Easy mounting
Lightweight Aluminum

A tad short

Wanted this rack because of its ease of removal -- I don't prefer riding with racks unless hauling camping gear or harvesting goodies, and this rack requires no bike altering whatsoever. It mounts quickly via 4-bolt removable face plate clamp that attaches to the seatpost (would fit any diameter) and the rear of the rack has a shelf with pannier extensions to hold 'em steady. There are plenty of places to anchor bungee cords for shelf cargo.My gear does not exceed the 25 lb. recommended cargo limit so I've encountered no strength problems. I've had it loaded up with about 21 lbs. on singletrack (including panniers), and aside from the added rear weight it didn't affect handling too severely.If I could make one suggestion it would be to increase the length of the rack shelf another few inches -- my heels come within an inch of my panniers when mounted at their backmost position, a bit close for comfort.Headlands rack (similar design) built a cool hidden storage compartment inside their shelf beam, it would be sweet if the Trans-It also had this (a minor but stealthily deluxe feature). All in all, the rack is a solid performer.
