IRO group buy: howto make it more aggresive
so yeah, I was thinking that if i go with a different fork that puts the wheel closer to the frame that would do it right?
anyone know if the carbon fiber fork offered on IRO's site has more agressive angles than the IRO group buy bike?

because he really wanted a frame with true track geometry, but couldn't resist the price of the IRO?

well since the seat tube is more slack than a track frame, maybe a 650c front wheel with the stock fork?

Changes to make it more aggressive? Proper width and positioned (not just really ****ing low and narrow) drop bars so your out-of-saddle sprints have great leverage and a good saddle position so you can really wind up your spin (slightly more forward than "usual" = better ... if unsure, experiment in .5cm increments).

Pump it full of steroids, then kick it in the head tube.

yeah, but moving the tyre closer to the frame will make it look more aggressive, but handle less aggressively. I'm throwing on an Easton EC70, with a few mm more rake (IIRC) as a test, to see if it'll quicken up the handling, making it 'more aggressive'.
And seat tube angle is overrated. steeper allows shorter chainstays, but if you use a setback post, saddle slammed back on the rails, or a straight post with saddle forwards, you are changing the angle anyway.
FI, assume a 28cm long saddle with one corner of a hypothetical triangle connected to the middle, one more to the BB and one horizontal with the ground, so it forms angle ABC (effective ST angle) with the BB.
Lets say the test whatever has his saddle at 76cm from the BB.
1. straight post with clamp in the middle of the saddle will be a 73 degree seat angle. How many people use that?
2. Setback post pegged 7.5cm behind BB.
=73.6 degrees.
3. Italian style 10cm behind bb
=71.6 degrees
4. 5cm behind bb (theoretical UCI limit) Easily achievable with a straight post because my short femurs mean I use this position
=75.5 degrees.
There you go, you can have an aggressive 75.5 (or keep pushing it up) or a slack 71.6 using the same post. Or is this another one of those fashion, not position, things.

When you get professionally fitted for a bike (a road bike, at least), they make sure your knee doesn't extend past your toes while pedalling because it supposedly causes knee problems. So watch out if you decide to slide your saddle all the way forward.
