CORONAVIRUS UPDATE ON ME AND MY SITUATION: I am currently in Mexico in a city called Aguascalientes. I arrived here after about a week without the internet to find that country borders closing around me. I had a few days to book a flight back home (Australia) but just couldn't bring myself to do it. While going home was perhaps the wisest decision, right now my eyes are so damn focussed on CYCLING all the way to Alaska. I don't really know what that means for the rest of the year. The situation could get so much worse, especially here in Mexico where people are not even getting tested for COVID-19 and are definitely not taking social isolation seriously. While the situation is so crazy and uncertain - know that I am very content here and am always focusing on the positives. In a lot of ways, travelling the WORLD by myself on my bicycle is literally the perfect preparation for weathering out this storm. My plan over the next 3-6 months is to focus 100% on making videos for you. That means my video content will be much more frequent (probably weekly), with a focus on bike tech and travel tips. I will also conduct 2-5 day adventures around the region I'm staying in, carrying all of my own food - and will, of course, share these adventures with you. As a result of needing extra support over the coming months, I've changed the rewards on my Patreon. This is to hopefully attract more supporters to actually make my filmmaking viable. I'm now offering your name in the credits of my documentary films, postcards from exotic parts of the world, access to the books I've written and private video calls to chat about everything bike gear and travel. www.patreon.com/cyclingabout If any of these rewards entice you, please know that your support will be going towards new camera gear (microphones + an action camera), as well as freeing up much more of my personal time. All the best from Mexico, Alee

Excellent explanation. Subscribed! (Industry vet of 30 years). I recently went your budget build route and it works. I wanted to experiment with a long TT, slakish head angle (71 deg. from memory) without committing time and cost of building a new frame. Looked at modern flat bar geometry and went ah-ha! Bought an Avanti INC 2 Urban in XL, and fitted drop bars, TRP Hylex brakes (this is a Gates Carbon / Alfine 8 bike) and 700*40 Kenda Flitridge Pro rubber. It's a heavy beast, but handles exactly how I want. Will replicate the frame in steel for an Alfine 11 I have sitting in the shed, and my poor man's Stoater will be born. One other benefit. When using a traditional HB bag, the bag sits behind the front contact patch. This is why French constructeurs preferred long TT, slack head, & short stems on their randonneurs.

I accidentally rode some steep single track descents and regret trying a drop, fearing for my life. In those moments I wished for a dropper, straight handlebars and a more upright position. It never crossed my mind why anyone would want drop bars there.

Does the more-mass-means-better-cornering-grip-math really check out for bikes with so little Suspension? Of course a tyre with more weight on it will generate more grip (this relation is oftentimes less than linear, i think) But the front wheel has a leverage advantage vs the center of mass, because it is further away from the turning point (rear contact path). So a longer front-end will have less grip, but it will also need less grip due to the better leverage to turn the bike. An analogy could be found in automotive suspension design, where more front axle weight is associated with understeering and not oversteering as the more-mass-means-more-grip-math would suggest.
@Cyclingabout4 жыл бұрын
It definitely checks out. The best way to try for yourself is to ride a long john or bakfiets-style cargo bike without a load, on a loose surface. It's incredibly easy to understeer the bike, but as soon as you increase the load on the front tyre (add weight to the cargo box), it will have ample front end grip.

@Cyclingabout3 жыл бұрын
It's to minimise the wheelbase length, maximise the front centre length (in small sizes) and better match the overall steering characteristics around the stem length. Big bikes have longer stems which call for a faster steering geometry achieved with a steeper HTA. Small bikes use slower steering geometries (slacker HTA) but have shorter stems. Personally, I'm not racing in a peloton on my road bike so I don't need a short wheelbase to slot through tight gaps. I'd prefer to have a longer top tube, shorter stem, slacker HTA, longer fork rake and longer chainstays. In fact, most of my recent road bikes have just been gravel/cyclocross bikes with road tyres, which have allowed me to achieve these exact parameters!
@MrTeff9993 жыл бұрын
@@Cyclingabout It seems to me that when frame sizes of a given model have different HTAs, each one will handle differently. This is because the ratio of height to wheelbase increases. Although lengthening the stem can slow the steering inputs on steeper frames, it doesn't change the fact that the endo point is made worse. Also, the longer stem just adds to the problem by moving the center of gravity forward. I've ridden with 6'11" Bill Walton who has a custom made titanium road bike made by Bill Holland. It is very tall but the wheelbase seems almost comically short. I've always feared that one day he would do a terrible endo. In any case, when a reviewer says he loves the way a particular bike carves corners, I'm never sure if that holds true for all frame sizes of that model. Keep up the good work.

