Also you can wreck the auto focus and stability motors on your phone camera from the constant vibrations

yeah but the examples they give for those are lower cc and electric motors I can't see it being in issue cycling unless you are constantly riding washboard or rumble strips even then quad lock includes little vibration absorbing ring

amenenema posted:Perhaps you've heard of this new thing called a "gravel bike" Gravel bikes that hum with vibrations at frequencies that are perceptible as musical tones? Seriously, this isn't an issue for bicycling. It's an issue for high-RPM vibrations over long periods of time. You're not doing that on a bike. The rattles you feel on a bike as you go over gravel might feel like a lot when compared to, say, riding on pavement. But, they are nothing compared to 3000+ RPM vibrations on a motorcycle. It's not the hard rattling of bumpy terrain that messes up the phone's camera; it's the constant buzzy vibrations that you only get with engines. Just because a lot of something causes a specific issue, that doesn't mean that way less of that thing will cause a similar issue. Of course, maybe there is a lot of evidence of people's phones being messed up due to bicycling? I went looking many moons ago, and the only documented issues I could find were all related to motorcycles.

My anecdote: the focus motors died in my pixel 3, which I did use on a bike handlebar mount quite a bit, but I can't prove it was the bike that did it in and some quick googling about it says that phone might have a fragile focus system so  .

I imagine the problem is that it's impractical to do broader testing for every single model. That'd be the only way to prove the issue one way or another. You'd have to have like 100 phones, a test cycle broken into 4-5 phases, and some sort of rig like this but with the same forces acting on each phone:

I could definitely see phone cameras dying after being subjected to fast group rides and road races here. Watch this clip from the 1:45 mark and keep in mind this is the slow Master’s 35+ category 3 and 4 race. P/1/2 would probably be going 3mph faster. The vibrations are too much for the GoPro’s EIS to handle. https://youtu.be/1lrpx4kU6v4

If you want to use a phone mount you just need to run the fattest tires with the most supple, paper thin casing you can afford I had an automatic Seiko watch that broke from wearing it while riding. That was from a triple triangle aluminum frame with a 22mm tire on the front riding on chip-seal roads though

I'm looking to buy a gravel bike. There's a cross bike on super sale that comes with a 1x 40 up front and a standard road cassette in the back. Given the choice, would you guys go with XPLR (10-44) or go with a full mullet in the back? FWIW, I live in Colorado.

There’s a reason why gravel bikes became their own category and why everybody didn’t suddenly just start riding cyclocross bikes, and it’s not just because -marketing bullshit- Cyclocross bikes are built mainly for cyclocross racing, and while a ton of them can make perfectly serviceable road/gravel bikes a lot of them are built with mud clearance/shoulder carrying in mind and things like comfort, straight line stability, etc take a distant second.

amenenema posted:The article literally warns of this. You mean the article you linked to that only describes motor vehicles? Let's forget the fact that it's talking about motor vehicles, which is a fact we shouldn't forget, but for the sake of argument. The lower vibration metric they discuss on mopeds and scooters is amplitude, not frequency. The Source You Quoted posted:What if your motorcycle doesn’t vibrate very much? "Attaching your iPhone to vehicles with small-volume or electric engines, such as mopeds and scooters, may lead to comparatively lower-amplitude vibrations, but if you do so a vibration dampening mount is recommended to lessen the risk of damage to your iPhone." Low amplitude vs. high amplitude is the difference between loud and quiet. Low frequency vs. high frequency is the difference between low and high pitch. Apple's warning here is that less powerful motors might have less amplitude, but the frequency will be in a similar range, and because of that, you should use vibration dampening when attaching your phone to the handlebars of a motor vehicle. These kinds of sustained, steady frequency vibrations are something you don't get on a bicycle until you stick a motor on it. This is one of the articles I read months ago when I was looking into this, by the way. I'm aware of what it actually says, and most other articles I found about this were related to this article, either citing it directly, or clearly containing the exact same information.

I'm trying to learn a bit more about bike fit and computer vision for a new job. What's the cheapest way to hold my bikes stationary so I can record myself pedaling and (eventually) analyze the fit? Have a mix of boost and non-boost bikes so would like something that can adapt to either.

A 1X drivetrain with a 40 in the front and a road cassette in the back doesn't sound adequate for a gravel bike at least for the hills where I live. I converted an old CX bike into a 'gravel bike', it has a road compact at the front (50/34) and used to have a road cassette at the back (11-28). I slapped a mtb derailleur and cassette on the back (11-36) and that's barely enough for a steep gravel hill. It also doesn't have clearance for any tire larger than 40mm (some CX bikes I've seen can't even fit a 40) and the geometry is basically a road bike so it's super nervous and hard work descending on rough gravel roads.

Yeah I’ve ridden a gravel bike with 40/10-44 and it’s been fine. Was more curious if the additional mountain bike 52 was super useful or not. The geometry thing is what I’m more worried about, especially since I’m looking at doing 100-200 mile races on this thing. Geometry in a 56 seems very close to an Aspero/crux in a 54, which are “real” gravel bikes though.

I don't race so I appreciate the slacker geo of a "gravel adventure" bike compared to a CX or gravel race bike. I run with a 46/34 crank & 11-32 cassette and it's mostly good but I wouldn't say no to a 34 cog either. On slick 38s it makes for a really nice road+/light dirt bike that's quick and comfy all day. If I were really getting after the gnarly & steep gravel it'd be out of it's element in both tires and gearing, though.

IME CX bikes tend to have short stays, high BBs, pretty quick steering and limited tire clearances. Get a bike without those things and you'll be fine, and if it's nominally a CX bike WGAF.

Aspero is marketed more as a gravel race bike, I'd say. As for 1x in Colorado -- I think it depends on what this bike does for you and fits in with your other bikes. Are you racing CX? Is it doubling as your road bike? Is this your second drop bar bike? I live around Boulder and run a 44x11-44 and it's fine, but if it were my road bike too, I'd go 2x almost surely. When on pavement, I spend a good bit of time in the smaller cogs. 1:1 gearing has gotten me up Magnolia here in town without much fuss. I run 52/36 front gearing on my road bike for perspective. Only you can answer how low your gearing needs to be because it's based on fitness and terrain. If you're running 40t up front, I probably wouldn't go mullet. This year we saw the mullet gets more appealing when you're running a 46-50t front ring where the hard gears are hard and the mullet gives you the climbing range.

Also on gravel vs. CX differences -- real CX bike do make a different. There's a reason a sponsored Santa Cruz rider was racing on a 2 generation old frame this year.

The Aspero is a cool bike, slightly higher and slacked out road geo and can take two different wheel sizes and loads of clearance. The BB on the R5CX is proper CX height among a lot of other differences. I think it looks freaking great too.

vikingstrike posted:Aspero is marketed more as a gravel race bike, I'd say. Nah, I have a separate road bike. This would primarily be a bike for gravel (ie fire roads, stuff around Boulder) and for races. I'm planning on doing Unbound 200 in 2025, so I want something that can take me through that. numberoneposter posted:The R5-CX is totally different geo than the Aspero? My friend has an R5-CX, it's a great looking bike, he loves it. Are you sure? I'm looking at the R5-CX in a 56, Aspero-5 in a 54. Geometry Geeks seems to put them within a cm on pretty much everything. The standover/BB height seem to be the main differences.
