The wtb nineline tyres were great on it though.
Oooh ... CRC are doing them for £16.99 each at the moment; given that my Nano Races are starting to wear I reckon that's rather fortuitous.
The main aim of the shakedown ride is to see if I can handle the fixed + flatties combo on proper rough stuff - initial impressions are good but that's been on a 20km each-way commute and whilst York's roads are pretty bad, they're not 'bridleway' bad (yet - the council seem to be trying their damnedest to make it happen, though). If they don't work out, I'm planning to get a pair of ATAC MX8s (more foot support) and put the Saint flatties on Pugsley.
£16.99, well spotted
I was very impressed with them. They went over loose gravel, boulders (dry and slippy), tarmac, pine woodland and worked flawlessly. They grabbed well on wet cambers too. They didn't however work in 2ft deep peat bog, neither did my shoes, socks, shorts
I'm just off to get another pair.
I've just switched to flats too, but not riding fixed! I've stuck saints on and they were as grippy as spds, even on big downhill boulder sections. I never slipped off them once. Just got to remember to tilt my pedals when I jump and not do the spd lift
