|The XLS, disguised with On One stickers....|
Constructed from 12k carbon it's a full carbon disc cross frame that is aimed fair and square at the race-savvy cross rider. It's the sharpest feeling cross bike I've ridden with snappy handling and a very stiff response to hard out of the saddle efforts. A large (PF30) bottom bracket area contributes to this stiffness, as do the boxy rear chainstays and the tapered headtube (1.25 - 1.5") that keeps things solid upfront too.
Cable routing is all internal across the top tube with no under bottom bracket cabling to keep things clean and tidy, as well as helping to cut down on maintenance after drownings with the jet wash. The top tube itself is one of the most comfortable I've ever carried with, being unencumbered with cables and perfectly flattened to lay neatly across your shoulder. The rear disc tabs are at the rear (rather than in the rear triangle), allowing easy access too for pad fettling.
Clearance is great up front and rear, despite the 'racy' tolerances between rear tyre and bottom bracket area, and during mudfests has presented no significant problems despite some build up in that area. The absence of cantilevers and bosses more than makes up for any build up of mud there and my bike has kept working fine even when conditions are really bad.
The beefy headset, stiff bottom bracket and boxy stays mean this frame just flies under pressure - compared to alloy cross bikes I've had the difference in stiffness is startling. It's not a harsh ride on rougher surfaces, just purposeful, giving you lots of feedback about what surface conditions are like. It builds up light too - with higher end components and carbon wheels it's happily threatening sub 18lb territory and so carrying feels superb on that comfy top tube.
It's just too tempting not to make comparisons between the XLS and it's sister company's One One Dirty Disco that I've also been riding. Both are superb race bikes with surefooted handling, good behaviour in the mud and light, practical (ie robust) carbon frames. Whilst the Disco also makes for a good all-round off-road riding bike, eminently suitable for 3 Peaks duties and long off road rides alike, the XLS perhaps veers a little more toward an out and out racer, feeling sharp and edgy and just itching to be ragged round a lap.

It is worth pointing out the difference in sizing - my 56cm Disco has a longer top tube and taller head tube than my 57cm XLS which partly contributes to that planted, stable feeling compared the smaller, more chuckable XLS. It's horses for courses - I've raced both on cross laps, ridden both on long rambling off road rides, and 3 Peaks trained on both. I don't have a favourite - they both do the job, whenever and wherever. You takes your pick....
