It is supposed to be just a social ride out. When pressed further, the figure of “ohh i’d say an average of 15mph” was mentioned, which I think is a pedestrian pace.
However I don’t want to hold them up unnecessarily, so with that in mind, I was already eyeing up some slicks (28c Conti Grand Prix 4 Season’s on my 24mm ex/19mm int rims?) flipping the stem, and on with some ergon’s w/bar-ends.
Just have to deal with the faux-pax of turning up with a camelbak, baggies, and a helmet with a peak. :)
