Great tip. Thanks!

Garmin claims 25 hours in day flash mode: www.garmin.com/en-US/p/550821#specs

@@Mamilian I just used the UT800 today for the first time, and it is great how bright it is in the daytime strobe mode. I will keep using it to see how long the battery lasts in daytime strobe, but it does not seem logical that it could last 25 hours, when the other modes do not last even half as long... I still think Garmin has a typo, but I will see...

@@mnewbro It's unlikely to be wrong, or really wrong. It makes sense given how much less energy it takes to pulse an LED for .5s vs continuously power that LED.

They are not compatible with current Shimano 4 bolt designs. They should work with any 5-bolt 110BCD crankset. Some of the older Shimano cranks used this format.

@@Mamilian Thx for your answer. In some Praxis video, they said their chainrings only work on their cranks, but I wasn't sure.

I bought it on eBay.

You're welcome?

Nope. I usually ride 4-6PSI on the fat bike.

Thanks for sharing your experience. I completely agree that there isn't a perfect system. I don't think single payer is perfect, but I do think it's better, and I think the data supports that stance. I hope the below explains my thinking around this topic in more detail. Insurance is a mechanism to spread risk. The bigger the pool in the insurance grouping, the lower the individual cost and risk. One difference b/w a single-payer run insurance scheme, and the multiple insurance providers we use in the US is scale; more scale nets lower individual cost and risk. The other major difference is one model is for-profit, the other is not (in application). For-profit companies have different incentives than not-for-profit. The number and size of the pools doesn't fundamentally change the underlying risk factors; people in high-risk categories exist either way. Currently, we're paying for these folks one of two ways. One, they have health insurance, so they are in a pool - everyone in that pool covers their risk. The other, is if they don't have health insurance, then they forgo routine (cheap, preventative) care, and only receive catastrophic care; which is expensive and difficult to schedule. This isn't efficient, we have to plan for higher peak than otherwise. Everyone who has health insurance in the US pays for the second approach through higher costs at hospitals/urgent care facilities/etc. That cost doesn't go away, it's just spread out differently. We're paying for high-risk people either way. There's no way to get around that without denying them catastrophic care. I don't think that's a choice that most people would opt for. With a single-payer scheme, everyone has insurance. Everyone can (or not) opt into the cheap, preventative care model. Which should save money, pain, and lives in the long term. The US has the highest (roughly double) per person healthcare cost versus comparable countries. Our for-profit model drives this difference. Conversely, health outcomes in the US are worse than other countries. I don't have great numbers here, but I suspect that wealthy people with good insurance have great outcomes, and everyone else the opposite. There are way (way) more not-wealthy people in the US. This would explain the data. I suspect that if we turned around the model, we would see fewer people in high-risk categories. I suspect that one of the reasons why our population is obese and has poor health outcomes (vs the rest of the developed world) is because we don't make it cheap and easy to get routine care, and the basic health literacy that comes with that. If you're guaranteed two GP checks a year where you're educated about healthy behaviors and mildly shamed for poor decision making, we might see a change in outcomes.

I used a #15 O ring that I bought at Home Depot.

Probably going to depend a lot on how hard you're working and how well insulated your arms are. I've ridden these with light gloves at -3 F and no gloves in the 20s. But, I generally keep my HR in Z2+ when I'm riding the fat bike. Riding at a low intensity would net a different result. Also generally bring a couple pairs of gloves with me, so I can start the ride with a medium weight and swap for a light set when I warm up.

@@Mamilianyour reply is helpful so thank you! Based on your response, I think these should work well for me. 45NRTH has them on sale currently for 60% off so going to try them out.

I have not. TBH, I don't get the allure. I'd rather have a spoke that has a little more compliance and isn't hard to find/replace when it breaks.

Thanks. It's attached to the GoPro mount on the underside of my out-front computer mount. I talk through the setup here - ua-cam.com/video/VkqRZv780fo/v-deo.html.

In a wired setup, you can always add more ports with junction boxes.

This is a good resource for IW/tire size compatibility: www.wtb.com/pages/tire-rim-fit-chart. 3 bar (~43.5PSI) would be totally fine as long as the tire is also rated for that pressure level.

It has a HG hub. Should be able to put up to a 12 speed Shimano HG compatible cassette on it.

I have a love/hate relationship with Xert. LOVE the load tracking and ability to slice data. Not a fan of the workout recommendations. Sometimes they are perfect, other times, I think Xert is trying to kill me :).

Load tracking is definitely a good one, but I've been really impressed for years with their derivation of TP and LTP. And yeah, I don't use many of their stock or generated workouts. I'm usually doing "zone 2" paced by DFAa numbers, or some workouts in Xert from the few years I had a coach (who's long been a supporter, and critic, of Xert).

@@Zyzzyx42 I totally forgot about the derived TP/LTP. That is very useful as well. I also really like their workout player for doing indoor training. It's one of the best I've found.