Great video and detailing the geo and why it was done, you mentioned using a Salsa Journeyman as a budget replacement. I'd also like to suggest the current generation Salsa Fargo even though it does have a shorter toptube and reach, it makes up for much of that with the much slacker headtube and taller front end. It creates a very balanced bike for both onroad and off, it also carries weight really well. Also the tire clearance becomes more and more important with both the difficulty of the offroad riding you are doing (more grip) and with long distance offroad comfort (bigger tires mean less pressure which gives a more comfortable stable ride.
@Cyclingabout4 жыл бұрын
The Fargo is within 31-44mm in wheelbase length across all frame sizes, so it's going to be similarly stable bike with slightly more front weight bias. I chose the Journeyman because it is much closer in terms of bike fit, weight and max tyre size - more of a "gravel" bike if you like.

Bad idea, here is why: None of the "gravel" terrain shown in this 15 minute video was ANYWHERE NEAR the kind of trail that warrants such "progressive" geometry (you actually had to use some MTB footage showing a Dale Scalpel to illustrate the point about going down descents). This thing has a 66 deg head angle, while my Scott Spark has a 68 deg head angle. But the Spark is used to ride on terrain that's easily 20 times more technical and steeper than the "gravel" roads shown (just ask Nino Schurter). Somewhere in the middle, you started talking about cargo weight distribution. Wait, are we talking about touring bikes or gravel bikes? Plus, if you would ever need to ride down big drops or rocks, why would you use a rigid fork and a narrow bar? A gravel bike with a dropper post? Why do you need a dropper post when you don't even have a suspension fork? If you are tackling a pro line in Whistler, get a Nomad or Spectral. What does "progressive" even mean anyway? Allowing trans-people in women's bathrooms??? In my mind, there is no "progressive", just "suitable". Why would an Arabian want to have quarter horse legs?
@Cyclingabout4 жыл бұрын
-The trail does not need to be super steep to warrant a slack head tube angle. The head tube angle and fork rake make the wheelbase longer, which lowers your CoM, even on a 3% decline. The result is more bike stability. Not to mention, the endo angle is larger, which means if you hit a rock or water bar on the road, it's harder to go over the bars. - I mention cargo capacity because lots of folks use gravel bikes for bikepacking and touring. - This bike is not designed for drops or rocks, it's designed for gravel roads. - "Progressive" is just a word that the industry uses to refer to the trend of longer, lower and slacker. - A dropper post allows you to lower your CoM on steep descents.

@@Cyclingabout Thanks for your response. I read it very carefully, but I am still struggling to see how my points are addressed. With respect to COM, it has very little to do with wheel base, as it's only limited by pedal strikes. If you lower your COM, your pedals will be closer to the ground, you hit a rock, you fall. In fact, longer wheel base makes pedal strikes more likely for a given terrain (coz there is more opening space between the two wheels). In addition, is "more stability" always better? Why not a 50 degree head tube then? Or what the heck, how about 40 degree HTA? So road bike and CX bike geometries w HTA of 71-74 degrees over the past 100 years all got it wrong? Bike designers all neglected the "endo angle" for a 100 years? If one is really worried about hitting big rocks, maybe one should get a suspension fork? Also "The trail does not need to be super steep ... A dropper post allows you to lower your CoM on steep descents." Again my point is, some of the features on this bike are those that would suit a typical Enduro course, while other features can't even handle moderate offroad terrain (such as rigid fork). In my opinion, it's an interesting experiment, but the designer really hasn't thought it through.
@Cyclingabout4 жыл бұрын
- When you make a wheelbase longer, it effectively lowers your centre of mass (nothing to do with the BB height) which will make a bike more stable. In combination with a dropper post, which allows you to drop your CoM even further, there is no doubt that the Chamois Hagar is THE most stable gravel bike for descending. - Over rocks, you're correct, the pedals would effectively be closer to the rock when you pivot over it. But the Chamois Hagar is a gravel bike and not at all intended to be used on rocky terrain - especially with the 50mm max tyre widths. - Why not 40/50 degrees? It affects the steering speed too much. There is not a stem length, nor bar width which would make it work well. - Road/CX bikes are built for a different purpose, so the geometry is always going to be different. A CX bike needs to make lots of sharp turns at low speeds with lots of weight over the front tyre, and the high trail and long front centre of the Chamois Hagar would hinder that. - Enduro/XC bikes are also built for a different purpose, so there is no need to compare the geometries and features of these bikes. It's important for us to assess how 66.6 degrees with 57mm trail on a rigid bike will work *specifically* on dirt roads. - Don't get me wrong, I agree that 66.6-degree HTAs offer lots of shortcomings for most gravel riding speeds and terrain, but it DOES make sense for high-speed gravel riding, in particular.

