No it won't (you can use Race Blades); but it is IMO the best pacakage you can get around -- it is a lovely light and responsive bike (I haven't ridden the Pearson though).
I managed to get proper guards on mine with the stock tyres...

That's very interesting Andy.Could you give us the details or even pics of how you have done it?
TIA
Using run of the mill SKS full guards, I used the rear brazings for the support arms, popped the brake caliper off and on for the top bracket and used a pair of zip ties to make the fixing at the bottom of the seat tube. I made sure the tension on the support arms was such that there was no tyre rub before the final tightening and that's job done.
The front I didn't bother with due to the fat down tube, but it looked do-able, just laziness on my part.
No photos I'm afraid as the guards are currently residing on our bling tandem, but I'll probably buy some new ones for the Langster come the Autumn and do the same again.
I have some race blades, but given their tendency to slip didn't fancy trying them on the fixie where I'm a little paranoid of anything rubbing on the drive wheel...
