Can anyone recommend a big bike bag? As in, one to take a muddy bike from the back of the car in to the house for those days when I just can’t be bothered to clean it?

Need to be big enough to fit triple clamp forks, with front wheel off. Doesn’t need to be especially well padded, as it’s really only for keeping the inevitable mud and grime at bay, as opposed to protection. So, cheap(ish), big(ish) and dirt resistant.

Anyone got any recommendations? Possibly someone using similar for a DH bike?

TIA.

I used one similar to this http://www.chainreactioncycles.com/tifosi-bike-bag-padded/rp-prod35557

(same bag, different colours) for a trip to whistler with a DH bike, spec demo 8 with boxxers, was a snug fit, but fit it did.

Give Duffbag.com a try. I have one of there gear bags to put dirty gear in. They do big bike bags that might suit your needs
