I went for the 58cm frame given that I’m about 6′1″ - or at least used to be the last time I checked. I still need to make some slight adjustments to the setup as it’s being run in given that I can tell there’s a slight difference in my riding position to the Orange, and it feels a little too upright to be comfortable on longer rides. To be honest, this is probably more due to the fact that I need to stick some bar ends on there which would give me a similar stretch position to that of the setup on my Evo2.
I’d read elsewhere that the saddle was something to replace, but for the life of me I can’t quite see why. If you’re used to being in the saddle, then it performs well and its fairly comfortable. It’s no Gel saddle, so don’t expect Saturday-night-in sofa quality, but it’s far more comfortable than any race saddle I’ve been on.
How fast is it?
Acceleration is better than my expectations. The 7005 frame remains a solid platform to put some power through in a straight line, and it can hold its own against road frames at the lights from experience. Over distance, in comparison to the Evo2, the lighter frame and bigger gears mean that I’m able to sustain a higher average speed over the same distance. Here’s the same route on the two different bikes. As you can see, the PhD was quicker on average, and I wasn’t really pushing it that day.

What about Vibration?
On the whole the road vibration isn’t all that noticeable on the front end. You can feel the road through the saddle more than you would on fat tyres, but it’s not too distracting. What’s more distracting coming from MTB territory is that all those big hills and patches of debris/crapola you’d normally ride across without thought suddenly become life threatening hotspots on skinny rims.
Anything else on the handling?
Steering is responsive and pretty light - a product of the fact that the bike is ridiculously light in its own right. In fact I’d go as far as to say that it’s pretty frisky if you’re coming from an MTB background. I was out in high winds on the way home from work on the PhD and it felt pretty skittish on the road as I avoided the inevitable Cardiff potholes (actually, it’s probably more accurate to describe them as sink holes)
Gears work OK for around here. I haven’t done Big Hill territory yet (that’s Big Hill in South Wales folks, not Alp d’Huez type Big Hill), but I suspect that the range would be pushing it on the inner front ring. It’s just about comparable to the middle ring of an MTB, so if you use granny gears a lot for climbing long drags, then you’ll probably struggle for a while until your legs get used to the different pace/power output required to drive yourself along.
That bigger outer ring is great on the flat and on the descents too, although for my riding it suits the flat better.
Can you stop as well?
Brakes are pretty good for cantis. They definitely stop the bike, but as the Kona owner’s manual says, they may not stop *you* - you’ll need to hang on and be ready to shift your weight if you need to decelerate quickly.
So in general, it’s all good. It suits my commute to work really well, and offers me just enough challenge to make it a different ride home up the hills over my trusty old Orange. I have, however, one slight problem that I need to deal with at the moment. On the supplied tyres I’ve managed 2 flats already, and have now cut a sizeable chunk out of the rear tyre thanks to Cardiff Council cutting back the Hawthorne hedges around the lanes, and then not bothering to use a road sweeper afterwards [probably a different, outsourced department :-/ ]
I reckon that a pair of Specialized Armadillos should do the trick. More on that when I can take delivery of some new tyres.
