    I purchased this rack along with the Axiom Lasalle Deluxe Panniers http://www.jensonusa.com/Axiom-Lasalle-Deluxe-Panniers-Pair-Black. Great pair. You'll need the Topeak MTX Dual Side Frame MTX http://www.jensonusa.com/Racks/Topeak-MTX-Dual-Side-Frame-MTX
    to keep the bags from hitting the wheel spokes.

    Took this rack with the bag on a trail ride. I ride a 29er Trek. Held up very well, I even hit a large badger hole which sent me over the front wheel, and the bike on top of me. The bag didn't fly off, the rack stayed in place. I was surprised. Great product!

    works great with the mtx bag, slides and locks on, -no tie downs needed. Comes on and off easily, without marking seat post.
