The Litespeed Sirius bike is one of the lightest bikes manufactured for the public’s road use. It only weighs 14 lbs without peddles! The reason it’s so light is that the seat stays and the fork are made of “Titanium Enhanced Carbon Fiber” and the frame is made of “Titanium Enhanced Aluminum”. Besides being lighter, the titanium/aluminum frame mix produces a much more forgiving ride than most aluminum bikes while the carbon fiber/titanium mixed fork and seat stays soften the ride and remove the handle bar buzz often found in light bikes. All components are quality Campagnolo Chorus. If you are not familiar with the Italian Campagnolo Chorus, it's on the same level as Shamano Ultegra. Last fall I replaced the rear derailleur and the cassette with new ones. The cassette is an 11/32, 9 speed and the crank is the popular compact with 34/50. At the same time last fall the tires where changed to new Pirelli Cinturato 700 x 26 for an even better ride. The bike is listed as Small. I am 5' 7" and it's a good fit for me. I suppose someone 5' 2" to 5' 9" would be comfortable on the bike. I have often received praise for the top notch paint scheme Litespeed has put on this bike. It is a Super Looker. There are no dents or scratches on the bike, and the only flaw is at the top of the fork where it enters the head tube, where one of the cables has rubbed against the paint. Other wise the bike is in perfect condition. Originally the bike had an MSRP of over $3,200. The bike is ready to enjoy and needs nothing. Any Campagnolo parts I have left over you are welcome to at no additional cost. I still have the original box and could ship the bike within the US at the new owner's cost.
