Reminded of this by another thread. I’ve got a couple of Duff Bags for transporting bikes around. As lead times for these things seem to have increased – I was wondering if anyone has an idea of durable, reasonably priced alternatives? I would prefer a bag where rear wheels can remain on if possible.

Try looking at Ground Effect they are in New Zealand but seem to have a bag that will meet your needs.

Canyon do a big soft bike bag for 35quid, you’ll need to take the wheels off but for the money its pretty good.

Thanks guys!
