Troul 

Not sure if I'm paying more mind to the environment conditions or if it's just that dirty out, but it seems the grit, grime, geese poo, & natures compost is collecting on the bicycle more so now than in the past few years.
I generally wipe down the equipment after each ride & look over the mechanics of things, but lately I need to do a bit more than that to "upkeep" the stuff. No big changes to the bicycle nor routes & even if using fenders, guards, mud flaps, or saran wrap, the gunk & junk just clings to everything.
Had some small "twigs", leaves, plant buds, & no longer flying insects wedged in the ders's as well as in-between the cogs. I generally ride the road & paved paths with the road bicycle. If I were rolling on the unbeaten paths or thru wooded trails [no happening with the road-b] it would be a nonissue, but that's not the case here. I'd rather expect other types of debris, such as water bottle fragments, hair ties, discarded face masks, spent candy wrappers & the such, but not picking that junk out as of late.
However, if I strictly ride on the road [with vehicles brushing close by] the aftermath is not near as bad. The minute I venture onto a paved path or road areas that are more "country" like, I can expect a frame full of the aforementioned grime.
For those that ride the road, have you noticed an increase of "cleaning" maintenance after each ride?
