Golly, this forum is slow. For Christmas, I bought myself a Renntec rack and the accompanying tail bag. The rack is going to work great, but the bag is really lame (anybody want to buy it?). Today, I put my new Marsee 22-liter rack bag on and it fits perfectly. I am a huge fan of Marsee items. I have a Marsee tank bag and that thing has been through the ringer (including two trips to the IoM) and doesn't have so much as a frayed stitch. This rack bag is going to get huge use! ,BK
