Weaknesses: Not a big fan of the Miche hub with the Miche adaptor. I couldn't take the adaptor ring off so I had to order a 14 tooth to continue riding the stock Ritchie wheels. Needs 170 cranks instead of 165.
The 2004 bike replaces a 2003 frame that was a replacement for a friend's frame that I bent while borrowing the bike for track racing. The 2004 has some slight improvements over the 2003. Improved drop-outs, integrated head-set, slight change in top tube shaping. I ride the bike stock except for FSA chain rings ordered from Businesscycles in Miami. The bike is super stable under speed, sharp handling on 44 degree banking, no flex that I can feel. All around good race machine. Lot's of guys on the track now riding these bikes this year. No one even brought one to the track until the end of last season.
