hello guys,

Before this i train on roller (w/o resistance) to try to improve my pedaling skill better,

as time goes, i started think about ,

do i need to get a turbo trainer/a roller with resistance to improve my leg power?

and now actually i am still thinking either to get a roller with resistance or turbo trainer?..

any recommend to get which one?..

Thanks

Thanks,

riding outside is for sure, but rainy cloudy stormy windy day area always around me,

so,kinda thinking of another way to make the training more effective..

wanna ask one question about chainring

can i change 52-39t pcd130 to 52-34t/52-36t chainring ?

thanks:D

Oh okay thanks..

but if i got pcd110 crank, i can build 52-36t right?..

or the answer will be a no also?

thanks
