My bike goes up one gear at a time, but down two: is this normal?

On or off road, but especially off road, it is desirable to be able to shift down more than one gear at a time to deal with abrupt changes in gradient and avoid being stuck in too a high a gear and ...

How do I remove a severely stripped/rounded-off Allen/hex head bolt?

I can suggest three methods. The mounting clamp has a gap. You can use a thin saw to split the bolt there. It might scratch the clamp, but with careful action, the saw blade will not touch the ...

Can a counterfeit Shimano chain be used on an authentic Shimano drivetrain?

You can normally use chains from other legitimate vendors, be it SRAM or KMC or something else. You do not need to use Shimano™® chains only. But no-one can tell you whether your chain is of ...

What is this stamped metal piece that fell out of a new hydraulic shifter?

Providing the 7900 is the same, I’m sure it is but someone more qualified can chip in if it’s different. How did it fall out ? Shimano have a proper tool for removing them. Info from here Fawkes

Should a 10 speed shifter only click 9 times?

Imagine you have only two cogs in the rear. You start on the smaller one. If you downshift once (down means larger cog, up means smaller one), you're now on the bigger cog. That was one click. You had ...

Can a counterfeit Shimano chain be used on an authentic Shimano drivetrain?

The main problem is quality, in terms of dimensions and variance. If you think its an 11 speed chain but someone has just repackaged some 10 speed chain, then there will be issues. Likewise, if it ...

Can you use two different shifters (eg. Left-Tiagra,Right-105) on the same cockpit/handlebar?

The shifters on your left and right side don’t have to match. They can even be from completely different manufacturers. On road bikes it can be problematic because when riding “on the hoods” (the ...

Broken 105 shifter in fall, cause and is repair possible?

Sadly, all I have is bad news. It's not a quality control issue. It may not have felt like much of a crash but that lever was hit hard. There is no way to fix it. The plastic shell is part of the ...

Shifter cable ruptured near the inner end in ST-R7020 - usual defect?

The cable turns a double right angle in quite a small space. It's a very common failure on all the 11speed shifters from 9000/6800 onwards. The "solution" is to change the right hand cable ...

Does my shifter need to be replaced after crash damage?

Based on your description and photo, probably not. As long as it still functions correctly. That is the key. So, if it still works and is not broken/cracked, go ahead and use it. Keep an eye on it ...

Can I swap a gravel wheel with 1x10 cassette for a new road wheel with 1x12?

No, your derailleur/shifter is indexed for 10 speeds, not 12 (spacing between cogs is smaller in 12-speed cassettes).

No, it's set up the right way. (In fact, because of the way the front and rear gear systems work, it's essentially impossible to set them up backwards: you'd have to re-engineer the whole system.) ...
