Here's an excerpt from the UCI 'REGULATIONS: CHANGES PROPOSALS PART 1 – GENERAL ORGANISATION OF CYCLING AS A SPORT' (Rules amendments in force 01.01.14),


from here: http://www.uci.ch/templates/BUILTIN-...Y2NjU&LangId=1

which, in summary, says you can have your saddle tip up to the bb centre-line, so long as you are in drop bars, but if you add pursuit bars, the 5cm behind rule applies:


(The bold and strike-through disappeared when I pasted this hear, so i've just deleted the bits with strike-through; i hope i have rebolded all the correct bold bits)

(in bold, the modified parts to be approved)



1.3.013 The peak of the saddle shall be a minimum of 5 cm to the rear of a vertical plane passing
through the bottom bracket spindle. This restriction shall not be applied to the bicycle
ridden by a rider in a sprint event on track (flying 200 m, flying lap, sprint, team sprint,
keirin, 500 metres and 1 kilometre); however, in no circumstances shall the peak of the
saddle extend in front of a vertical line passing through the bottom bracket spindle.

The peak of the saddle can be move forward until the vertical line passing through the
bottom bracket spindle where that is necessary for morphological reasons. By
morphological reasons should be understood everything to do with the size and limb
length of the rider.

Any rider who, for these reasons, considers that he needs to use a bicycle of lesser
dimensions than those given shall inform the commissaires' panel to that effect at the
time of the bike check (see diagram «Measurements (2)»).

Only one exemption for morphological reasons may be requested; either the peak
of the saddle can be moved forward or the handlebar extensions can be moved
forward, in accordance with Article 1.3.023.



(text modified on 1.10.10 ; 1.02.12, 1.10.12)

In force: 1.01.14




1.3.023 For road time trials and individual and team pursuit on the track, a fixed extension may be
added to the steering system; in this instance, the height difference between the elbow
support points and the highest and lowest points of the handlebar extension
(including gear levers) must be less than 10 cm . It is also possible to add a handlebar extension
for the 500 m and kilometre time trials on the track, but in this case, the position of the tip
of the saddle must be at least 5 cm behind the vertical plane passing through the bottom
bracket axle.

The distance between the vertical line passing through the bottom bracket axle and the
extremity of the handlebar may not exceed 75 cm, with the other limits set in article
1.3.022 (B,C,D) remaining unchanged. Elbow or forearm rests are permitted (see
diagram «Structure (1B)»).
