The Roni was a revamp of the Cygnus, the Cygnus (q.v.) appeared in July/August 1984, it was designed by two men from March, Nick Wasyliw and Rob Gustavsson and built by Paul Vincent in north London. Apparently it had been conceived long before its appearance but that hardy perennial, lack of money, saw its gestation delayed. Ian Flux did a couple of races in it without setting the world alight. For 1985 the Cygnus was converted to comply with the new flat-bottomed F3 regs and renamed the Roni.
