Demonstrates a single spoke removal and installation.

IMPORTANT: Nuts and bolts on your bike should always be tightened to the manufacturer's specifications.

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.

Spoke Removal

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.

Spoke Installation

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.

03/14 Rear wheel keeps shifting

I just tuned my '76 Schwinn cruiser up for spring, and after riding as far as my daughter's bus stop my rear wheel has shifted over far enough that the tire is hard against the frame. So I readjust, tighten it back down, and in the same time my wheel has shifted again. It's gone as tight as it can. I'm wondering if the mounting brackets of the fender are causing the nut to slip. Perhaps moving them to the inside of the frame would help? Any suggestions?

Edit: It only seems to be the drive side that slips. The chain is loose and the tire presses against the non-drive side under the... Read more >>

03/12 HB M960 hub overhaul

So I have this lovely ti tourer with shimano xtr hbm960 hubs, and I am hoping to service these hubs. I see a metal cap on both ends of the hubs both front and back and the metal cap has a space that looks like I can put a flat head screw driver into to pry it off, it has no flats like the other cones I've dealt with. Can't find how to on the internet. Has anyone dealt with these hubs?

02/20 Wheels

I have a 1987 Cannondale racing road bike that I have been using to ride on crushed stone and paved trails. The wheels have worn out and need replacing. I was wondering if I could get a slightly wider wheel that could support a wider tire. The crushed stone makes control a bit hard at times. I am looking for more stability from the bike.
I like the feel of the bike and am very comfortable with the road set up. I would rather not have to buy a new bike.

02/10 What tool is needed to remove this freewheel?

Hello,

I was wondering if someone could recommend to me which removal tool is needed to remove this freewheel? I recently broke a couple spokes and the freewheel needs to be removed to access the hole to put a new spoke in. I put the ruler there to measure the diameter of the space, it's about 35mm-ish. I was looking at park tools freewheel recommendation site, but don't see one that would necessarily match. Would the FR-6 or FR-8 work? Thanks!

12/03 Replacing rear wheel after patching a flat

Hi, I'm having some trouble reattaching my daughter's rear wheel to the frame after fixing her flat. It's a 20" wheel, single speed, with linear pull brakes. I have it reinstalled and with what seems to be a good tension on the chain, but it's rubbing the brakes and it's a real chore to pedal.

I had to go through this just last week when my son did the same with his. It was a learning curve (lots of youtube help) but I got it right on the third try. But he has horizontal forks where the axle goes on, so it seemed to be just a matter of getting it the right distance and holding it ... Read more >>

10/10 Tyres keep popping off wheels...

Hello guys

Just bought a new pair of 700c hybrid wheelset with an inside rim width of 19mm. I have tried to fit schwalbe 700 x 40c tyres on them but the tyres just pop out from the rim when inflated. It seems to be a loose fit. Somebody please advise.

09/21 Mavic Crossroc wheel

Hello,

I bought a wheel set of Mavic Crossroc. The rear hub came with a 12 X 135 set up, but I need to a 12 X 142 mm so I got some adaptors and I have disassembled the hub but I can't figure out how to remove the actual end cap on the axle. Do I have to remove them, if yes how ? If no do the 142 mm just slides over these caps ??

Thanks... Read more >>

09/05 Rear Axle - tough pedaling

I removed my rear wheels on my single drive ancient Miami Sun trike, right rear bolts to bearing, left wheel has a nut on end of shaft ... I had the wheels trued, and tubes and tires replaced ... tires are .25 wider than original. Now when I try to ride it is quite a bit harder to pedal. Is there a proper tightness for the rear wheel axle nut ? or is the wider tire the culprit ? I just assume I did something slightly wrong ... Thanks... Read more >>

09/01 Replace or repair wheel?

Hello All,

I need some advice on whether to repair or replace my rear wheel. I have a decent single speed road bike that a friend built together for me. I let another friend borrow it, and he decided it was a good idea to ride 6 miles on a flat (lessen learned not to let people borrow your stuff). So in doing so, he busted a spoke, and bent the rim. I removed the busted spoke and got a new tube. Its rideable but the wheel wobbles a bit, not terrible but enough to be annoying. Im not an experienced mechanic so I was wondering if this is something that is worth taking to a bike shop... Read more >>

08/11 Remove Hub End Caps

How can I remove the hub end caps from my front wheel? The wheel is a 2014 TBC Revolution Trail 27.5 with 32 spokes. I tried pulling them off by hand and with a pair of pliers but was unsuccessful.

The reason I'm doing this is because I noticed movement when I grip the wheel and move it side to side. I suspect the hub bearings and would like to remove the caps to have closer look and possible replace the bearings.

Here are some pictures of the wheel and hub:

07/30 What freehub do I have?

Hello to everyone,
I'm new to the forum and I want to congratulate with all of you for your excellent work! Now we can go to the serious stuff:

I'm not an expert of bikes and I'm trying to fix my old TREK. The freehub is broken so I decided to replace it. It was not easy but, finally, I removed it from the bike. Now I have two questions:

1) I'm not sure I removed it correctly because the back of the freehub is different from what I can see online
2) if I removed it correctly, can someone tell me what kind of freehub is this? I want to buy the replacement <... Read more >>

07/27 Replace Cassette with Freewheel

I have a road bike with a Shimano Tiagra, 12-25T cassette.  I have a freewheel that should provide higher power on top gears.  How would I go about removing the cassette and hub and installing the freewheel?
What exactly is needed?  Is it possible

07/23 Started my 10 speed to 3 speed hub conversion from 27" to 26" wheels.

The rear wheels seems to fit fine. The spacing was perfect. Both wheels are off of  different Raleighs. The  rear brakes need changing. The bent 27" forks are being replaced with 26" forks. I serviced the bottom bracket and put a single chain drive and new peddles on as well. I think it will work but until it's finished, you never know for sure. There will be 4 or 5 pics. Will change the drop bars to flat bars, put a comfort seat on and see where it goes from there. If anyone has any advice I am interested in hearing it.
