I'm a junior cyclist/triathlete and got this as my first road bike. I like this bike and might upgrade the BB and such. I just wanted to know the estimated value of it. It has the Shimano 600 brakes and cranks and the original paint. It has dura-ace brifters and and 8 speed dura-ace cassette. It has Mavic 571/2 HG hubs laced to Mavic Reflex SUP rims. It has a Terry Butterfly TI saddle (which I really need to change). If there is any more information you need, just let me know.
