Why is there nearly no 1x road bikes?

It starts to appear on the high-end range, and is common for some very specific applications (time trial for example). A commonly heard critic of 1x transmissions is that there are not enough steps to ...

Why is there nearly no 1x road bikes?

I’m going to state things a bit differently from the other answers. On performance road bikes, you want to have small steps between at least the major gears and a wide range. Going 1x with even 12 ...

Do teams change gearing depending on the Tour De France stage?

Pros can and do change gearing for any reason they want to - terrain, rain, wind, phase of the moon. It wouldn't even surprise me if they change gears based on inputs from doctors/sports ...

Is the mechanism that holds a bike to a specific gear in the lever that I use to change the gear or in the derailleur?

Yes, there is a pawl or similar mechanism in every indexed shifter that will not let the derailleur move once you have shifted. Whatever that mechanism is, it seems to have broken in your shifter. ...

Why is there nearly no 1x road bikes?

The motivation for 1x came from frame designers, not riders. MTB soft tail frames are extremely crowded around the bottom bracket. Suspension pivots need to strong and close to the crank. Removing the ...

Why is there nearly no 1x road bikes?

Unlike some innovations, electronic shifting seemed to take off faster on road bikes. That can be set up to allow the simplicity of sequential shifting that's inherent to 1x,but with more ratios. MTBs ...

Alternative gear ratio newbie question: Am I doing a mistake for this commuter?

Even with your current setup, you could be spending more time in the middle of the cassette and dealing with less total drivetrain wear by using the 44 more. So part of the answer is going to deal ...

Choosing a gear ratio on 20" vs 24" BMX that creates the same "feel"

You don't need trial and error and you don't need a chart, you need math. (Chainring teeth / sprocket teeth) × tire outside diameter = gear inches Rollout is just gear inches multiplied by π. Tire ...

Yes, they have choice. All three component groups you mentioned have a range of different chainring and cassette options and nothing in the rules prevents using components from a different ...

Is the mechanism that holds a bike to a specific gear in the lever that I use to change the gear or in the derailleur?

Indeed, there is usually a mechanism in the shifter that holds a cable in position. That cable keeps the derailleur in the right gear. If this mechanism is broken, the cable slides back to the most ...

Can a Rivendell Silver 38x24 crankset be used with a Dura-Ace 11-28 cassette?

Your cassette doesn't care what size your chainrings are, although those are remarkably small chainrings for a road bike. Is that possibly a triple missing its big ring? The number of sprockets on ...

Gates Belt Drive+Rohloff - What rear sprocket do I need to help me get up hills and mountains better?

With the existing 50T chainring and 19T cog your gearing ranges from 19.8 gear inches to 104.2 gear inches (assuming 622 wheels) So you're essentially loosing about a gear at the top end and gaining a ...

Alternative gear ratio newbie question: Am I doing a mistake for this commuter?

I would suggest keeping the 32t middle chainring (replacing if worn) and using an 11-28 9-speed cassette to get the result you seek. The chainring should have ramps to work with the other 22 and 44 ...

Why is there nearly no 1x road bikes?

It's really a marketing question. Salesmen haven't figured out a way to hype 1x. You do find 1x on work road bikes—city bikes and folding bikes (or time trial bikes for that matter)—just not on play ...

Chain drops when shifting up a gear at the front?

I am guessing it drops to the outside of the largest chainring when going from medium to large ring, in which case it sounds like your high limit screw is set too loose. If this is not the case, ...

1x10 vs 1x12 for green-blue, and perhaps a bit of single-black-diamond trails

It doesn't matter. If you don't ride competitively, it's not a problem to not be at the most optimum ratio, or even lacking range. Intermediate steps are less critical on trails than on road/gravel (...

Alternative gear ratio newbie question: Am I doing a mistake for this commuter?

You seem to be relying heavily upon 32t. Why not just keep 11-28 and go 1x with 36t? I had this exact setup for a year in a flat city like yours, and was very comfortable with close ratios and ...

Shimano 105 - Shifter Internal Lever Broken

If the entire lever remains in good condition, and just one part broke, it's commendable that you're trying to fix it rather than to just ditch it and replace. The last few releases of Shimano 105 are:...

Chain drops when shifting up a gear at the front?

The chain is dropping into the gap between the chainrings. The gap should not be big enough for the chain to drop into. At the factory something didn't go quite right. It is a chainring spacing ...

Why is there nearly no 1x road bikes?

Two words: efficiency and weight. Road bikes are ridden fast. To go fast, you need high gearing. You can obtain high gearing by either a very small sprocket in the rear or a very big chainring in the ...

Is the mechanism that holds a bike to a specific gear in the lever that I use to change the gear or in the derailleur?

It's possible that the cable just needs to be tightened. Over time, the cables can stretch. Look for a barrel adjuster like this where the cable exits the shifter, or maybe somewhere else along the ...
