DIY Panniers - Coroplast

I wouldn't make these myself as I am pretty well invested in ones I have made in plywood, leather, or in packcloth. Lightweight plywood is interesting because it allows the racks, frames and bags to share parts for very good aero, weight and cost (but not detachable). But in the attached video (my apologies if I am the last to see these as usual, though I did a search), shows a great option for use on racks that would integrate frames and bags, and be very easy to make. It would be a natural for Tailwinding (which actually might get me making some). Downside is Coroplast was tried by HD around here, but they only stuck with it long enough to sell through the first flat, so other than elections it isn't an easy find at a good price.

Presented for those with an interest in such things, as most will just pull out a card.

Lots of Coroplast signs get thrown away right after the November US elections .. It's Free But soiled with false promises.

Hmmm...
I think I'll stick with soft-shell fabric packs.

However, I did have a piece of that tied onto my rear rack for a while. Preventing stuff on top of the rack from hitting the tire, and working as a crude fender. Many new racks, however, now come with a fender strip.

I've thought about making a framebag out of coroplast for quite a while now. I just need a bigger piece. It's only a month until the elections. I'm waiting.

Actually, I use a piece of it right now under the rack as a fender and it works quite well. Hadn't even thought of the idea of it also keeping things away from the tire.

On my old bike I use it for the front fender and a nice sized piece of it on the back on the homemade rack as basically a shelf. Hadn't thought of the idea of using it as a pannier...not sure why.

Quite often, but not always you can use duct tape, probably the stickiest stuff works best. Put the duct tape on the sign and then pull it back off removing the lettering and leaving it on the duct tape. It worked great back in 2012 but not so well in 2014. Not sure if the color of the print on the sign has something to do with it or if a little better technology toward putting the lettering on the signs has made it more difficult. Be interesting to see what happens this year.

I've got pretty low clearance on the rear rack of my old Colnago. Ancient Blackburn rack tied into Blackburn Campy dropout adapters. The rack may have been also designed for 26". So, wearing through things like a pack tied to the top of the rack has been a bit of a problem.

I also have had troubles with inadequate rear support on my racks and floppy rear panniers. Yeah, I know there are better touring racks now. For a previous trip I had taped some pegs to the rack. But, one might use the plastic cardboard stuff as a internal stiffener for floppy bags. Maybe also other internal frame/form elements.

Carradice barbags are made from coroplast. The box is held together with rivets , the Rixen and Kaul mount is rivetted on. The fabric is glued around the sides.
Carradice also use coroplast for the back and base of their canvas panniers. The mounting rail is rivetted through the canvas and plastic backboard.
It is a really tough, durable and very lightweight material for providing pannier support and I've seen nothing better.
