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.
Can anyone tell me if it is possible to fit a hybrid rear wheel on a racing bike frame seeing that both hybrid and racing bike wheels have the same bead seat diameter?

What size 29er tyre can I run on a 700c wheel with an inside rim width of 19mm? Would a 29" x 2.3 tyre be too wide or would it just about work ok?

Have a set of MTB wheels that the rims(aluminum) have some corrosion around where the spokes fasten(nipples). It has a chalky white residue that seems to creep under the existing paint and makes the paint peel off.
What is the best way to clean them up and get them ready for a couple coats of paint?
Thanks !!! ... Read more >>
I put my Park wheel truing adapter onto my Park repair stand and have now had some experience with it. It is pretty neat, very happy with it, and it works well for truing Mountain bike wheels etc. (Not a jig for wheel building of course as other items come into play that this stand cannot cope with) One wheel was so bad I had to loosen all the spokes and snug them all up evenly to get the wheel into a shape I could start from. Another bike the tire was out of round while the wheel was bang on. The more I use it the better I get. So every bike I work on now I can easily check the wheels in mi... Read more >>

I don't believe I've posted this before....
By dating parts, I know the approximate age of Peugeot...
Front Normandy Hub made in 50th week of 1979, and rear Hub made in first week of 1980.
Trying same on Gitane Mixte that we believe is 1970-ish, with same Normandy Hubs and I hit a brick wall...
Stamped Normady, but that's it...
Searching on Internet for Normandy hubs I see only date code info as what I find on Peugeot.
Anybody hear of any other Date Codes on Normady hubs?
Every now and then I try (again) to date code th... Read more >>
have just watched the video on replacing rims. Just wondering what the indicators would be that you needed new rims. The video gave no info on this. Just curious.

I'll preface this by saying I know very little about bike maintenance.
I recently bought a new bike, Vilano's generic, entry level 21 speed. I'd hoped to find a good deal on a used bike on Craigslist, but quickly realized I didn't have the bike knowledge to do that. The Vilano had good reviews for my price range, but I realize that, to an extent, you get what you pay for, too.
I got the bike yesterday and started to do some prep maintenance. I know I could've had a bike shop do everything for a reasonable price, but I like figuring stuff out and doing my own maintenan... Read more >>
Is the rear wheel on a bike properly dished if the rim is equally distant from the frame? I trued my rear wheel a little today, and I'm wondering if I need to go any further to check if it's centered than measuring the distance between the rim and the frame on either side of the wheel....

Hi. Riding in sub zero temps here and my rear brake has seized for the last three days heading to work but today I started off pedalling but after about 100m my pedals no longer moved the rear wheel. I had a major service a few months back where all cranks, chains etc were replaced. Could it just be the cold that is preventing me moving and if so what can I do to cure it.
Sitting sadly on the bus commute as I type.... Read more >>

I need to replace the suspension plate on a chariot trailer. The plates slide onto the axle, and therefore I need to remove at least one brake drum from the axle.
This is what it looks like.
However I subsequently found this parts diagram, which suggests what I've labelled as "final part of axle" and "collar" are actually a single part which fits inside the axle (ringed in red)
I can think of several ways of getting this out - unscrew it (seems unlikely), heat the axle with a blow torch, or hit it out... Read more >>
Question: Say you have a bike that was built in every 10 year increment since 1920 or so...
1920, 1930, 1940, 1950, etc...
What grade of Bearing 100, 50 25, etc would have been used for Mfg, and I realize this might be MFG specific too... ??
What I'm trying to determine (And this could be another of those 'unknown' things about 1970--1980 French bikes...)
If you rebuild an old bike, based upon year, what grade of bearing do you think you're replacing?
I would assume there would be a diminishing returns issue....
