I read the articles and they sorta made sense.

In essence reducing weight is meaningless in return compared with lessening rolling resistance. Which now that I think about it makes sense because if you can't over come the friction then you stand still. Lessing the grip of friction reduces the energy needed to accelerate the object. Highschool physics is slowly coming back. Lessening rolling resistance comes in the form of a better rear hub. Better than my 1997 RX-100. Perhaps better tires. I am not afraid to drop money on those as the Armadillos are $60 per tire. The Armadillos were recommended by a friend that does a lot of Cycle Oregon Tours with goat head thorns and other nasty road crap.

My roadie is a Reynolds 853 steel frame. Probably 19 pounds?

@Furballi I wish I could ride that fast. My 10 mile commute one way is 50 - 55 min with no wind. However it is 90% hill climb. I start a 200 feet and climb to around 600'. This does not include the small rollers. Descend to about 20'. The return is a 6.5% grade from 25' to around 600' and then bomb down to 200' then rollers home. If it was flat it would be no problem. It ain't and that's Portland's west side.

Armadillo TPI 120 which is lower than the Krylion by Michelin 127tpi. I do not have the clearance for the City or City Pilot.
