On One Pickenflick

If this is the same frame layout as the old px dirty disco (which I bought for commuting) they are generally shipped with the cx rims which go well with 700 x 35 tyres but would do equally well with 700 x 28 as an on road commuter.  

If you use something like the conti cross speed they are fast rolling on road and on tracks with and without load, pretty comfy aswell.  I used those last winter, all good even on frozen pavement.  Did have the odd puncture from glass shards, but I did take a path I probably should have avoided. 

Only downsides are tough to find mudguards which fit well.  I went with a bottom tube guard (nervous about fitting certain guard to the front wheel) and an SKS raceblade XL on the back (still can catch a bit).

This year I'm going to try conti 4 seasons 700 x 28, be a bit more organised leaving stuff at work to avoid a backpack every time and only switch on the 35's if the weather gets really bad or I want to go off road.

Depends on what you want, but I'd be looking for something I could fit proper mudguards to.  If they added fittings for guards and a rear rack, they'd already have my money.

The stack is more relaxed than my CXR, reach is about the same, so I would expect it would be a good option for a relaxing ride.
