Back Wheel, Knackered?

Featured Replies

Hi guys,

can anyone help me,

i was at a trial 2day and my back wheel bearings blew on me and so did 5 spokes, how much will this cost to restore back to normal

REV`er :madsanta:

Im having problems with my rear wheel also, getting loose spokes and snapped spokes quite often.

You might want to need your wheel re-trueing. This is quite/very difficult to do if you dont know what your doing.

You can send them (as I am doing) to a specialist, not sure as of yet how much it costs, but my guess is anywhere from

unlucky chris remember dont send it to the specialist that briggs sent his to you will never c it again

but i will will not name and shame that dealer :D

but they no whom they are

I think you should name and shame them. Stop other people from misfortune! They know who they are, but everyone else doesn't.

Remember when you are talking about a spoked wheel that what happens to one spoke can and will effect all the other spokes. If one spoke is loose, the loads it normally handles are passed onto the others. If one is over tight, it is taking excessive loads for the others.

Broken spokes are almost always a lack of maintenance or over tightening.

If the rim is in acceptable condition, a good wheel builder can true it better than new. However, there is a point where a wheel can no longer be trued. Flat spots (big ones), severe warps (taco shaped) and such are grounds for a rim replacement.

Moral of the story, check your spokes often and thoroughly and you'll always have round, strong wheels :D

Can the 'roundness' of the wheel be seen if he bike is raised off the floor, and the wheel is then spun quiet fast?

If it's substantially out, definitely. If you want to be more accurate, fix something, like a screwdriver to the swingarm to use as a visual and audible guide (it will rub and make noise if out of true, side to side). If you fix it fairly solid and watch the edge for "up and down" you'll see it clearly.

There is a good explanation with pictures on how to do this on the RYP site, www.rypusa.com, Sherco then manuals I believe.

If you lost bearings and 5 spokes, I would say your maintenance has been a bit lax to say the least.

I have never had much luck replacing single spokes.

If you are going to do that, back them all off and then bring the tension up on them all evenly as possible. When the spokes are carrying unequal amounts of the load is when they usually start snapping.

Ron Milam also did an article about that with the imortal quote from Charlie Roberts, loose spokes don't break.

It is located on the STRA website, www.setrialsriders.org

When you put in your new bearings, pull the seals and fully pack them with grease, this will prevent water intrusion. (put the seals back on when you are done by the way)

Be careful (read do not do it) when you are tempted to apply heat to your spokes because you cannot get them to break loose. Good penetrating oil, weasel p***, or whatever you care to call it, patience, and a bit of luck go a long way, or my technique usually involves bolt cutters and 32 new spokes. (maybe 36 depending on your bike)

Have never been real successful at straightening large bends in the rims, or dents. (not out of true conditions, but actual bends) the aluminum the rims are made from seemed to be work hard with about one bend, and bending them back has always destroyed them for me. (I am not talking about correcting an out of true condition with the spokes, I am speaking of a "bend" such as you dropped off a 4' drop onto a sharp rock with the rear wheel and "Bent" one side of the rim)

Anyway, I have seen some wheels with some pretty tremendous bends and dings in them hold tires and air just fine, so leave well enough alone when it comes to them, and as you are truing, just go to each side of the damaged area.

I have probably thouroughly confused you at the moment, and if I have, just flush any thought of this post right away.

isnt it slander if i publicly name and shame this dealer :D

The company was Lewisport my friend delt with and he had a broken front wheel. They said " you'll get it back in one week" but in his case 1 month.

Gavin :santa1:

There is a new dealer started up in Fort William the guys name is Kevin Dignan and this is where we get most of our parts from.

Why do I feel there's more to this story? :o:D

Sorry forgot to say we broke the guys legs JOKE!!!!. NO THATS ALL THAT HAPPENED SO IT PRETTY BAD SERVICE.

Eh? Why don't the bike manufactures employ all the wheel builders to do their wheels! :D

If you are going to replace all your spokes you should tighten them diametrically (look it up Wonder plop) and not one next to the other. This should ensure an equal load between spokes.

:D Funny you say that, as back in the days when I was involved in the bicycle biz, the first thing you did when building up a new bike was detension all the spokes, then tension and true both wheels properly. Slow and tedious at times, but well worth it. Nearly all bicycle wheels are machine built from the factory as I am sure are motorcycle ones....some good, some not so good ;)

I use a zip tie.

Quick, easy, doesn't bugger up the rim or stop the wheel from spinning
