Does the " All Rounder" exist?

Must say i'm pretty happy with my Croix de fee. Last year I cycled to paris and toured 7 days in Devon and Cornwall, rode a few charity rides, and rode to work almost every day for the whole year and did the Rapha superross on it.

I do feel the weight a little after now buying a nice lightweight road bike but with a brooks b17 on it its like sitting on a cloud, but still with a turn of pace when needed.

Had to replace the rear hub but got a hope evo pro now for trouble re running.

Truly a swiss army bike

Condor. My friend bought his in 1993, it still runs perfectly. If you spend the extra money wisely it's an excellent investment. Remember that you'll get a fitting from a professional when you buy the bike and your choice a of components so no need to retro fit a stem, saddle, other contact points or wheels after you've made the purchase.

A single-wheel trailer could allow a bike that is suitable for all your needs except touring to perform that duty too. It can be unhitched while on tour, giving you a lightweight bike to go on off-road or climbing detours. Or you could use it at home to do the weekly shop. And most hitch up to a mount point integrated into, or held in place by, the rear wheel quick release, so don't interfere with disc brakes (although hub brakes could be a problem.)

It is a sizeable extra expense, especially since Edinburgh Bicycle Co-op seem to have stopped selling their cheap BOB-a-like. Perhaps the cheapest option, if you already have a spare wheel and pannier bags, is the Extrawheel, which probably also puts the least strain on a road bike's lightly-built rear wheel.

I have a Thorn Audax Mk3 with rear rack and mudguards. It is sturdy and comfortable (steel frame/fork), without being too heavy. I use it for commuting, light-medium touring, recreational riding, sportives and it copes with some fairly rough surfaces. A perfect compromise IMO!

On One Dirty Disco?

That guy went round the world on one...

My Ridgeback world voyage serves me well for all that. Obviously the panama if you're feeling flush.

Confy and hard wearing, 6000 miles with 2 broken spokes being only failure, both with massively overloaded rear panniers.

No, the 'all rounder' doesn't really exist - you'll have to compromise somewhere. Get a sportive type bike that could take wider tyres and rack if speed is the priority, get a tourer if touring is the priority! I don't think a cyclocross bike is it either, since you didn't mention that in your post..

The Condor Fratello was made for exactly the purpose you describe. Mine has a rack and panniers on the rear and does 150-200 miles a week of commuting plus winter rides and sportives with the rack removed. I've ridden on some horrible Sustrans paths with it and intend to do the Rapha Hell of the North on it in a few weeks time. It's a really great bike.

A Boardman Cross? I bought mine (a Boardman CX Pro 2011) after working on a Specialized Tricross whilst doing my cycle maintenance course, and not liking the inerts in the forks. My Boardman has served as a commuter here in Rome (...you think you have potholes in the UK?), did the Gran Fondo do Roma on it, full day jaunts on it in Lazio and Umbria, including Strada Bianca. yet to tour on it, but have mounted rear rack on it with no problems.

I have a Specialized tricross comp, does everything from fast rides to a long audax, can't recommend highly enough

My wife has a Specialized tricross sport which has a carrier on the back for commuting but also serves well for longer rides up and down in the Peak District so would say definitely worth a look.

Disc brakes can be problematic for touring reducing the number of suitable racks to choose from.

Perhaps a Surly Cross-Check?

Also All-City Macho Man!

Genesis Croix de Fer will quite happily do all of the above and more.
