spokes

[Kano]

Unusual for them to fail on the left as opposed to the right? You mean he's breaking spokes on the wrong side? The one episode was a definite clip out situation -- and he knows it! Replaced the wheel that time, but I think that's the wheel with HIS tires -- he's using my comfort-beast's wheels now, cuz he likes my tires better!

Yes, it's a fairly low end bike, but if he's having a problem that's particularly unusual, I'll point out to him that the bike gurus have told me it could well be something he's doing. He may not listen to us, but it will get him into the bike shop to be told by guy bike gurus!

Maybe we'll try the washer thing -- it could help for a while, especially if he doesn't want to put a lot into this bike. I'd like to see him get something nicer someday, but it's not cool that he's spending time fixing all the time. He's just not into mechanical fiddling!

Yup, he's breaking spokes on the wrong side. The right side gets the torque from the drivetrain, so right spokes are far more likely to break. Tell your DH he must learn to break spokes correctly!

[Kano]

So, he put the wheel back together, turns out this one WAS on the drivetrain side, and decided that the reason it broke must have been cuz he left the dork disk off.

Dork disk is back on his wheel.

Somehow, I don't think that will solve things.

He also managed to have his first flat in the process of changing the spoke -- poked the tube with the nut-widget. Looked like it's harder to get the armadillo tires off and back on than my soft, thin "poppy" tires!

The dork disk prevents the chain from damaging spokes if the derailleur is maladjusted and the chain drops between the cassette and spokes. If he dropped the chain into the spokes, that is probably the reason for the spoke breakage. In that case, be sure and inspect all the spokes near the hub flange on the right side for signs of gouging. If you see any spokes with visible damage, they will break sooner or later so might as well replace them before the do. And check the L limit screw on the RD. Always safer to remove the tire and tube and inspect the rim strip when when changing a spoke.

Cuz he's still at it!

I read through it again, to see what was in here from last year (fun hunting for old stuff! remarkably easy too, as long as I remember to use the advanced search!) and anyway, he doesn't break spokes by dropping the chain into them -- he's good at not dropping the chain (now if he would just adjust the front derailleur so his bike isn't always makin nasty chain rubbing sounds!)

After he managed to flat his back tire on friday coming home from work, so he had to fix it before he could go for an early morning ride Saturday, (armadillos -- they're challenging to flat!) he broke another spoke while we were out on a group ride Saturday -- so had to fix it before Sunday's early morning ride. Now he's starting to get into this bike fixing thing, but this just isn't cool. Since we had the bikes on the car, and the LBS isn't too terribly off our route coming home Saturday, Let's go see what John has to say, eh, dear? He had to stop, get out of the car and inspect the wheel to believe that the spoke had broken -- why would I tell him it was if it wasn't, right? Anyway, he agreed to stop, and we brought a new wheel home.

It's "double walled" and has some different kind of spoke than the one that came standard on the bike did. Will a double-walled wheel help? It's not a fancy wheel, mind you, like some of our guys are riding, but it's not a fancy bike, either!

And would it make a difference if he would gear down a bit more on hills? That torque thing that was mentioned -- would it be better if he'd quit hammering up hills?

How many spokes in the old and new wheels? The number of spokes will make a difference, and the rider's style will make a difference. Definitely harder on spokes to hammer up hills in a high gear. Also easier on spokes if the rider gets off the saddle for bumps and potholes.

Double walled vs single walled rim shouldn't make a difference unless he was breaking spokes next to the rim, but that would be unusual. The old wheel could have been poorly made, with hub flange holes too big for the spokes. Or the rim could have been a little bent, causing unequal spoke tension.

Good luck with the new wheel.

My boyfriend had the same problem for a long time, and he is not a big guy at all (138lbs). He was breaking them on both sides though. At some point he was pretty annoyed and so he placed HED H3 wheels on all his bikes, and a zipp disc rear wheel on his tt bike. I'm quite sure there must be some other easier way to solve the problem, but the aero wheels worked for him.
