It’s not total bollocks- the trunnion shock thing is totally valid, means you can fit a longer shock in the same space, or fit more gubbinz in the shock. Which is why Trek have been doing it for years, without any need to invent a brand new standard. Hmm.
But though they seemed to talk mostly about trunnions initially, I see that’s largely falling by the wayside and metric shocks come in both forms. Of course, there’s absolutely no benefit to a metric standard shock. How surprising that the version that provides an advantage was trailed and marketed in order to give a positive marketing message, but the version that doesn’t seems to be becoming more accepted.
The weird thing about it is the timing- they should have waited a year or two so that all the magpies replaced their obsolete non-boost wheels, frames and forks, and then made their new bikes obsolete with a new noncompatible shock.
