Harris cyclery logo

Ah, the hand-wringing. It seems to have started with someoneĀ  at the road.cc blog who inquired on our Facebook page, then posted on without waiting for our response.

Harris Cyclery has closed after a 70-year run, hit hard by pandemic supply issues. Sheldonbrown.com got its start when Sheldon worked at Harris Cyclery, and we are very grateful to Harris Cyclery for its support. But, since 2010, sheldonbrown.com (except for the /harris pages) has floated its own boat, through online advertising.

We don’t know yet what other affiliation we may find, or whether we’ll go it alone, but you may rest easy. Ride your bike, and feel free to come to us for help keeping it in top shape.
