This is fascinating, I built my wife's Platypus with brass ferrules on all the cables. I'll have to pay attention to them and probably hit the contact points with aluminum with grease soon. We live in Rhode Island so the weather isn't on our side when it comes to slowing corrosion. On Friday, S

I've been looking into this more for fun - because why not? It seems like using a non metallic barrier (aka) grease may be preferable to metallic such as copper or aluminum. Wax may also work well too. At the end of the day most answers were referred to regular maintenance especially in wet cl

Good coverage here. I stopped using brass bits on bikes a few years ago after a single brass ferrule issue, and I always wondered if anyone else had issues as the rise of brass bling took hold in recent years. On Thursday, September 5, 2024 at 10:44:41 AM UTC-4 Jim in Mpls wrote: > I also greas

I also grease the cable heads(which I believe are zinc?) to help prevent seizing in the shifter bodies. Jim in Mpls On Thursday, September 5, 2024 at 8:30:50 AM UTC-5 eric...@gmail.com wrote: > Thanks to everyone for your replies and notes on galvanic corrosion and > otherwise! > > I haven't

Thanks to everyone for your replies and notes on galvanic corrosion and otherwise! I haven't greased any of my brass ferrules. I did liberally grease my brass Blue Lug crank caps, tho. I have considered greasing them or coating them with some Renaissance Wax which certainly couldn't hurt but I

Hey eric, Yeah ive had similar issues. Had a mildly stuck cable end in a silver 2, think i was able to get it out with a needle and small hammer, basically punched it out. Noticed the brass ferrule corrosion too. I’m still working through a stash of them, but ive also been getting over my bra

Thanks for the write-up Eric. I'll give my brass parts a once over a couple times a year after reading this. Did you grease your ferrule exteriors before installing? I typically give any brass part a liberal greasing before installing, which in theory should help prevent, or at least slow galvanic

A friend swore off the brass self extractors (White Industries, Blue Lug, Etc.) for exactly these same reasons. He’s been encouraging me to do the same for over a year now.I really should replace the two sets I have, even here in arid Southern California.P.

h. This got me thinking about my beloved Blue Lug brass crank caps on my riv silver cranks - especially living in the pacific northwest. Curious of ample grease and yearly teardown will prevent the galvanic corrosion. On Wednesday, September 4, 2024 at 1:29:48 PM UTC-7 Patrick Moore wrot
