The long reach caused by the stem and bull horns may be giving you the impression that the bike's top tube is too long. The Kilo TT already has one of the shorter top tubes for a bike of a given size.
To clarify a few things blackwizard:
- when sitting on the saddle, you should NOT be able to put your feet flat on the ground. More like tip toe.
- when coming to a stop at a light, you should be able to get off the saddle and either straddle the top tube, or leave one foot on a pedal with the other foot flat on the ground to clear the top tube.
Looking at your photo, I would suggest several changes:
- Change to a shorter stem. This is the least intrusive change as it doesn't affect the rest of the cockpit.
- Shorten stem AND change to flat bars with bar ends. Bull horn bars with long stems is a recipe for a long torso and long arms. If you go with riser bars, this would reduce the distance you have to reach from seat to bars too.
- Shorten stem and change to DROP BARS. This would give flats that are close to your body for upright riding, and drops that are still within reach when riding into the wind.
