Problem - I bought a set of alexg6000 rims, and they are of course, non machined sidewalls yet ridiculously cheap.
I run two brakes on my single speed. After a couple of days, they are making a horrendous screech when hard braking is applied. I understand this is because they are non-machined, I also know the powdercoating on the wheel will wear off over time.
The question is, is there a technique, product or way of reducing this noise? Without resorting to buying new wheels?
Just wait until the powder wears through. I had an issue a while back with a nmsw and it was so loud it was embarrassing. But it stops once the powdercoat wears away.
Okay, might just take it for a ride one evening and roll down some hills while braking slowly. Might also try to smooth out the weld seam on the wheels because you can feel the jolt of it!
I had the same problem on some non-machined wheels and it was solved by swapping for some other pads that I had lying around. But I can’t tell you which ones to buy – maybe something softer? – I literally just swapped the pads from another brake I had in the parts box (from Dia-Compe standard to Tektro standard IIRC) and the problem was solved.
Those clear BmX pads screech horrendously. I now have black pads on the front of my new steed with alex eBay rims too. So far so good very little noise, the occasional squeak so I Learnt how to skid instead lol
