Jewbacca Posted November 25, 2015 Posted November 25, 2015 But the bikes are the same, one is just bigger than the other, so saying Specialized, the red one, the 29er etc means you all failed at comprehension. The same means the same. If the riders had equal ability and equal steeds, it would come down to food preparation, nutricien, hydration, fatigue, how one of them felt on the day and/or a mechanical. If they both thought they were Nino Schurter and had tan wall tires, neither of them would win because they would get a million flats. ha! But seriously, why is this thread getting so many answers?! PS I was kidding about the comprehension bit but seriously, the same.... #justsaying
igg Posted November 25, 2015 Posted November 25, 2015 The small one will always be faster, it's more aero.
Lexx Posted November 25, 2015 Posted November 25, 2015 Also depends if you are on the LCHF Dieet. According to Tim, its the best thing since Sliced Bread
NelAndre Posted November 25, 2015 Posted November 25, 2015 I thought #Evan will be fastest......no wait.......he stopped for a #EvanSmallBikeSelfie..... Drat!
Guest Posted November 25, 2015 Posted November 25, 2015 If every aspect is the same the smaller bike will be faster. F=ma
Guest Posted November 25, 2015 Posted November 25, 2015 Interesting though is the will to win. I've often wondered how guys in a race will have a mechanical. Be 2 minutes behind and then pedal their asses off to catch the lead bunch and win in the end.

xnadu Posted November 25, 2015 Author Posted November 25, 2015 Come on guys its not yet friday i would like a proper answer cause i would like to know
karma Posted November 25, 2015 Posted November 25, 2015 29r will be fastest wish it was friday already.

porqui Posted November 25, 2015 Posted November 25, 2015 And ......26ers are so last year.... and this year and next year - they just won't go away!! How many Fridays are there in a week?..There is no such thing as a proper answer.
Wez-O Posted November 25, 2015 Posted November 25, 2015 Many pro roadies actually ride frames that are slightly smaller than their fit, not because its faster, but rather for an "aggressive" style of riding. In the case of sprinters, they then have ridiculously long stems.
BDF Posted November 25, 2015 Posted November 25, 2015 Ok, There are many more variables in determining speed thank bike size and rider ability. all of them will influence the speed comparison you wish to determine. Some odf the main ones are: Flat/Incline/Decline (and grades thereof) roadRider size and massGear ratios vs wheel sizes vs rider power (influences development)Wind direction and speed (this is NB due to the different resistance levels the rider and bike sizes produce)Relative rolling resistance of tyresWeight of outer wheel circumferenceMaterial the bikes are constructed from (Flex/rigidity etc) as this determines how much energy is transferred into the frame vs forward propulsion Perhaps you could fill in some of the missing variables and I'm sure there are several Hubbers who could work out the relative speeds for you.
popcorn_skollie Posted November 25, 2015 Posted November 25, 2015 Come on guys its not yet friday i would like a proper answer cause i would like to know The truth is there is no straight answer. Too many variables. Tests have been conducted to try and answer similar questions and results are never as definitive as everyone hopes. Different tests which try to answer the same thing often end in different results becaase the variables in each test differs. For the sake of the argument lets reestablish your point of departure with a more definitive example. Two bicylces. 1. A 20 inch wheeled BMX with a single speed drivetrain and trail appropriate tyres. 2. A 29 inch wheeled hardtail, rigid fork mountain bike with a single speed drivetrain and trail appropriate tyres. Each bicycle has its frame size designed to fit the same rider (according to respective diciplines. Each bicycles single speed gear ratios will be the same. Each bicyle will be ridden by the same rider on 2 separate days on the same timed XCO course to eliminate the fatique variable. I would assume that in a test with these variables the 29er would undoubtedly be faster. However, if for what ever reason the BMX wins (perhaps the course design favours the BMX) I wouldn't be gobsmacked either.
