Track Geo Sizing
 

I ride a 59cm Cinelli equipe and a 58cm Langster, 56cm Gary Fisher MTB... I'm about 5' 8, 32" inseam... Looking at an Affinity frame, and a EAI Bareknuckle... Have about $350 in the used market to throw on a frame, and parts to trade towards it...
What's the smallest I could go on the aggressive geometry? And any other frame recommendations for track day? And what kind of fork? I ride with a 4 degree stem drop and major Taylor drop bars, although I'm willing to switch up the stem. Thanks!

whoa ,I am 5'8 too ... but riding a 52cm(or even 51cm) bike

Height matters very little when choosing a frame size. Top tube length is most important.

I was also asking about what stiff frames and forks to look into for a setup under $5 billsish used, already have drivetrain and a wheelset, apologize I'm on my phone and jumped into asking..

Leader Kagero worthy of purchase?

Life is crazy.

:) well, I'm picking up the kagero I believe... Think it, "fits the bill" pretty well. I'll report back once I build her up, appreciate the sentiments :p
