  • Hub rolling resistance is not a factor in how fast you go. Those shimano dura ace hubs if on good order will consume 1 to 2w at 30 mph. Changing tyres will make a big difference if the op is riding on gator skins. The problem with switching to lighter rims is i have tried and while the bike feels a bit lighter when putting power down it does not seem to translate to extra speed. My race bike has rims that are 500g each, they are deep and aero they dont slow me down.

    I will go back to my example of two wheelset both in the 2kg region.
    1) MAVIC MR601 hubs 24H on Mavic Cx14 rims (rims are 575g) these feel quick but i have race tyres on them (conti Gp4000s). So it is not rim weight that makes these wheels feel quick.
    2) ambrosio nemesis rim (465g each) on dura ace 7400/3 hubs 32F36R but with vittoria Pave tubs these feel alot slower but in i know it the tyres not the weight of the wheels. They are not very aero either.

    Saving 200g on your wheelset will make jack all difference to how fast you go. so fulcrum racing 7s will not make you much faster. The wheels are bit more aero which helps a bit but the difference will be around 10-15W at 30mph. At 18 mph thats down to less 5W maybe 2 or 3W i.e naff all.

    Your pinarello is going to be alloy frame if it like mine. Not sure when they stopped making steel frames. Old steel can be great. My race bike is a 1991 sannino (columbus genius steel tubing) and i have that kitted out with very modern kit. it feels modern and is a very quick bike but there is no way the pinarello i have is ever going to feel like that bike no matter how much i spend on it so i have not bothered.

    In short if you want ot improve the feel of your pinarello do fit conti gp4000s or vittoria open corsa tyres and see how you like it then. Try latex tubes too as they lower rolling resistance. This two changes will male a difference to how fast you ride. If you then want to change the wheels get some built using a modern wide rim rather than the narrow one the likes of mavic and shimano are using. Wider rims are stiffer and therefore spoke count can be safely dropped while still having a stiff wheel Using light thin spokes. Also wider rims improve ride comfort and road holding and this also makes a real difference to how fast you ride. Think something like grey h plus son archetypes on silver novatec a171/f172 hubs with silver sapim laser spokes 24f/28r. This is a light and stiff wheelset that will out peform all the factory wheelsets priced around £300. Changing ghe groupset will not make much difference unless you have an issue with the gear ratios.

    That what i would do if you want to improve the feel of the bike but it will cost and will it make you enjoy riding it more well that for you to decide.

    Yes, but will it outperform DT R24 Spline, which you can pick up for about £150? :-)

    1992 Treviso is Columbus GPX steel, which seems to be a hybrid SL/EL tubeset made specifically for Pinarello, although the decal also says helical reinforced so there's probably an SLX tube in there too. Should be a decent enough ride by old steel standards, probably better than my Ishiwata 022 Hirame and that's a thing of beauty and a joy forever.

    Engine determines rider velocity...

    However the OP wanted the 'zippy' senatation which I believe modern wheelsets even lower range ones will deliver.
