Mine is probably my favorite bike, the one that I couldn't live without. She's seen several front racks and cranksets over the years, but the overall drivetrain has stayed the same. Drops with barcons connected to a rapid-rise rear derailleur. Perfection.

Mine was spec'd out with the correct MB5 build, but the frame sticker shows the MB4's triple butted Tange tubing. Comparing my bare frame to another '5 leads me to believe the tubing sticker is correct.
