Riding position
Position is effectively identical: and sit within a few millimetres, closer than you could tell apart in a parking-lot test.
Handling & stability
A slacker stays calmer and more confident when it points downhill.
Why trail beats head angle here
Pedaling position
A steeper nudges you forward over the pedals.
Why the seat angle sets your pedaling here
What components fix
Shift the saddle about +12 mm on the rails to match the pedaling position.
