As I know , for flat stages pros use 53-42 front crank and variations of course , for hilly stages 52-38 and smaller .

re puto.. el roza el amarillo?.. putazo mal! jaja

[roadglide]

boyBurgos....Hmmm...You mean 56 for the big chain ring and 52 foir the small chain ring...there is no crank of these sizes as you mention in your comment.

[boyBURGOS]

I've learned that tour d France bikers are using 56 for the first crank and 52 for the second. That's why they can maintain the ave. flat speed of 50 to 60kph.

@boyBURGOS haha never......

[JeDaaRe1]

@boyBURGOS No, you need power.

[ndarkened1]

@boyBURGOS No it isn't. They most often run a 53/39.

They also never average 50 kph. For example, Mark Cavendish won stage 7 of 2011 averaging 39 kph. Only when getting to the sprint do you see those intense peloton speeds.

Also, 120 rpm (close to Cavendish's sprint cadence) on a 53x11 will go 74.7 kph. More than enough and in fact faster than even Cavendish could go. Trick is simple: have powerful legs.

Also, no one makes a 52 inner chainring, just a 42 inner for TTs.

May I ask. how many teeth are there in the big front plate? 60, 65,or 70

[robertoquinto]

@boyBURGOS i believe is a 53 i don't think they use those big plates
