That's always the case but not germane to this discussion. Of course, a strong enough rider can overcome a handicap from his bike. Chris Froome could beat almost everyone even if he were on a Walmart BSO. But we are discussing just the effect of wheel diameter and for equal riders, wheel size can effect the outcome.
