Bikes no longer in the "stable":
Road Bike 1976 - 1982 stolen

(still grates

)
Road Bike 1982 - 1995 (c1975), given to a good home.
Road Bike 1986 - 1996, frame damaged beyond repair

.
Can't let them go voluntarily (with the one exception across 40 years).
Looking for one more Road Bike (Titanium) in next 5 years, and one final Road Bike (hand made steel frame) when I retire (Mrs TB is really chuffed!

)
