I've had my Ace since March and have ridden it hard. Frame has been great.
2 weeks ago I was practicing bunny hops over a curb. I got lazy and ended up dropping the rear tire right on the corner of the curb. Tire instantly deflated. I got the rim off, tube was gashed open, rim had a nice dent on the wall and broke a spoke.
The frame though, had no damage at all. So far, it's held up perfectly. I highly recommend the Sette Ace. Although... Sette is releasing a new line of bikes in September... so you might want to wait until then.
The OLD Sette was junk for sure and was straight off the shelf with no product knowledge, but seems they talked to some people who really knew bikes when they introduced the new stuff as it is Awesome. They really did it right!!! Hope they dont fall right back into the old housebrand they were a year ago?
