Short top tube longer stem?
Longer top tube shorter stem?
whats the min or max on stem length that you prefer? say 120mm is the norm?
On a tri bike? Long top tube, shorter stem, all else being equal.
The reason is that the longer top tube usually means a longer wheelbase and front-center dimension.
Depends on the bike and the event distance. There can be different postitions for a short time trial or an Ironman bike leg.
tribike: 90-110mm stem
Roadie: 110-130mm stem
.
I concur with this completely.
