How to Replace a Broken Spoke
Demonstrates a single spoke removal and installation.
If you break a spoke on your wheel, the best thing to do is stop riding until you can get it repaired. However, sometimes you simply have to keep riding, in which case you can keep the broken spoke out of the way by twisting it around an adjacent spoke.
To replace the damaged spoke, first remove your wheel and then the tire, tube and rim tape. Then remove both ends of the damaged spoke and nipple. Spokes usually break either at the nipple or at the hub flange. If it’s a rear wheel, you’ll have to remove the cassette or freewheel first.
Insert the new spoke and gently flex it into place, using the other spokes as a guide. When installed properly, the spoke pattern should be consistent all the way around the wheel.
I personally recommend using linseed oil to lubricate the nipple threads before threading the nipple on to the spoke using a screwdriver or nipple driver.
Gently pre-bend the new spoke by pushing down on it at the hub flange, and then tighten the nipple using a spoke wrench until it has the same tension as the rest of the wheel. Check this by plucking the middle of the other spokes on the same side and then compare them to the sound of the new spoke. Now you can true the wheel as demonstrated in the last tutorial, and re-install your rim tape and tire.

Hello, I’ve got an old set of square taper FSA tempo cranks (2x) that I want to swap from a single speed 120 OLD bike to a 1x10 135mm OLD one. Any tips on how to calculate the spindle width for correct chain line? I can’t find anything for that model on the manufacturers website, and i don’t think measuring the one on the single speed will work with the different chain line....Read more
Awhile back, I was able to hack a 7 speed freehub body and get an additional speed out of it by using a 9 speed cassette with the narrower spacing. Note that these older freehub bodies are 7 speed exclusive. They do not typically have the space to fit a larger cassette on them. To do this, I took a 9 Speed Dura Ace 11-23 cassette and I simply removed the final combination cog from the back, then...Read more
Ciao. I know that some bike riders overexaggerate the 'cleaning part' and wash (or spray) their bikes at least once a week. I know, it's mandatory after a muddy trail ride. But I'm thinkging more about daily commuters. It gets dusty here and there, but how long is too long without a shower for a bike? For a bike that rides almost every day....Read more

Looking for advice. I have repeated problems with my D-lock sticking. I've used standard light bike oil which then leaks all over my hands when I handle the lock. I have some 3-in-one PTFE spray: would that be better?...Read more
Hi, So I bought a used Schwinn Meridian sight unseen online auction for $59 & drove 8 hours round trip to get it. It appears to be brand new actually. When I got it home, the next day I checked out my score. When I sat on it and pressed on the pedals, they moved but the bike did not. I inspected the bike and realized that whoever put this trike together, forgot to put what appears to be ...Read more
Hi everyone! I hope you're enjoying a great start to 2023. I'm curious to hear your go-to method for getting a chain truly clean. I don't mean, just looks shiny or is good enough for a quick clean after a ride. I want to know what you do when you want to get every last morsel of ground-up, link-destroying, roller-eating, tooth-gnashing crud out of your chain. The Best Chain-Cleaning Recipe Ever?...Read more
In the past I have had a lot of punctures. When they happened, I patched the tube, but the holes in the tire were so small, they did not need patching. After many more kilometers, rubber started coming away around two of the holes in the tire, exposing the chords. If I did not do anything, a rock could cut the chords, destroying the tire. I wanted to get more use out of the tire. I cut patches fr...Read more
Obviously, this doesn't speak for them all, but they certainly might fit! And not even just barely (as suggested by some sources), but with a lot of room to play with. This is another GT Tempest frame that I recently purchased. It's originally a 26" alloy touring bike. As you can see, there's lots of head room, and plenty of clearance to increase the tire size up to probably 38c—maybe even 40c....Read more

I replaced the chain ring on my bike recently. The new one I bought had AVANTI written on the cranks in large letters. I expected, with a name like Avanti, it would be good quality. It had steel internals, and plastic on the outside of the cranks. When I went to accelerate quickly, the crank broke. It turns out the steel in the middle is very thin, thin enough for the crank to break when accelera...Read more
