Is there really much difference between 700cx23 and 700cx25 tyres

    Price was certainly a factor when i bought the CD+, along with wanting minimum level 5 PP. At around £10 a hoop at the time, i considered them a great deal. They were also the Reflex ones. Clearance at Chain Reaction i think.
    Good to know the difference between CD+ and MG, and although mileage is not a big deal to me, if there's not a lot in the price between them, i'll try MG next time.

    When I swapped from Conti gp4000s 23's to 25's the ride definitely felt slightly less harsh and a bit more comfortable.
    As others have remarked is it the slight extra width or lower pressure......not sure? You could believe what the experts say or not.
    As for speed......no idea, I would imagine its how good your legs are on the day.

    You get extra volume from a 25 over a 23, but if you ride through a damp patch and then look at the mark the tyre leaves on the dry the contact patch is the same width.

    You need the extra pressure to prevent 'pinch flats' on skinny tyres so you can't just run those less inflated.
