Duffbag Monster replacement – go Swiss?

I really like my Duffbag Monster but it’s now starting to fall apart. I’ve been looking around for a replacement and not found anything similar until I came across Tranzbag from Swiss Railways. Sadly, shipping is about the same cost as buying it!

Anyone know if it’s available in the UK or if there’s an equivalent (other than a mattress bag)?

Not bad but too small – Duffbag is 100cm x160cm, that’s 82cm x 130cm. My 29er only just fits in the Duffbag.

I ordered one of those Tranzbags. It’s a lot of money with shipping but it serves it’s purpose reasonably well.

My monster bag is heading the same way. Plenty of holes.  I had modified it early doors so it had better handle placement and no long shoulder strap.  I’ll be using my sewing skills to make a replacement.  The new one will be slightly bigger to accommodate my wider bars.  Going to add a few other features to make it easier to load and upload.

That’s reminds I have a DB Monster Bag unwanted Christmas present.

Its on for sale.
