Eclipse were an English shop brand making mostly touring and a few clubman type bikes.

Frame building was mostly outsourced to Orbit and many if the frames even have the Orbit embossed seatstay caps still present.

I’ve seen a few come through shops and the co-op here (in the UK) but they’re not what you’d call common.

Quality is usual Orbit, either very good or a ‘Friday afternooner’ with a bit of sloppy work, normally good though and ride well enough but Eclipse were always very workmanlike on the finish, plain paint nothing fancy etc.
