• @cycleclinic I'm looking to get some IRC tyres from you for the season. Would like some that can be used for weekend rides as well as crits. It's either the roadlite or Formula Pro RBCC. What would you recommend and what size for 18mm internal rims running ultegra brakes (little clearance)?

    Appreciate the advice.

  • Roadlite tyres 25mm 340g real weight 345g claimed. real width on 17 to 19mm internal width rims 27 to 27.5mm wide and height 24mm. rolling resistance at 80 psi with 40 kg of load at 30 kph is 13.7W.

    Formula Pro RBCC
    25mm tyre 275g - real width on 17 to 19mm internal width rims 25mm and height 22mm. rolling resistance at 80 psi with 40 kg of load at 30 kph is 15.2W.

    The Roadlite roll a little faster, but the RBCC look to have some improvements and be a better tyre in general terms.

    I've not tried the Roadlite, but the RBCC are outstanding in every regard, even fitting them was a PoP.

    You don't say what series brakes you have, but I assume they're all easy to measure.

  • Trying to choose between these tyres is like trying to choose an ice cream flavour in an Italian gelateria, they're all good. The rbcc tyre though has more grip and may cut less and I think they can do more miles the 28mm rbcc is lighter than the 25mm roadlite.

    We'll see at euro bike if there is going to be a new version of the roadlite.
