My 2002 Sirrus Pro came with 52-42-30 chainrings and a 11/26 or 12/26 9 speed cassette, I run a 12/23.
The first thing I did when the bike was new was to flip the stem. I also went to a Ritchey Pro, 115mm. Added Performance carbon bar ends and Terry Fly seat as I don't interface well with bodygeometry saddles. The Ritchey OCR rims with bladed spokes looked trick but proved unreliable, the rear rim failed with cracks around the spoke nipples after 1800 miles. Switched to Mavic MA3 rims with Dura-Ace hubs, 32h.
