i haven't ridden any contis for over a decade and dropped them due to durability/propensity for flats. succumbed to the hype and bought a pair for a
late 80's steel build (so not the lightest of bikes). only about 400 miles ridden on the new steed/conti gp 5k's but really happy with them so far.
current handlebars that came with the frame are vintage, look great and fit the build but they are slightly too small for me. results in the bike
being a little too "squirrelly" for me but my intuition tells me it's nearly all due to the handlebars. have gone up a few decent climbs and felt
awesome climbing while seated (and generally while standing). hope to swap out the bars in the next month but if i had to buy another set
of tires for one of the other 3 bikes tomorrow, it would be between the michelin pro 4 endurance's or the conti gp 5k's. and i'd likely go with
the gp 5k's.

that said...i occasionally like to think my road bike can double as a light dirt/gravel bike. haven't run the gp 5k's over any d or g and would possibly think
twice about doing so unless i absolutely had to. i know i can count on the michelin pro 4 endurance tires for the occasional shortish foray/expedition/fubar
segment.
