Boom length reduction done I set out on a first real test ride on the M5 today. Nothing fell off or broke, which was good, and I managed not to fall off either.
Bent legs definitely need some work though having not been used since March. Heart rate OK, but legs feeling the difference. Will take a bit of getting used to again before full cruising speed is achieved and full confidence restored. It's not exactly twitchy, but is a lot more laid back than the previous steed.
Need to get a different mount for the Garmin as it's right in my vision and quite distracting.
