Info about the Competition from these years (late 60s) seems limited. The '69 catalog listing (on the same page with the Professional) states in bold, "Write for Full Specification".

It appears that the original owner did a re-build sometime in the mid-80s - wheels, drivetrain, etc. From Disraeli Gears, the RD identified as Shimano Deore XT (M700) intro'd in 1983 which matches the age of the rims. Maybe that's when the replacement fork was needed.

Not my bike but the wrap-around seatstays and headbadge made it worth posting.

Still wondering about original build if anyone knows?
