Why are MTB top tubes so long? I’m 5’9” and a ride and 54cm road bikes with 54.5-55 top tubes and TT/Tri I look for 52-53cm top tubes. All the MTB bikes I’ve looked at MED 17-18in all have 57-58.5cm top tubes, is this normal, is the object to use a shorter stem or should I step down a size. Everyone I have talked to says go for the MED frames the SM will be too small. Just curious what others are riding around my height. Any help will be greatly appreciated.
Thanks,
