This week on the Pinkbike Weekly Show, Mike Kazimer joins Christina and Henry as they catch you up on the latest First Ride's with a bit of insight. They jump straight into Recreational Wrecks, 2 Min of Tech with Kazimer and his latest First Ride experience, the latest Pinkbike Podcast episode with Aaron Gwin as the guest, and round it off with some Friday Fails Breakdowns.

Let us know what your next dream bike will be... a solid do-everything rig or a superbike that also does it all, but with some assistance on the up's, or something else!
i havent tested them but can tell you DT swiss actually is durable from the few thats ive had.
Alum will fatigue eventually - it's the nature of the material, how long, fast and catostrophic is highly dependent on use case.
hand-built with solid and boring traditoinal parts is always way cheaper and more reliable. j bend forever.
Been on DT Swiss aluminum (511 or 471) and they are bullet proof.
The fatigue behaviour of aluminium and its alloys is a lot worse than steel. The spokes might see more severe load variation but you can't have one without the other.
I had a wheel recently develop cracks from almost half of the spoke holes. It was presumably assembled incorrectly and was replaced under warranty, but that's still fatigue.
thanks for the data
Now I'm wondering whether those riding big wheels damage their rims as often as those riding smaller wheels with a similar rim design. Of course if the "performance" those big wheels bring allows one to "tap into their full potential" as a rider then that's all good of course. I'd rather stick with what keeps me going for cheap. Replacing a rim every year sounds like no joke. Especially if you can no longer get hold of the exact same type and you end up replacing the spokes as well.
In a straight wheel you won't find the tension to be off, unless the tension was off since the wheel was built (or trued).
Much more noticeable, once you bend a rim sideways ( taco) tension has to beade very uneven to straighten it, leaving spokes on one side noticeably tighter than the other. Next time you land sideways on the side with no support from loose spokes it all goes bad. That's why when you bend a rim, it's better to not straighten the wheel, but just re-tension evenly, giving more even strength and less spoke fatigue ( loose spokes bend a little all the time and work harden until the break)
And yes if spoke tension is off when the wheel was built (or trued), then it will be off while the wheel is straight.
But you don't need to check the tension regularly, to find out the wheel was badly built.
You will see that the first time you check the tension.
The main point is that you need to true and check your spoke tension fairly frequently to maintain wheel strength. So many people riding expensive carbon wheels with noodles for spoke tension, completely negating the performance the rim can bring. That is until the wheel starts creaking or snapping spokes. If you buy fancy rims, spend the money on a spoke nipple wrench and park tensiometer.
Either way, compared to so many other elements of a bike, the tools needed to build and/or true a wheel hasn't changed much. It is a worthy investment that pays for itself.
vast majority are riding in local trails on trailbikes or hardtails.
That said I think I want my wheels/tires to fail prior to my body strength/ impact ability??? Honestly not sure.
Reasonable tire pressure, monitoring wheel tension (tension > wheel true, according to DT Swiss), and keeping mileage in mind is important. Aluminum will fatigue no matter what. Heavier and harder riding will greatly reduce life.
However, that same rider on the same course might not dent a rim over the whole weekend if they're chilling way off the race pace.
My Enduro rider's wheel that I built in the spring last year has lasted the whole CDC season (Multiple podiums) and is still going strong. We use exclusively Ex 511's. It is entirely dependent on how you behave on the bike.
Wheels last as long as they do, better quality rims and hubs last longer, but other than that, there’s no technology that’ll make a wheel longer lasting.
Might as well complain about tires not lasting long enough …
Now with carbon wheels I might rebuild with new spokes after quite a few seasons. But I don’t ride as much anymore and ride like the old man that I am.
Roughly 3500 miles on some carbon rims from a company that no longer exists, roughly 150 miles of which were in whistler
3600 miles on my 24 hole gravel carbon (Synergy branded) front wheel, fatigue and delamination, rear with 28 holes is okay but damaged from potholes
Over 10 ft to flat on my Nextie carbon front bmx rim, still going string despite some bent spokes from that and a bent steerer tube
Carbonfan mtb rims cracked at the nipples, 3000 miles, currently used to install rimpact inserts
Stans flow 26 inch 28 hole, about 1500 miles on my xc bike, currently being used as the spare on my dirtjumper, not dead yet
Stans flow 29 that replaced my arch under warranty i think made it 3500 miles
So I am not really getting any extra life out of carbon except on the bmx bike for which i have ovalized multiple aluminum rims in short order.
I should probably start building my own wheels with washers...
meh
Either you have zero skill / the worst line choice in the world, or this is actually Goldstone’s burner account…
try riding SS rigid for awhile, then you won't have issues with stuff breaking.
