You'd be better off comparing the 58cm Pilot to the 58cm 5000 IMO. Then you can see the real differences between frames of the same size form the same manufacturer. Why try to compare the 60cm 5000 to the 63cm Pilot?
It's pretty easy to see the diefferences between the two.
Pilot = slacker geometry, longer chain stays, longer wheelbase, shorter TT, lower standover = more upright position, stability over quickness, comfort over speed, etc...
5000 = steeper geometry, shorter chainstays, shorter wheelbase, longer TT, higher standover = more aggressive position, quickness over stability, speed over comfort, etc...
Yeah the handlebar drop on the Pilot is probably less than that on the 5000 (goes hand in hand with the intent of each bike). But that's a figure that can be easily changed by swapping stems, adding or subtracting spacers, etc... So what's the big deal???
It's very straight forward what the differences in these two frames are and what the intended purpose of each bike is (IMO). I don't see why people insist on micro-analyzing the [censored] out it. There's nothing really mysterious about it at all. 🙄
