bikeperson45 Posted October 21, 2008 Report Share Posted October 21, 2008 did a crappy one foot drop and one of my bloody spokes snapped.how'd i fix this?(or more importantly, how's the LBS gonna fix it?) thanks Quote Link to comment Share on other sites More sharing options...
Greetings Posted October 21, 2008 Report Share Posted October 21, 2008 You fix it by replacing the spoke or just ride without it. Quote Link to comment Share on other sites More sharing options...
bikeperson45 Posted October 21, 2008 Author Report Share Posted October 21, 2008 Would the whole wheel need to be undone to replace the spoke?Is it safe to ride without it? Quote Link to comment Share on other sites More sharing options...
King C Posted October 21, 2008 Report Share Posted October 21, 2008 Yea its safe to ride without it if the wheel build was half decent. Only thing you may notice is that your wheel may be buckled where the snapped spoke is. Quote Link to comment Share on other sites More sharing options...
eskimo Posted October 21, 2008 Report Share Posted October 21, 2008 Your need a fresh wheel build. There really isn't a fix for it. Now that spoke has gone, the stress is taken upon the other spokes, so even if you replace that spoke another spoke next to it will blow. It'll keep happening..New spokes and new build. If you can't afford it, then don't bother trying to faff about with it yourself if you don't know what your doing. If your running a super light rim like a DOB i'd get it rebuilt sooner rather than later. If it's a rear Echo 07 or something you'll be fine. Heavier rims can support themselves a bit better, even though a wheel is mainly down to the spokes. Quote Link to comment Share on other sites More sharing options...
bikeperson45 Posted October 21, 2008 Author Report Share Posted October 21, 2008 It's a Mavic Ceramic. Ahhhhh. Was just about to make a vid and this happens But must be a warning.Thanks Quote Link to comment Share on other sites More sharing options...
Chris Woodhouse Posted October 21, 2008 Report Share Posted October 21, 2008 (edited) i replace spokes here and there on my wheels all the time because sometimes they are too long so i cant true it, it depends how much of the spoke comes through the hole or how close it is just get a spoke of similar length and put it in if you can get the nipple to tighten on it and get tension back then it should be alright.EDIT: if you cant get a nipple on the spoke just loosen some of the others off there would be no need to taotaly rebuild it Edited October 21, 2008 by Chris Woodhouse Quote Link to comment Share on other sites More sharing options...
psycholist Posted October 21, 2008 Report Share Posted October 21, 2008 Make sure the wheel builder stress relieves the wheel after building. If you've owned the wheel for a while (And it's still pretty straight, so that spoke was under a similar load to the others) it's likely there are a lot more spokes waiting to break on that wheel. A rebuild with new spokes and stress relieving will give you a durable wheel. Stress relieving is where you load the spokes after building the wheel to force them to bed in. When the extra load you put on is removed the peak stress in each spoke will actually be lower than before because you've caused some plastic deformation where the spoke contacts the hub, spreading sharp contact loads over a bigger area. I apply the stress relieving load by squeezing parallel pairs of spokes together with my hands until they start to dig in painfully - Even wearing leather work gloves my hands are still sore by the time I've gone around a whole wheel. The fatigue life of a spoke reduces exponentially as peak tensile stress increases, so for example a 50% reduction in stress leads to a 10 fold increase in life before the spoke fails.

Fatigue isn't the only reason why spokes snap.I'd replace the missing spoke, if others start to snap within a next week or two, get a new wheelbuild.

Bionic Balls Posted October 21, 2008 Report Share Posted October 21, 2008 i had 11 missing spokes on a 36h rim for about 6 weeks last year...didn't have any tools :$ Quote Link to comment Share on other sites More sharing options...

bikeperson45 Posted October 21, 2008 Author Report Share Posted October 21, 2008 So looks like getting it rebuilt...thanks for help Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted October 21, 2008 Report Share Posted October 21, 2008 I broke a spoke quite some time ago, just replaced that one.More recently I snapped a spoke, and the wheel buckled as a result, same day another one went.Replaced them both, but ultimately a new build is the best option.

