Bent quick release skewer
I have this bike, rode it even less than a month: https://breezerbikes.eu/products/radar-expert
Recently I went to check the wheels (not the first time since I got the bike, I have already taken them down before). To my unpleasant surprise, the rear qr skewer is bent on the screw side (so the drive side, I tightent it on the other side). I wouldnt even notice it if I didnt try to pull skewer out of the axle. It immediatelly reminded me how much I hate quick release axle. This is not my primary but secondary bike. The axle looks ok. The wheel was not sitting on the skewer, but the axle. It was tightented propely. Yes, the rear triangle has play, its a steel gravel bike, so there is movement when I ride. Now I ordered a new skewer, but its un unpleasant reminder on how quickly the things can go wrong. No, there is no warranty. Currently my biggest fear is if this happens again, in which case I really dont know what one can do. I certanly cannot change skewers every month. Was it the poor quality ( I doubt), or did it got loose (more than it should) during the ride for some reason I cant tell. |
Was it steel, titanium or aluminum or what?
Get a DT Swiss steel one. Actually, get two, one for the back and one for the front. The design is superior to any conventional quick release (including my Dura Ace internal cam). Skip titanium. It stretches (and bends) more easily, and costs much more. The DT Swiss steel skewers are the next best thing to thru-axles. |
Something bent that skewer. Impact? Wheeling the bike past a doorway? (Usually the RD hits first and you notice.) Or perhaps the skewer nut isn't sitting flat. Look at the outside flat of the dropout and inside of the nut. Or the dropout is askew. (Are you bending or breaking axles?) With everything straight and proper, any skewer, even cheap ones, should stay straight for years and decades.

"the rear triangle has play."
:wtf: I don't know what this means, but it sounds like a much bigger issue than a bent skewer. |

If it bends some,, it then wants to Reassume it's previous shape.. a well known factor.. See: "Metal Memory of titanium"... and it is far more resistant to bending than steel.... that is why it can have far thinner wall thicknesses than steel when formed into tubing....in the case of QR skewers, the rod is a solid bar stock. Funny, why isn't the option of CHROME MOLY skewers mentioned... hmmmmm.... |

The DTs may be that super but an ordinary steel internal cam Shimano OEM QR works very well, has the modern superior cam design, steel skewer (yes, stay away from ti and aluminum skewers; they stretch too much) and will last many years of good service. (And not cost very much.) Used ones at a coop, $2?.

Just to be clear, the above is much more common with a freewheel wheel. This bike appears to have a freehub wheel which is very difficult to bend, much less break. |

Was it the poor quality ( I doubt), or did it got loose (more than it should) during the ride for some reason I cant tell. and everyone needs to realize that STEEL IS FLEXIBLE... and STEEL FRAMES DO FLEX.. "Was it steel, titanium or aluminum or what?" ALUMINUM SKEWER RODS? Really??? that is STUPID. wow. As to titanium.. it Stretches to nearly 50% more than it's length before it breaks... Steel wants to break WAY Sooner... and no one has yet mentioned Titanium ALLOYS and their Aerospace capable qualities... All titanium we end users see is Alloyed before distribution...Raw Titanium is nearly impossible to machine/form/use... and Steel is an Alloy too, literally THOUSANDS of steel alloy combinations exist... Cro-mo is a range of STEEL alloys., etc. the OP or someone else whacked the threaded end of the Skewer on something then found the bend later... a very common thing, IMO. if the bend is less than 20 degrees or so,straighten that sucker and go riding.... unless it's an "aluminum" skewer rod, then sue the company for endangering you life . A bit on Titanium alloys... https://material-properties.org/stee...pros-and-cons/ ALUMINUM Skewer Rods? Really? SMH. Examples, please.. i need the laughs. |
Let's focus on the basics. Skewers don't magically bend. So, either it was bent or there's a reason it bent.
Normally there's no load on a skewer other than the tension from the cam, which wouldnt cause bending, so the key is figuring out what isn't normal. So, broken axle, axle not properly supported in the dropout, dropout face not flat, QR accidently tightened with wheel half way into dropout, QR end banged into when mounting or transporting the wheel (my hunch). In any case, arguing about QQ strength or design is pointless. The skewer isn't the problem, something else is |

Unless it's an "ALUMINUM" skewer, eh? ;)
A skewer is supposed to be tensioned between 2 flat and parallel support surfaces. There are no other loads UNLESS something else is wrong. Other than that even one made of salt water taffy wouldn't bend. |

Try $5 and up... although blowout sales of off brand ones can get the price down to $2 each...or a bulk purchase of ten or more, during the winter doldrums...;)

If it fits through the hollow axle and clamps, don't worry about it.

Why would an aluminum skewer bend without some outside cause.

Titanium will stretch about 50% more than steel. (Look up the Young's modulus.) The titanium rod is restricted to be of the same diameter as the steel rod it replaces, so this is a critical shortcoming for something like a bolt or a rod. "chrome moly" is a form of steel. They use stainless steel because it is less prone to rust, but other alloys like Cr/Mb are stronger than stainless.
However, your random Capitalizations and punction's really make your assertion's Much more comPelling. Apparently, certain things REQUIRE emphasis.... which is the PURPOSE of some of my caps, chap. would you prefer "!!!!!!!!"? as to stainless vs. cro/mo... cro/mo resists rusting... it's a Chrome characteristic. that's one reason why it's also ALLOYED into Stainless Steels. |
Welcome to my iggy list. You are wasting everyone's time.

If you just turn the lever, threading it, and not closing the lever to tighten it, the skewer will not be tight enough and is probably the cause. John |
