All my bikes are 56 cm frames. A while back, I had a bike fit done and they recommended a 55 cm frame. That left me wondering whether 56 cm was really the right frame size for me, or whether I was better off on a 54 cm frame. This is particularly so for track frames, where a size smaller than used on a road frame is often recommended because the steeper seat tube angle lengthens the effective top tube length.
I therefore took the opportunity to hire a 54 cm track bike. I was given this 54 cm Fuji Track bike for the training session. The bike was running 48/15 gearing. Even though the Fuji Track was a steel frame, it was quite acceptable for a beginner bike.
I noticed that the wheel axel bolts had not be cut so that they did not protrude through the nuts; nor had the bottle cage bolts been removed or taped over. I was expecting to have to do these two things to get my own bike on the track.
