Giant TCR Advanced By : rich 17 July 2004 0 Cycling Jan Ulrich's Bike. This is a Giant TCR Advanced with an integrated seat tube so you don't actually need a seatpost or clamp. That makes it just 900 grams and you save 125 grams on the seat post and clamp. Wow. Share this:TweetPrintPocketEmailLike this:Like Loading...
