As it turned out, we had over 2" of rainfall last night. No wonder my clothes and shoes were so saturated.
I don't know if there's any handlebar tape known to man that won't get slick with that much relentless rainfall. I probably should have worn gloves - or not?
The MKS Lambda pedals also got a bit slippery but my shoes did not slide off. I did avoid high cadence and coasted in platform (3 o'clock + 9 o'clock pedals) a lot.
