14. 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.
Hi, Does anybody know the name of the 2 bolts that keep the chain tensioned on a fixed rear wheel. One of mine has snapped whilst undoing it to remove the rear wheel. Cheers Alan.... Read more >>
Hello, I'm new to the forum, and I don't understand much in bikes. I changed my tube (rear wheel) the other day, and when trying to put the wheel back on the bike, the quick release skewer won't fit in the hub\axle. It feels like something is stuck inside the hub. I went to a professional bike store, they tried hammering the skewer in, but it didn't help. They want me to change a wheel. What do i do? Thanks, Yedidya... Read more >>

Hi all, I'm disassembling and cleaning out my old SunTour freewheel, it had got so gummy the ratcheting wasn't happening. Once everything's clean and ready to re-assemble, will it be allright to use the same grease I already have for my motorcycle axles? It's an automotive product called "Industrial Moly EP Grease," "...an NLGI No. 2 grease containing molybdenum disulfide..." its listed applications include "Automotive Chassis, Wheel Bearings, Universal Joints." I live quite a ways from a bike shop, so it would be very convenient to be able to use this stuff. But of course I don't want to have... Read more >>
Hey all, One of the washers on my Pashley has worn out. More specifically the teeth have, and it's causing the wheel to go out of alignment when I sit on the bike as it slips. (Or so I believe, I'm quite new to this) I have a picture of the washer (http://i.imgur.com/gCrSzlU.jpg), does anyone know where I'd be able to purchase a replacement in the UK? I've looked on google but I'm having difficulty finding the specific type of washer as I don't really know what it's called. Thanks in advance!... Read more >>
I have a very old Dahon California folding bike with a 3-speed Sturmey Archer hub. I need to replace the rear wheel inner tube. I looked all over the internet, but can't find instructions for this. Everything is too new! If I take the nut off the side with out the chain, can I just ease the wheel off? Is there a way to release the chain that I can't find? I would really appreciate any advise, as I would prefer to do it myself, not take it to a store! I think it dates from about 1983.... Read more >>
Hi, On Sunday I bought a new bike. My friend has a half pipe in his back yard so i learned to ride that and i am pretty good at it. Yesterday after just riding around regularly i start to feel that my cranks catch in a certain spot. I take off the sprocket thinking it had something to do with my cranks. i twist the chain wheel on the back hub and i found that it was catching. I put the cranks back on and i start to ride around thinking maybe it was just a new bike thing and i had to break it in. After riding a little i start to here a pop sound every time i pedal. I don't know what to do. Sho... Read more >>
Hi, i ordered a Aluminum rimset and i have to specify the Spoke hole diameter im having the wheels built on Formula Th-50 hubs that take 13G 2.3 mm spokes, so the holes on the Rims must match ?

I finally upgraded my wheels to something stronger for my 235lbs. I was previously on Bontrager SSR's and they felt so flimsy and I hated them. I bought a set of Velocity deep V's w/ 32 spoes and 105 hubs online. I swapped my old 9 sp cassette onto my new wheels which i was told were a drop in for my old wheels (spacing included). I installed them but they sit totally crooked when seated all the way down into the rear dropouts. I can loosen the the quick release and shift it so it aligns in the middle of the brake pads but when seated all the way down, it's totally crooked in the brake pads. m... Read more >>

Hello, I changed the skewer on my back wheel, and now it jumps nearly out of the frame when I move the pedal. Any advice? The issue is definitely me because it happened with the same skewer on another bike. Last time I ended up putting the quick release skewer back on and having my bike repair shop change it. Now that I know for sure it's me, I want to figure this out. The front wheel isn't a problem. The skewer has a special end on one side that only loosens with a special key. The issue, in part, may be that it needs to be tighter, but I remember getting it as tight as I could last ti... Read more >>
Does anyone know of a better bearing for the rear axle of a 3 wheel bike. The bearings keep going bad and ruining the axle. We have used the standard bearings from the bike shop. This is an older Miami Sun. It has 2 axles with 2 bearings (sealed??) each. Clean riding area. Last replaced 2 months ago. Any suggestions appreciated.... Read more >>
