The frame measures 53cm c-c. How do I determine if this was a frame specifically made for one of the GAN riders (or used by the GAN team)? The steerer tube of the fork has a sticker that has the number G8611 on it (I think). This sticker is extremely difficult to read so I am not the least bit sure of what it says. Also, there are the letters "KC" written on this sticker (easy to read). There may be some additional number on the sticker, but they are impossible to read. Also, there is the number 3 (maybe an 8) stamped into the steerer tube.
Does any of this help?
Thanks and I hope to hear from you soon.
The bike has been built up with Shimano Ultegra 9-speed (triple components). The rims are Mavic Open Pro, Continental tires, American Classic seatpost.
