I have read with interest Dan Empfields articles about tri specific bike fit. I am not sure if I have understood some of the more technical aspects but I have the following conclusions and questions to pose: My Conclusions - - the angle between torso/legs i.e. hip angle is very similar in the forward position to a roadie on the hoods - the entire cylist in the forward position is rotated forward dropping the head and shoulders and pushing the feet back - this affects the handling of the bike (too much weight forward) so a steeper seat tube angle and 650c wheels are employed to move the centre of gravity to a similar position in relation to the wheels - there seems to be a break-even point at a rider height of around six feet/1.83 metres tall where 700c wheels become acceptable So my question is this: If I take a road bike like a giant TCR which has very short chainstays, fit it with slightly longer forks with a more tri-appropriate offset (I am not sure what that would be)so that the head tube angle is effectively a little more relaxed and the front-centre distance is increased, and use an appropriate seatpost to get say a 76 or 78 degree angle how will this work out ? It seems that the centre of gravity issue will be resolved and the position will be something approaching a forward position. The headset will be a little high and the bottom bracket wil be a little high - allthough maybe the bar height could be addressed with bullhorn bars. As a compromise, I am interested to see how this would be. What sort of fork offset woul be appropriate -more or less than standard? - I am generally of the opinion that a slightly slower handling more straight line oriented machine is better for aerobars - not the criterium specific units that everyone seems to ride these days.
