can someone help explain reach vs top-tube length
I have two bikes with almost same top-tube but really different effective reach:
bike 1) Reach= 423. Top-Tube=565
bike 2)Reach= 383. Top-Tube= 555
Reach=Bottom bracket to headset horizontally.
Therefore, a shorter reach bike will have less.. actual reach? If reach and stack are not matched between an old bike and a new bike, then a) reach will be too short/long needing a stem change b) stack will be too long/short, needing more/less spacers. And if you run out of stem length/go too low on the spacers, you will be uncomfortable
