Re: [RBW] Re: Rim life - shimano vs. other brake pads?
Thread successfully derailed :) FWIW - this thread and article triggered the question for me whether I should continue using the Shimano pads I have on my bike (s) or replace them. https://thorncyclesforum.co.uk/index.php?topic=1236.0 https://novemberbicycles.com/blogs/blog/brake-pad-tech-rim-brakes On Tuesday, March 5, 2024 at 5:26:37 AM UTC+5:30 Bernard Duhon wrote: > > > > > I have two sets of 26 inch rims: > > one has dots periodically drilled into the surface.

RE: [RBW] Re: Rim life - shimano vs. other brake pads?
I have two sets of 26 inch rims: one has dots periodically drilled into the surface. When the surface gets worn down & the dots disappear and you should replace the rim. I have another set which has a groove all the way around the rim in the center of the breaking surface. When that grove disappears it's time to replace the rim. It was a practice common though not universal in mountain bike rims. All rim brake manufacturers should do that. Measuring wear with a set of calipers is imprecise at best. Each rim manufacturer may have different standards as to how thin the breaking surface can get before replacement. If they do there are a lot of “ safety considerations ” baked in. After 12,000 miles of few gravel & fewer hills the “dots” are still visible.> From: rbw-owners-bunch@googlegroups.com On Behalf Of Brian Forsee Sent: Monday, March 4, 2024 9:56 AM To: RBW Owners Bunch Subject: [RBW] Re: Rim life - shimano vs. other brake pads?

[RBW] Re: Rim life - shimano vs. other brake pads?
I look for concavity, though I like rims that have wear indicators built in. Once I can see the concavity, I start to worry about it but I think you can ride a rim for a pretty long time in that state (depending on conditions, obviuously). Riding daily through the winter, I go through rims in 3-4 years.

[RBW] Re: Rim Life
Thanks for the great advice, especially that Iwanson gauge! I've been looking for a device like that and it's not a high cost item, either. Come to think of it, we cyclists owe quite a bit to the dental industry - there's this nice gauge and then they also have an oral irrigator with a curved plastic tapered end. The end can be cut to the desired width and the irrigator filled with grease. When the plunger is inserted one can apply a nice even application of grease around the cup of a hub, making a neat place to insert the balls to hold them in place for reassembly of the cone. Thanks again!

Damn, I'd say you are already getting great rim life! I commute through Portland's winter, and my rims typically last 3-5 years before developing serious groves or cracks.
