This is mine. I believe it's a 2004 Sirrus Sport Disc. I got it super cheap and had these part's on hand. The only things original are the frame and fork along with the headset and seatpost collar. I "updated" it to Shimano Ultegra 6600 10s drivetrain and shifter's with Deore XT cranks. It also has TRP HY/RD caliper's that have the short throw lever conversion with interrupter brake levers for feeling safer on the tops. The stem and bars are an old Ritchey WCS stem and Easton EAX70 bars. Also put a Terry Fly TI saddle and old Deore seatpost I polished up. It's a pretty fun all around bicycle.
