i don't know, man! again, "fast" for me is what bike can do under a specific set of circumstances - e.g., when I want to attack or respond to attack. it's really hard for me to tell a difference just rollin' along - even at a good clip - w/out going after town lines or jumping on it because i tend to gravitate towards the same speeds regardless of what bike i'm on. it's only when i make the effort to go faster that I notice advantages/disadvantages of a certain bike/ wheel set-up/etc. if i'm not going hard, well .... then i'm not going hard. what are your wheelset/tire specs? i doubt it would make a difference because you are rolling solo and probably won't be accelerating/ decelerating too much. but, if "fast" is the game, I'd certainly give the edge to a lighter wheelset. my "fast" 650b wheelset is pretty light - H2s laced to 28h/32h velocity aeroheads with pari-motos or GB cypres - pretty lively ride, but doesn't accelerate or climb as well as my 700c set-up. my "fast" 700c wheelset is a bit lighter and sports the skinny challenge tires - it's quick. my cx wheelset are Zipp 303s and they're in a whole 'nuther league. it bears repeating that a skinny, 700c tire was the *fastest* in BQs tire tests. so, i'll repeat it: the challenge triathalon (23mm) tire was the fastest tire in BQ "real world" tire tests.

In addition to their high performance, these tires offered excellent comfort, road feel and cornering adhesion." somehow, that result always gets left out of the wider is faster discussion. anyway, given the duration/distance of your test route, you're biology on any given day is going to be a real variable. but, let us know what you find - sounds like a fun experiment! -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
