Axiom Trekk Seat Collar

September 5, 2009

It's not often a seat collar can take on a such a big role.

The Trekk Seat Collar by Axiom is an excellent fix for riders who want to add a rear rack to their bicycle, but whose bikes lack the necessary eyelets. The seat collar provides two threaded eyelets that can be reached by most rear racks. The seat post clamp doesn't take on a great deal of load, so you can continue to figure your maximum load based on the recommendation of your particular rack. The only requirement for your bike is a set of fender eyelets near the rear dropouts, which most non-racing models will have.

The product is available in four sizes to accommodate most seat posts (28.6mm, 29.8mm, 31.8mm, and 34.9mm). If you are unsure about the size required for your bike, you may find it printed on the inside of your stock seat collar.

The Trekk Seat Collar is a simple and inexpensive way to add versatility to your road bike.

I used one of these to attach a rear rack on my granddaughter's bicycle. Worked out just fine!!
