Much has been written about the new T47 threaded bottom bracket ‘standard’ in recent weeks and a lot of people are rightfully excited about it. In one fell swoop, T47 – at least in theory – provides the ease of service and quiet creak-free running of traditional English threaded shells but with the oversized dimensions and enormous drivetrain compatibility that frame designers desire.

So T47 sounds like the solution we’ve all been waiting for, doesn’t it? Yay! Crack open the champagne! Start singing Kum Ba Yah!

Sorry to be the killjoy, but I wouldn’t go celebrating just yet.

Technical pros and cons aside, I’m highly skeptical that T47 will expand into the mainstream where the most people stand to benefit. Here’s why.
