So, what exactly is this new solution? The real irony is that the latest "new" bottom bracket standard isn't new at all. Several mountain bike makers are bringing back the traditional threaded bottom bracket.
|New for '17 Specialized Enduro. Threaded bottom brackets, anyone?|
|Don't ask me about SWAT, or ManFu. And if you mention X-Wing, I'm going to think Star Wars. But listed right there in the new Enduro's specs is something we'd been led to believe was obsolete: a threaded BB.|
They aren't the only ones, either. Niner bikes has put a 73mm threaded bottom bracket into its newest Jet 9 RDO, a short-travel trail bike.
It looks like some of the bike makers are considering the traditional threaded BB because of its well-known reliability, even under harsh conditions. Some also cite the ability to use threaded bottom bracket shell inserts that also incorporate threaded bosses for some common chain guides.
Some companies never actually abandoned the threaded bottom bracket - like Santa Cruz. But now, instead of having to explain why they stuck with the "old tech" when everyone else was switching to "new-so-they-must-be-better" press-fit bottom brackets, Santa Cruz can now sit back and say "See, we were right all along."

Are threaded bottom brackets poised for a real comeback? It's too soon to say for sure - but it's an interesting development all the same.
