why should I have to adapt my technique to make up for the bike’s failings?
Well that’s one way to look at the issue.
Thing is though there are also many positives that come from a bike having a low BB and if you’ve intentionally chosen to buy a low BB bike it’d be pretty stupid not to adapt your technique to make the most of those positive traits. It’s actually not difficult and looking ahead, planning your line, timing pedal strokes and paying attention to foot placement will improve your riding everywhere.
2019 Spectral’s don’t have what i’d consider an overly low BB height either. Repeatedly smashing your pedals and toes into stuff isn’t a failing of the bike it’s a failing of the rider.
