Bateleur1 Posted August 31, 2020 Posted August 31, 2020 So having crap weather the weekend, it was a good time to service the road bike and true the wheels again. Much to my surprise I found this on my rear wheel. It is the DT Swiss PR1600 rims that came with the Canyon as I bought it and yes we are over the 24month warranty period that according to the DT Swiss website they give to all there products. Well to be fair, these rims already clocked about 14 000 km but I have never had this happen ever on any of my alu rims. Could this just be normal wear and tear or could this be a manufacturing problem and if possible how could I avoid it. I ask these questions as I need to decide with what I replace this rim. The same brand and type or should I look at something else. Other than this these wheels were absolutely a joy to ride. Oh the weight limit on the wheels according to the DT Swiss website is 120 kg and I am clocking in at 90kg so don't think that was cause. And there was no event that I recall where I hit something (like a pothole or similar) that could have caused this.
Jewbacca Posted August 31, 2020 Posted August 31, 2020 How often do you 'true' the wheels? When you do, do you loosen everything to thread height and start again from scratch? Alu wheels do fail like this unfortunately. It's not uncommon. The MTB guys who own/owned Stans rims deal with nipples pulling through often. It could be overtensioned spokes or it could be general fatigue and a small bump at speed. But ja, It's toast Bateleur1, DieselnDust, intern and 1 other 4

Only replaced 1 spoke on the front wheel once and two spokes on the back. The spoke has not been replaced where this crack came though. Jewbacca 1

This will result in massively over tensioned wheels that either taco or pull the nipples through the rim. That sucks, I'm sorry. Failures are rubbish and just throw unwanted spanners Bateleur1 and Dicky DQ 2
Spinnekop Posted August 31, 2020 Posted August 31, 2020 Dan sou die raam onder my dik gat gekraak het Ja maar Cannondale maak net 'n kraak GERAAS........hy kraak nie rerig nie. Heheheheh. Daai rim kan jy maar weg gooi. Of maak 'n mooi muur horlosie.......julle Duitsers is mos slim met die goed.En dan smeek jy mamma om vir jou mooi mooi stelletjie carbons te koop. Enige rede vir nuwe wiele is mos 'n goed genoeg rede. Wannabe and Bateleur1 2

capediver Posted August 31, 2020 Posted August 31, 2020 Anyone know of a good ally welder, or do you think duct tape will do the trick... My mate was stopped at a traffic light..(gasp!) and as he took off, so did his rim! Huge explosion....3.5 Bar with 2.3" tyre.... Duane_Bosch, Wayne pudding Mol, intern and 4 others 7
Schnavel Posted August 31, 2020 Posted August 31, 2020 My mate was stopped at a traffic light..(gasp!) and as he took off, so did his rim! Huge explosion....3.5 Bar with 2.3" tyre.... Therein lies the problem - 3.5bar?!?!
capediver Posted August 31, 2020 Posted August 31, 2020 Therein lies the problem - 3.5bar?!?! I thought so too but the tyre is recommended up to 3.4bar...I'm betting on rim fatigue and if you look at the ally nipples they are corroded as hell...it appears water may have gotten into the rim void and the nipple holes are cracked on the inside...combined with the slight over pressure...Kablaamm...scary!

Bateleur1 Posted August 31, 2020 Author Posted August 31, 2020 Well I just spoke to the DT Swiss agents here in Germany. They said it should not have happened. Even if it is out of warranty I must send the rim in for them for inspection and they might actually replace it. shaper, dirtypot, Myth and 4 others 7
Rudii Posted August 31, 2020 Posted August 31, 2020 A few cable ties and duct tape will fix that little problem Anyone know of a good ally welder, or do you think duct tape will do the trick...

Skylark Posted August 31, 2020 Posted August 31, 2020 Ah ok.. I just know of some guys who meticulously true their wheels but don't release the tension before doing so. This will result in massively over tensioned wheels that either taco or pull the nipples through the rim. That sucks, I'm sorry. Failures are rubbish and just throw unwanted spannersCan you expand on the correct process please?I never knew you had to release tension on all the spokes before truing, none of the wheel truing how to's I've read ever mentioned that. Though I did always wonder how the winding up and tensioning of the spokes would work out over the life of a wheel. Jewbacca 1
