Futuretrack 5 by Robert Westall

"Henry Kitson lives in the twenty-first century, where success is determined by being good--not too good--and by a willingness to conform. Those who don't make it are consigned through the Wire, lobotomized or, in Kitson's case, allocated to Tech--a small body of people who maintain the computers. It's not much of a life, but safer than outside, where survival depends on skill, daring and fear of the system. Meeting bike champion Keri is a turning-point for Kitson, and the two form an uneasy alliance to find out just what makes the system tick"--Page 4 of cover.
