Topeak's MTX BeamRack is an awesome way to add touring capacity to bikes that won't accept conventional racks, such as dual-suspension mountain bikes. The quick-release mount clamps firmly to your seatpost and this rugged rack boasts durable aluminum construction capable of supporting up to 20-pounds with ease.

I use the produce with a bag that is to same but ban be used with other bags. Things that are great about this produce are every thing, very easy to use. Have not found anything wrong with, but make sure you have the write size bag
Bottom LineYes, I would recommend this to a friend
