Seatpost wisdom

Always choose the longer postpost

… particularly if you’re getting a new bike frame.

But why would you need a new one?

Because bike manufacturers have gone overboard with sizes and today when you buy a new frame it’s very likely it would have its own seatpost diameter. A quick wikipedia check shows how many “standard” diameters are in existence today. Hold your breath:

22.0, 22.2, 23.4, 23.8, 24.0, 25.0, 25.4, 25.8, 26.0, 26.2, 26.4, 26.6, 26.8, 27.0, 27.2, 27.4, 27.8, 28.0, 28.6, 29.4, 29.6, 29.8, 30.0, 30.4, 30.8, 30.9, 31.4, 31.6, 31.8, 32

Something like 30 if you bother to count them.
