badllama:
Specliaized wheels ofte do use alloy nipples & usually do fall to bits when you try & touch them.
They also appear to often be built with spokes that are slightly too short, so the nipple isn’t properly supported & snap-sometimes meaning the only correct & safe way to repair the wheel is to either rebuild completely or replace the wheel.
This is another concern in that people often believe they understand the problem with their bikes, but when it really comes down to the underlying issues & causes they sometimes don’t.
