My 610 spent 20 years and 27,000 miles as an all weather commuter fix gear until its life ended with a hard crash. Good bike. Very good workmanship (under a very ordinary brown factory paint job - so the workmanship was a well disguised secret). Poor fit for the job until I put an enormous stem on it.

That bike did long hard service with never a complaint. The Trek that replaced it fits me far better and is a much better ride (despite not so nice tubes) but had to go back to a framebuilder for repair for what would have been a warranty issue had I been the first owner.

As for that bike seeing abuse re: being ridden in snow? My bike saw at least as bad, but ... it always wore full fenders.

Edit: it came with OEM Shimano cantis that were so good I quickly took them off and put them on my Mooney where they reside to this day.
