The UCI, cycling's governing body, has posted income of SFr33.4 million ($36.7 million) for 2013, a 24-per-cent fall on the previous year, when the coffers were boosted by the London Olympic Games.
The federation received an additional SFr1.9 million last year from the 2012 Olympics.
The 2013 World Championships in Florence, Italy in September, was the biggest contributor to the pot, accounting for SFr11.4 million of the UCI's income.
The track and mountain bike world championships in Minsk, Belarus and Pietermaritzburg, South Africa respectively, were the next two most lucrative events, contributing SFr1.9 million and SFr1.6 million.
One welcome decline was that in anti-doping fines, from SFr1 million to SFr300,000.
Meanwhile, British Cycling, in partnership with Manchester City Council and UK Sport, the elite funding body, announced today that the UCI BMX Supercross World Cup will return to the city in April 2015.
The two-day competition will take place at the National Cycling Centre in Manchester, where it has been held for the last two years.
The Manchester event will open the five-stop global series in 2015, with other rounds slated for Papendal (Netherlands), Engelholm (Sweden), Santiago del Estero (Argentina) and Rock Hill, South Carolina (USA).
Jonny Clay, British Cycling’s cycle sport and membership director, said: "We are delighted that Manchester has been awarded a round of the UCI BMX Supercross World Cup for the third year in succession.
"As well as providing the valuable opportunity for our British athletes to compete for qualification points for the Rio 2016 Olympic Games on home soil, the event presents an exciting weekend of entertainment for BMX fans of all ages."
Simon Morton, UK Sport’s director of major events and international relations, added: "UK Sport is delighted that the 2015 BMX Supercross World Cup in Manchester has become the 40th event we’ve supported since London 2012 through our Gold Event Series."
The £27-million ($45.6-million) National Lottery-funded Gold Event Series aims to bring 70 major championships to the UK to build a strong sporting legacy from the 2012 London Olympic Games. Sportcal
