    Stainless steel spokes busted with corrosion!

    Why would this happen to stainless steel spokes?

    Maybe 1 or 2 times on sandy beach riding.

    Where there is crust, the spokes break easily.

    Check them with a magnet, good chance they arenít stainless. If they are, probably a cheap grade like you see on outdoor grills that rust.

    Checked with magnet. They seem like SS.

    Front and rear rims are like this.

    On my Specialized with ALex Rims.

    Unless something splashed on them........

    StainLESS not stain free. Extreme pH, chemicals, rubbing with plain steel wool, will cause ss to corrode. I've seen them snap because someone parked their bike in the garage near pool chemicals.

    I found it hard to believe this could happen after only maybe 6 month of use.

    But, okay.

    Thanks

    I've seen it from people who park the bike in the garage near where the exhaust pipe of their car aims. In and out of the garage on a daily basis for years...it'll trash a wheelset.

    So...near an ocean? How close does she live to said ocean? Salt spray is no joke. It's a fine aerosol mist that carries quite a distance....not talking about waves crashing ON the bike.

    Ok... Few things here...
    I believe I see eight gears and QR axles. Also, the spokes are not butted so not high end. I'm sure they're not a high grade of stainless. How old is this bike? ANY spoke will give up the ghost if it gets to be ten years old and it's on a machine built wheel.
    How did your sister possibly ride this bike on beach sand? Those are awfully skinny tires for such activity.

    I ride fat bikes on the beach every winter. I build all of my wheels with black DT Swiss or Sapim spokes. . My oldest fat wheelset I believe is seven years old and no issues yet. Maybe the black oxide coating protects better than raw stainless?

    They are probably galvanized spokes. A magnet will attract very weakly to a stainless spoke.

    All great points... I have a couple of hand built wheel sets that are >10 years old and still going strong. DT Swiss and Sapim are my go-to spokes as well.

    I have a few wheel sets with aluminum nipples but build all of mine own wheels with brass.

    A few years ago, the cafeteria at work was having some sort of a contest and the prize was this crappy coaster brake cruiser. It was in one of the store rooms and a can of soda exploded near it and the soda ate through a few of the spokes. The woman in charge knew I was a bike guy and asked me about it. I ended up re lacing the wheels with decent spokes and did the whole make the crappy bike good build.
    I always wondered what those spokes were and changingleaf probably just answered it. They probably were galvanized.

    My friend, the house electrician won the bike and didn't take it. They ended up giving it to one of the kitchen workers.

    Spokes have an "N" stamped on head.

    No way. The rim and hub flange will break long before a spoke snaps in half like that from high tension.

    See my post on are their counter fit DT spokes. I have had DT spokes break like this and also a generic spoke with no marking on the head also break like that. I believe they are made by the same maker. Also both spokes had the same magnetic properties. https://flic.kr/p/2efovSw
