Awesome ! Thanks for that. What problems were u having with alloy nipples? Mine kept unscrewing, but a drop of lock tight in each one did the trick.
Alloy nipples on all wheels are particularly susceptible to corrosion. If you live near the beach or ride on roads that have been salted, you will likely experience Nipple failure at some point. No one likes (NF) nipple failure.
This can simply mean that they lock up completely. If you try to turn the nipple, you will only twist and stretch out the spoke it attaches to. Occasionally you may be able to free locked nipples with some penetrating lube.
Worse off, the nipples corrode badly and the threads break free under load.
This is where brass nipples are a better choice. Yes, they are heavier and yeas it is rotation weight at the worst spot for it. But consider that they rarely seize, break or fail. They are also happier at higher spoke tension.
I have taken to building wheels with brass nipples on all occasions, unless otherwise instructed by the customer. At minimum, i recommend this on the drive side of the rear wheel as this is the most crucial spot on any wheelset.
Unfortunately they only come in Brass colored or Black. Thankfully the brass color is much nicer to look at than the ugly gold colored alloy nipples.
You might find it interesting that ENVE uses brass nipples on their carbon wheels. They found out the hard way that the alloy nipples were failing like crazy. They are good enough to replace the alloy nipples on their wheels with brass for no charge if you send your wheels to them.
This is reason enough to NEVER EVER buy a reynolds wheel as they recognize the issue but continue to ignore it. I pick on reynolds vs other brands that do the same since I see them locking up more often than others for some reason.
On the Sram ROAM 60 wheels i popped one alloy nipple and just rebuilt the whole wheel with brass.
