El Gigante

Sure - sorry about the spelling, its a trunk bag, and here's the link to Topeak products:

BTW - that's a nice Novara bag that he has, but I can see that velcro straps and/or bungee cords would get to be a tremendous pain pretty quickly.

Topeak sells a few different racks, some that mount on the seat post and others that mount directly on to the frame. I have one of the frame mounted racks, the Explorer, that the EXP bag mounts onto. Overall, I've been pretty happy with it. I'm starting to see a few small holes in the panniers where the stitching has given way - but that's after one and a half years of almost daily use. Some reviewers on REI and other sites have mentioned issues with the zippers, but I've never had a problem with them. Hope this helps.
