I'm back on track. My ankle is still not right, but it's not stopping me from riding my bike. I've been testing it out on some hills on shorter rides and today it got a full fat 100k including some hills. And a dead owl
For various reasons my bike is in snazzy racy form with no mudguards and rack. First time I've ever ridden it like that. It's probably several kg lighter, as it is also missing all the miscellaneous crap that lives in my rack bag. Unfortunately it didn't feel any different and did not, as hoped, fly up the hills.
