STI shifter sometimes doesn't catch in cooler weather

I've got a road bike with brake lever shifters, and it's developed a small problem with age: sometimes, the shifter doesn't catch the first time or two I push it. It'll move easily, with no resistance, since it's not actually pulling on the cable,…

Can I use a 9-speed shifter with a 8-speed cassette?

I'm looking into replacing shifters on my MTB. Currently I have 8-speed Shimano Alivio shifters - will 9-speed Deore or SLX shifters work? I do not care if one of the shifter's position will be unreachable. Later I may replace the cassette to 9…

Front Friction Shifter Problem

I have friction shifters and for some reason the front one gives me a bit of trouble. It tends to return to its most untensioned state. So say I want to shift to a higher gear, it will try to drop me back down to my lower gear. My guess is I might…

Servicing/fixing an Ultegra bar end shifter

After almost 15 years of flawless service my 8 speed Ultegra bar end shifter has suddenly stopped working. With the wire detached from the derailleur so there's no tension in it the lever now only moves through 5 clicks. If I switch it into friction…

Front shift cable clip (?) loose, where does it go?

On my 2021 Trek Domane SL5, the shift cable started to dangle freely a few days ago. It comes with what looks like a clip that's attached to it. I'm not quite sure where that clip is supposed to go. It doesn't really seem to fit well anywhere on the…

Reassemble my Shimano Deore XT shifter

It's an old 9 speed shifter bought in 2010 or so. It has been completely in bits and i have it all nicely back together, it operates "normally" for once shift only, doesn't reset and so only gives me 3 gears. I probably have the lug in…

Shifter only uses first 4 gears

I've got a Shimano trigger shifter on an 8 speed derailleur. It only allows me to use 4 of my 8 gears. I can adjust the derailleur so that it is the top 4 or the bottom 4, but the shifter just won't click through the rest. It clicks 3 times and then…

How to install i-spec shifters without the corresponding brake levers?

I bought a set of second hand Shimano M980 XTR shifters and some KCNC I-Spec Shifter Clamps. I have absolutely no idea how the two can work together. I would say "E" should slide into "A", but really not sure and I don’t know how to use the…

Old thumb shifter slips - can it be mended?

This bike is over 17 years old and not particularly high quality, but it does not make sense to replace the whole thing over one shifter. So I am looking to repair it if possible. I'm confident with most aspects of maintenance, but I've no idea what…

combining friction shifting with indexed components

I would like to combine friction shifting and a 7 speed freewheel with current Campy Chorus derailleurs. It seems to me that the way that friction shifting works would allow this combination, since all that happens is that tension on the cable…

5-speed shifter?

I bought a mountain bike for my daughter at a yard sale recently. It's not a high-end bike (a Huffy, but probably the walmart or academy sports variety), but it was very cheap (under $20) and effectively brand new... one of those "we bought her a…

Disassembling Shimano integrated gear shifters (brifters)

The up-shift lever (the long one) on my gear shifter for the front derailleur got stuck and now I'm looking for a way to disassemble it. Is there a way to do it without removing it from the handlebars?
