There is one major cause of this problem and it is putting a 1.8mm aka 15ga spoke in a 2.0mm/14ga nipple. This mismatch will screw together and hold under some tension, but then slip. It is easy to test. Obtain a known 15ga nipple. If it can screw on to your spokes at all, it confirms the problem. The same thing could happen with a 2mm spoke in a 2.3mm ...

Pad the freehub body with rags, hold it with a big pipe wrench or vice grips. Another possibility is holding the freehub body pointing downwards in a vice with plastic soft-jaws (or padded with rags, again). If you position the freehub at the side of the jaws you can probably get the lockring tool in underneath.

I would say that your wheels were not initially tensioned properly. The load-unload cycle of riding will work to back off the tension on spokes that aren't tight enough. That you have disk brakes isn't the root cause, though the forces of disks braking act through the spokes whereas rim brakes are already acting directly on the rims. So braking with disk ...

Single wall rims on disc brake wheels aren't especially any more problematic than with a rim brake. It's a pretty cynical way for bike manufacturers to allocate parts dollars, so thankfully it's not super common. Putting a single wall rim on a cargo bike is a bad idea though. Single wall rims are far less structurally efficient than double wall, typically ...

I used a domestic hairdryer for 2/3 minutes , applied the extension and it finally gave. Would also advise against using a blowtorch as may damage components.

Use a strap wrench on the freehub body.

50km/h = 13.9m/s = 833m/min. Wheel circumference is roughly 2m so that the wheel is spinning at 417rpm. Sealed industrial bearings easily withstand 10.000rpm and more. The steel ball bearings inside even more.

Since the question was asked, high-performance carbon wheels for drop bar bikes are evolving towards an internal width of 22-25mm - that is, wheels aimed at both performance road and gravel bikes. I am not sure how alloy wheels for drop bar bikes are evolving, but I suspect they will follow (White Industries already makes an alloy rim with a 25mm internal ...

Per the FAQ, we don't recommend specific products as they tend to become obsolete quite fast. We also don't really discuss product valuation. It's likely that the folks on Bikeforums, where you cross-posted, may offer some discussion on those aspects. However, general upgrade considerations can be a productive avenue for discussion here. You have, with all ...

A rim which is not straight when at rest, will result in uneven spoke tension after it's trued. This is always the case, because no rim is perfectly straight. If the rim is only slightly bent (the 10mm figure sounds reasonable), then the resulting un-evenness in the spoke tension will be moderate and tolerable. But if the rim is excessively bent, or if it's ...

Jobst Brandt's The Bicycle Wheel tells about repairing this failure mode in the following way: In a soft failure the rim has a smooth and continuous bend, and some of the spokes have become loose. If the wheel is deformed laterally more than ten millimeters, all nipples, even on spokes that have no tension, should be unscrewed two turns before attempting to ...

'VP-20' is likely just a manufacturer model number or similar. On mountain bikes wheel and tire diameters are often referred to in inch sizes: 26", 27.5" and 29". Those measurements are nominally the diameter of the inflated tire. What they really mean is the tires fit wheel rim bead-seat diameters of 559mm, 584mm and 622mm. The ERTRO ...
