Good afternoon all
I am the proud owner of a new Look 566 , unfortunatly after only a few rides I have rear wheel puncture resulting in a decent sidewall nick.
I am noe considering upgrading the tyres and would like your views on trye size.
The origonal tyres are 23 mm , the bike is built for comforte 1st and speed second so there is already a good level of comfort.
Would you stick with the 23 mm or go 25mm , I want to speed it up a little rather than increase comfort.
any advise will be very much appreciated
regards
ILG

    You won't notice any difference in speed between 23mm and 25mm. Comfort is dependant on tyre pressure with the advantage going to 25mm as they can run lower pressures than 23mm without a greater likelihood of a pinch flat.

    23mm Michelin Pro4 Service Course and latex inner tubes. They are the perfect summer "club rider" tyre in my opinion and latex tubes make a huge difference to the way a bike rides.
    Red bikes are the fastest.

    My new 25mm tyres are vastly more comfortable than my old 23mm ones at the same pressure though so I would definitely recommend moving up in size.

    25mm Pro4 Endurance versus 23mm Gator Hardskin.

    Probably because your new tyres are actually 27mm and are actually supple (Gator feels like wagon wheels).

    Yeah. I wonder whether there is much of a difference between the Endurance version that I have and the Service Course that are a little lighter?

    I've ridden both. No perceptible difference in regards to puncture protection but I do have a preference for the SC as they feel quicker.

    So, best bet would be a supple 25mm then - Vittoria Open Corsa CX 25's?

    I have a Look 585 and Pro4 25mm are too tight for comfort - any bit of grit that sticks to the tyre grinds against the brake caliper or bridge. I don't know about your 566 but you might want to play safe and get 23mm. Difficult one because the 25mm are quite nice as I've put them on my other bike.

    To be honest I was thinking about this , I have been told that 25s will fit but it looks as though it will be tight.
    Ps I have run 25s on another bike and when removing/refitting the wheels it was a hell os a struggle to pass the brake pads even when fully open , is this normal ?
    thanks again for the replies

  • I ride with 25mm tyres on my look 566, no problem at all, not even close to being too tight for the frame!

    it wheel depend on rim width also though - do your wheels have 23mm or wider rims?

    For a fast summer, dry weather tyre yes. But they're fragile.

    The Pro4 SC are a good all round "fast" tyre that have decent P protection.