N.Wood Posted October 21, 2008 Report Share Posted October 21, 2008 I just replace snapped spokes, its not hard (thread it through the hub following the pattern of the others) and tighten it up to true the wheel.Never had any problems doing this, using old spokes that don't fit, whatever. If they keep snapping though, you may need to loosen them all and start again, or pay for a rebuild. Quote Link to comment Share on other sites More sharing options...
Revolver Posted October 21, 2008 Report Share Posted October 21, 2008 I usually retrue my wheel when a spoke snaps.I've never managed to put a new spoke in once the wheel's built without bending it, so I don't bother. Quote Link to comment Share on other sites More sharing options...
bikeperson45 Posted October 21, 2008 Author Report Share Posted October 21, 2008 Thanks for help.SO your saying you don't need to take a wheel apart and lace it again?Wouldn't you bend the spoke like Revolver said?Thanks again Quote Link to comment Share on other sites More sharing options...
Revolver Posted October 21, 2008 Report Share Posted October 21, 2008 Your wheel will be somewhat fine with one broken spoke, or even two. It's just weaker. It's not really the best thing to do, but it's certainly the easiest. Quote Link to comment Share on other sites More sharing options...
psycholist Posted October 22, 2008 Report Share Posted October 22, 2008 Unless you kink the spoke while bending it is not going to affect the strength of the wheel. Make sure to bend the spoke in a continuous curve rather than a tight radius when you are fitting it. Quote Link to comment Share on other sites More sharing options...
eskimo Posted October 22, 2008 Report Share Posted October 22, 2008 I apply the stress relieving load by squeezing parallel pairs of spokes together with my hands until they start to dig in painfullyI also slap the wheel while it's spinning in a pair of forks. Standing on it also helps. Thanks for help.SO your saying you don't need to take a wheel apart and lace it again?Wouldn't you bend the spoke like Revolver said?Thanks againLike i said before, replacing that spoke really isn't going to help. But if you need to true the wheel urgent then i guess your going to have to put one in. If your wheel lasts long enough, save up for new spokes, fresh build and new rim. That's my input though.

neotropolis Posted October 22, 2008 Report Share Posted October 22, 2008 Roughly how much does a complete rebuild cost? Quote Link to comment Share on other sites More sharing options...
Jamie_Neal Posted October 22, 2008 Report Share Posted October 22, 2008 Personally, I can only remember snapping one spoke (in my front wheel) and I just replaced it and its been fine for at least 6 months. I'd say just stick a new one in, true the wheel up, release the stresses in it. I'll try and explain how I do this but will probably fail so I'll explain the method I used to use which is sticking the wheel on the bike, riding along and trying to lay the bike as flat as I can. Doing this, you can usually hear the spokes pinging which sholud settle them. Then check the wheel is still true - if so, go ride - if not, retrue and repeat the process.D521 should be very durable and a snapped spoke shouldn't affect the rim too much.Re-spoking/rebuild is probably in the region of £15 and new spokes are probably £12/15.I'd go for sticking in one spoke first, if it/one near fails rapidly again, look at getting the wheel redone.Cheers,Jamie Quote Link to comment Share on other sites More sharing options...

Doing this, you can usually hear the spokes pinging which should settle them.What you describe will not put anything like enough stress on the spokes to stress relieve them. The pinging you hear is wind up in the spokes from friction between the spokes and nipples causing the spoke to twist as you tension the wheel rather than causing the nipple to thread further onto the spoke and the twist releasing as the wheel is rolled. When adjusting spokes it's best to turn the nipple about 1/8 to 1/4 turn further than you intend to adjust it to and backing off the extra to reduce/eliminate twist during building.

Jamie_Neal Posted October 23, 2008 Report Share Posted October 23, 2008 Fair enough. I think I'll stick with the way I do it for now as I can still only remember snapping one spoke (have bent a few wheels in half though but thats due to crashing, no snapped spokes) as I'm too lazy to spend any longer on building wheels.

psycholist Posted October 23, 2008 Report Share Posted October 23, 2008 Stress relieving takes all of 2 minutes after the wheel is built - often it doesn't even affect the trueness of the wheel either. Since I started building and stress relieving my wheels in 2002 I've have one spoke break and it broke at the threads in the spoke nipple rather than at the bend which is guaranteed the highest stress area on the spoke before you stress relieve. Modern components are well enough made that you can get a couple of years out of spokes even when they're not stress relieved though it will be a lot more if you do.