This is a more complex topic that I intentionally presented in a simplified way. Fat burn is not missing from the model as presented however, it is an aspect of the calories "that come off the body". I discuss some thoughts around fat adaptation in the article I mentioned (link is in the description). The TL;DR is that unless you are riding at low intensity, running off fat is not a viable strategy. If it were, we wouldn't "bonk". Some amount of your caloric debt will be covered with fat at most intensity levels. The lower the intensity, the more fat can be used to pay that debt. The body prefers glucose however. It is the quickest, and most efficient way to create the ATP your muscles need to activate. The more glucose, and things that can be easily converted to glucose (i.e. fructose), you can intake the less fat the body needs to burn. Lowering your fat requirement increases the available intensity level. This video is targeted at racing but the nutritional discussion is applicable to any ride where performance is an aspect of "success". There are many different way to define "success"; that will pivot around your goals. The approach to fueling will vary depending on what those goals are. If you're going on a 5 hour Z2 ride, with the intent to maximize fat burn, you would not want to fuel the same as a race. But, if you were going on a 5 hour Z2 ride, where the intent is to hold a more consistent power level, and be in a place where doing it again the next day, you will want to run a higher carb mix. This is probably a topic that I need to dive into further in a future video. Nutrition is a lever that we can pull. How we pull it depends on the goals for the ride, and the next ride.

The mechanism is a little unintuitive. The lever rotates separately from the axle. Turn in the axle in the open position, then close the lever to test the tightness. If it's not snug, open again and tight some more, then test. When you get to a good place, you can move the lever to the desired place without tightening the axle. Then close it to snug everything up. Hope that helps.

@@Mamilian thanks so much for the quick reply and support! Verry much appreciated! The problem I have is that the lever is too tight, so I need to untighten it, but I can't figure out how. Reading your advise, am I right to conclude that I cannot simply first snugly turn in the axle to the right snuglieness and afterwards tighten the lever? But I need to balance the tightness of the axle with the tightness of the lever? If so, this is the only way I am able to snugly tighten the lever, but this seems wrong, because now the axle is not fitted as tightly as needed.

Thanks! I appreciate the "for you young guys" :D.

How would you clamp the normal post in the seat tube? I don't see how that could work; I have a Speed Concept. Even if that was an option, that's a lot of work to clamp the bike. Especially if you have Di2 with the battery in the seat post. FWIW, the easy way to work on a TT bike if you can't clamp the seat post, is to hang it from the saddle. Most TT saddles can be gently clamped as well - if you need more stability.

@@Mamilian not a lot of work. Most seatposts come in three sizes. You just remove the aero and install regular. No seat will be moved so reinstall at the same height and your off. Now it won’t work with anything other than round post holes of course.

@@tasaman I'm not aware of any modern TT bikes that have a round post. Do you have an e.g.? If you have Di2, it would be disconnection the battery, making sure the cables didn't get stuck in the bike when you stick in alternate seatpost, then getting the tape out to ensure that you put it all back together correctly. There are easier options: ua-cam.com/video/hvtiEphcbpU/v-deo.html

I will be fighting for the DFL award :D

If it's a medium cage (the model number is printed on the mech), you're good to go. Likely that you'll need to add a link or two to the chain.

The purpose of "rear shelf", as I understand it, is to align the rings during installation and likely also provides some level of support to the ring during use, assisting the chainring bolt so it is not the only load bearing element. I'm not sure I understand what you're asking to be compared. I provided the measurements for the respective spiders in each video. The most important number there is likely to be the width of tab where the rings are mounted (this sets the distance b/w the rings when they are installed), as this will impact shifting performance. Here we can see that the Croder spider is much closer to the spider on the Specialized Power Crank.

@@Mamilian yes, i can agree that the most important measurement is the thickness of mounting tabs.

How would you test that? With your hands? Testing component failure modes is very difficult without specialist equipment. I'm not going to build a rig that does that, not when there are alternatives that aren't designed poorly. Just to be clear, if you're cool putting that in your bike, I have no problem with that. You get to have your preferences and I get you have mine. I prefer to use things that are well designed and less likely to fail.

@@Mamilian on a bike of course, you have to pedal a bit, and you will see if it works or not ....

You're suggesting I should test a product that I have concerns around the safety and function on the bike? This isn't the kind of thing that is going to fail immediately. It's the kind of thing that will fail after use, and during use. If it fails at the wrong time, you could crash. I would rather spend the extra money to just get something that I am comfortable with. Since you commented on the other video, you've seen the difference between these spiders. I don't understand why we are having this discussion.

@@Mamilian yes, i suggest testing them before making those "statements"

If by "those statements" you mean characterizing a product which I believe to be poorly designed and potentially unsafe as poorly designed and potentially unsafe. I don't think that I need to put myself at risk to voice that opinion, an opinion that I checked with an engineer. You are free to disagree. You're free to do whatever you want. It is mind-blowing that having seen the difference between this spider and the Coder spider we're continuing to have this discussion. But hey, it is totally fine with me if you want to risk yourself over a few $. 👍

I haven't used the S-Works version. Word has it they were having issues. My new fav tire is the Schwalbe G-One RS.

@@Mamilian oh RS its also in my list, 40? 45? Easy rolling but to easy flat? Thanks again

@@gabrielmarias972 I have the 35 & 45 sizes. Generally race on the 45. Fast, comfortable, great all-purpose tire.
