I've been considering purchasing a Boardman Pro CX Cyclocross Road Bike Large 2010. (Broken link replaced with Google search)

The spec says the wheels are 700C and that it comes with 700 x 35C tyres. I'm wondering, should it be also possible to fit some thinner road tyres with sizes 700x20c, 700x23c or 700x25c?

Yes, you can! It looks like that bike comes with Mavic CXP23 rims, which can fit down to 19mm tires I think. You would defiantly have no problem with 700x23 tires. I'm surprised it comes with 35, that seems a bit wide for those rims, but you should be OK.

    Agreed that 35 seems way wide for that rim. I would think it would feel really squirmy in turns.

  • As cyclocross is so often a muddy sport any extra squirm from tyres is negligible! Seriously though I know a few people who have Boardmans and no one is complaining about squirmy tyres.

  • FWIW, in that price bracket I would (and did) look seriously at the Ridley Crossbow (or the X-bow as they're branding it for '11). Although if you're buying from Halfords, I assume it's because of the Cycle to Work, in which case you might not have the flexibility.

  • Mount those tires with defiance and abandon.
