Carradice have been producing cycle luggage up in Lancashire for quite a while ... over 70 years in fact, so it's safe to say they know what they're doing. They're possibly most famous for their saddlebags, some members of the RSF are still using the same one more than 40 years on!
I think it's far to say that Carradice have perhaps been a little over looked by the mountainbike world but I think this'll change with the rising interest in off road touring ... many of their products are ideal for our purpose.
I have 2 saddle bags, a Super C (big one in pic) and a Barley. The Super C has a 23l capacity which means I can get pretty much everything required for an overnight trip in there, including a sleeping bag. The Barley is quite a bit smaller with a capacity of 7l, I tend to use it for guiding duties and day rides. You might be thinking, having all that hanging off the saddle must make the bike handle oddly - well it doesn't, you really don't notice the things there. Both have proved to be fully waterproof, the Super C even during a N to S Wales trip last August where it didn't stop raining for 4 days solid!
One really nice thing about them is the way they age. The more use and abuse they get the better they start to look, very much like a Brooks saddle. So if you're in the market for something to carry your gear go and have a look at the full range of stuff www.carradice.co.uk - it'll be something to leave to your grand kids!
