I'm looking into getting back onto the track and the frames have changed since I raced 25 years ago. The Kilo/Pursuit frames often have deep aero tubing for the down tube and seat tube. If these are more aero-dynamic, can they be used for sprint and mass start races as well? This is assuming of course that the frame dimensions are adequate for different positions by swapping out the bars & stem and possibly adjusting the seat or getting a frame dimensioned for general racing but using the oval tubes. The BT bikes are considered to be very aero and seem to be used in all types of events.
Also, it seems that many track frames are Aluminum. Titanium would seem to be a lighter choice, but do most racers use AL because weight is not a major factor and AL is cheaper and easier to obtain, or does an AL frame feel better and stiffer on the track (whereas I perfer Ti on the road)?