All this is a mind field to me as I’m trying to understand more... very interesting bike to talk about...it helps when comparing to other bikes xx

@@carlaarden5891 I don't think you need to be a technical MTB rider to appreciate the benefits of this bike. Anyone will do better on fast gravel descents with a longer wheelbase, slower steering and a larger endo angle. But this geometry definitely has downsides in different riding situations. You can design bikes to not shake at speed with the right frame geometry, even weight distribution and an appropriately stiff frame and fork. But typically, I recommend people move their heavier items *from* the front of the bike as it makes your bike so much less agile. With all other things equal, smaller wheels have less gyroscopic effect and they increase the steering speed (less trail). You could say that comparatively, they are less stable on fast descents but more agile for slow-speed manoeuvres.

Frames that are designed around short stems already reduce the adjustability of the frame. This is problem pronounces if you are a short rider or have short upper body. It really does seem that many new bikes (almost all of the mtbs) are designed that way. Making me, a 5' 9" tall person, to buy small or very small frames and use short stems or there is not even small enough frame available! I would appreciate that the frames were designed around longer stems so there will be more room for different people to adjust. I am frustrated by this. I've decided never again to buy another mtb. Luckily I am not much into mtbing.. but they are not the only bikes that are designed looong.
@K1989L4 жыл бұрын
Oh yeah and bars over 60cm often cause me pain so if the steering is fast with a short stem then I just need to deal with that. I always prefer much narrower bars than 60cm. So todays bike fads aren't making me any favours.

My bike is a Nicolai/Geometron G1 it's an enduro bike it has long chainstay slack headangle. You are not completely right when it comes to chainstay length, shorter the rider shorter the chain stays should be, I am 181cm and my bike has 455 mm chainstay. Many brands do the mistake of having same chainstay for all sizes, this means the balance points are different. Shorter chainstay makes the bike more noble, easier throw around, fishtail, but for some bikes short chainstay makes sense, like a dirt jump bike, bike trails bike, there steep headangle also make sense, but for all other mountainbiking it does not, of course not evry bike has to be like a Geometron G1. But some years ago many brands went with as short as possible chainstay, which was silly.

@@Cyclingabout on a Mountainbike the slack headangle is great, yes wheel changes angle of the bike while turning but it, does not a fight to keep it going straight, or 5urn it where I want it to, my fork has 44mm offset, headtube angle is at 62 deg, i have 33mm stem, 800mm bar, reach is 515mm i use mid foot position on Catalyst Pedals, I have saddle tip above bb, so it's a modern setup, modern bike, the seating position effects the balance points, or body language on the bike. My bike is a good mix. But I have tried a kids fat bike once, I know it was way too small for me I am an adult that bike was 24inch wheels, 😁 but it was a fight to keep it going straight, once you turned it required alot of force to turn it, it was a Diamant fatbike, that thing was so heavy I could barely lift front end and it was stuck to the ground when jumping, I could not, of course emabye with some practice I could do it but a kid should not suffer on a bike like that, I am not sure what they did but steering was the worst I have ever tried, but even for the kid who rode it the issue was the same, even a bmx handled better. And that's twitchy and scary. I guess that's what you get for budget bike. 😁 They got it all wrong. 🙄 My bike is not that. Many brands were late to the geometry game. And some are still catching up. But I went for a å frame set that was all the way there, where nothing had to be tweaked. 😊 But kids bike with strange steering or geometry, sizing is still common, but Nicolay could make the perfect bike, they did for a kid in UK. Same frame as me same geo, just for a kid. 👌
