Steve: Your Presto seems to have the older style latch on the main hinge. Jur also mentioned his Yeah not needing adjustment. Mine, and joose's gripe is with the 2008 V-clamp. IMO a step backwards.

My folder-specific problems:
- V-clamp adjustment rather difficult
- Handlepost/stem won't stay put, will slip during a ride
- Slipping seatpost but Dahon.Steve is right, once you have scratches on the seatpost you can get away with looser clamping.
