Oddss and evens any explanation?

So got to thinking, all my bikes are 55s.

So was there a traditional logic as to which manufacturers went 53,55,57 and those that do 54,56,58?

Facts, speculation, conspiracies…

Illuminati

Everyone should downsize and run a 140 mm stem

I’m not a pro, only a 130

Metric vs Imperial.

Thinking too much.

It’s a conspiracy too vast to contemplate… why do the measure bikes in cm in the US and imperial for everything else?

and why are mountain bikes in imperial and road bikes in metric?

MTBing was invented in the US?

What are these mountain bikes you talk of?
