate and were on forest roads closed to motorized use for awhile  the rattlesnake mountains, just north of town, where I usually ride  Mineral is the closest one, I've been up there and there's a lookout. Behind it and to the right is stuart peak. I go to the wilderness boundary just below the top fairly often but have only hiked up from there once or twice. wore my new mumu jersey  Then after awhile you're descending the other side looking at the swan mountains  water refill and snacks at placid lake (there's a water fountain and real bathrooms and such in the state park and campground)  Then climbing back out of there but on a different road to make a loop The swans again and our lake  Looking northwest we can see the missions now too  Both the missions and swans run north-south in a line, south of glacier np. To the west of the missions is the flathead valley, to the east of the swans is the bob marshall wilderness. Seeley-swan valley between the two. Plenty of grizzly bears around but we didn't see any. Descending back down  After a short climb over a ridge we were back in gold creek and on the way to the cars  (mineral peak again in the center). Just over 70mi, just under 7k feet. A+ ride would do again https://www.strava.com/activities/9914835652 jamal fucked around with this message at 22:36 on Sep 25, 2023 |

Btw good quality CX secondary brake levers are fuckin dope, 10/10 would recommend folks trying them on their gravel bike if they like doing easier MTB/CX single tracks. We have a wonderful river valley trail network here, and being able to be on the tops for more control while still having your hands on the brakes and hit some easy MTB trails is great.

good bits;

It's about power delivery more than sizing on the bike. Changing saddle height to account for crank length is a given; i don’t think it negates the intuition of proportional sizing. I would argue comfort is more important than power, especially if the power band is really broad and not peaky like that study showed.

Shadowhand00 posted:Good consistency! What's the route you're taking? this is the gist of it (I'll also edit my post): I've kept 95% the same route these past 3 months so I'm decently comfortable with it now. I've been tweaking bits of it to try and avoid conflict with cars and signaled intersections (to different degrees of success) this time I tried to bike up Townsend instead of Market, which reduced the amount of time I have to wait for downtown traffic in exchange for a dicey conflict with the big bus stop next to the train station  also avoided Pier 39 and Fisherman's Wharf, which swapped conflicts with tourist drivers and cobblestones for a big hill. kinda threw off my ability to climb the Fort Mason hill afterwards  and finally I took Strava's advice and took a bike path in Corte Madera instead of biking next to the mall. that was a straight up improvement biking from Sausalito to the bridge, I've decided always always bike up the back way from Fort Baker even though you end up losing half your elevation along the way. the road is way less treacherous and SUVs won't murder you while honking my only gripe with the route is that it has lots of hills on the return journey coming back after you're more than 75km in. there's no real way around it imo unless you finish up by biking laps up and down the Embarcadero corona familiar fucked around with this message at 00:19 on Sep 26, 2023 |

I dunno, Market is crap. I prefer taking 17th eastward from the Mission, then Mariposa down to the stadiums and going up from there. Granted, it does mean more cars but the pavement is better. Or just keep the city miles to a minimum and ride out to Lucas Valley, Nicasio, or Tam.

A bit too many car-centric roads on your route for my taste. If you’re interested in some routes that push out a little farther north, there’re several that go through Fairfax and put you either at China camp or Point Reyes. Can link some if you’re interested. Obviously, coming back from the bridge, there will be small 300 foot hills (usually about 4-5) through the route, but they’re great for pushing that workout to the next step

I've found paradise loop to be alright if I were to go further out I think I'd pack more stuff and it would turn into more of a trip than a workout, but that's not a bad thing is there such a thing as AAA for cyclists? e; they literally do AAA for cyclists, interesting corona familiar fucked around with this message at 06:13 on Sep 26, 2023 |
