My question is: Is the power necessary to spin gear combinations that have the same gear RATIO, but are comprised of different sized cog/chainring pairs. For example a 44 CR and 36 big cog have a gear ratio of 1.2; and a 42 CR and a 32 big cog also have a 1.2 gear ration. Is the power necessary to spin these gear combos, assuming the same rider and rpm, different?

Are you sure? Unless I have done my maths wrong? (i) 44/36 = 1.22 BUT (ii) 42/32 = 1.31

A pretty technical question, Why don't electronic gears just use limit screws as reference for indexing? Cassettes have little to no difference in their gaps so why not? It would automatically adjust and they can just make it an option to do it manually.

Hi. Thank you for the explanation. Does that mean with an 11 cassette and a double chain set there are 22 gears. But then there is cross chaining and there are gear ratios duplicated. Is it possible to explain for example, small front to be used with 1 to 7 rear and large front with 5 to 11 rear. As this will help prevent cross chaining and duplication of gears. If this could be explained it would be helpful, thank you. Nice kickstand, hack or bodge.
@donovanvaz3289 Жыл бұрын
Totally agree. Is it why now they refer only to an 11 speed bike as opposed to how many gears it has? Whereas in the old days you'd say it was a 22 gear bike. But as you say, not all gears can be used.

@tommyjensen37503 жыл бұрын
As much as I appreciate you trying to explain it, it still leaves the question “which is right for me?” Now, I’m pretty set in my cycling, but for someone new, this only explaines gears, not what’s suitable. What I’m trying to say, is that for someone new, this doesn’t make them any wiser on what to ride, the rest of us already knew it. Might be worth making a video on how to choose gears instead. From my view, my fitness dictates the chain ring size, the terrain dictates my cassette. In mountains I want 11-32 cassette, on the flats a 12-25, to have enough spand on my highest and lowest gears. As for chainring sizes, fitness comes into the equation. Watts or w/kg if ascending comes into matter. That’s a straight forward calculation. You should do a video on that, selecting the right gears for you course.

Its simple. Masters cyclists and triathletes should just stick to compact or below that but pure ego gets in the way. We all know that most age groupers in triathlon and cycling thinks they are world tour pros. If you know you know.

Does it require the same effort to push the same ratio regardless of whether you use the big or small chain ring? It seems like I get more bang for my buck if I'm in the big ring?
@matthiaswuest72713 жыл бұрын
It should be the same, but depending on the specific gear ratio the chain line might be more efficient in the big ring. GCN did a video looking into this recently
@matthiaswuest72713 жыл бұрын
Also a smaller cog is marginally less efficient than a bigger cog, but I doubt that you'd be able to detect that (I know I can't)

I started using a cadence and a heart sensor with my bike comp, so far avg my cadence to 60 and select my hardest gear I can use without reducing my cadence or increasing my HR. Is this a good way to train and ride to improve? Or should I be focusing on increasing my cadence and using an easier gear for improvement.
@MrFoxmarine3 жыл бұрын
Usually a higher (85-95) cadence is preferred because it means less force is going through your joints and connective tissue, but if you don’t have any problems riding there then you can ride at your self selected cadence
@michaelsingh8433 жыл бұрын
@@MrFoxmarine I figured to play to my physical strength, I have enough muscle to mash a high gear. 60 cadence is comfortable, after some adaptation I will push the cadence to 65, then 70 and so on. I find the key is pedaling to a rhythm so there very little fluctuation in cadence. In a short period I noticed a considerable improvement and I'm no where near the fitness I should be.

if you need to get extrimal gear retions for mountains for example what is the best way to do this? set a cassette with 32t or 34t or set a inner chainring 34t?
@matthiaswuest72713 жыл бұрын
You could do both if you wanted the 1:1 gear ratio, but that's rarely needed. Probably better to go for the compact chainring setup and keep the smaller gear jumps with a standard cassette in the back

The most important gear on your bike is the rear wheel, but none of these geniuses ever take wheel size into consideration when calculating the gear ratios. This goes to show they are not really into bikes, but just trying to sell stuff.
