There were four road models offered in the 1989 catalogue, all of them with a more competitive build. These were the Pro, the Comp, the Prestige and the Pre. Here are two of them from 1989.

Then Raleigh obviously brought them back, since the bike I showed earliier has a 1990 Exage 300EX component group and '90s graphics.

And then there's the Olympian:

My guess is they stopped doing sports touring for 1989 to re-tool the line for 700c wheels, then came back in 1990.
So the sport touring Raleigh Techniums did not end in 1988 or were replaced by race bikes.
