Hi Patrick,
I could never tell what which was worse: going down College Street in
Burlington on a fixed gear in the snow & ice or going back up it!
Enjoy!
Chondromalacia is a specific pathology in which the articular surface
of the knee cap softens. This problem typically responds well to
activities which compress the cartilage ("gentle" compression and
release of articular cartilage appears to be the way in which these
tissues acquire nutrients as they have no significant intrinsic blood
source). If you're mashing along, not experiencing lateral/medial
deviation of the knee (knees "diving" toward or away from the top-
tube), and not experiencing pain... well, no good reason to stop.
I've no idea, really what constitutes low cadence... 80 rpm seems fine
under most circumstances for me... 12 rpm seem kinda slow unless it's
really steep...
