question about rollers

[chaixi]

what is the different between 4.7g and 4.1g rollers??

which one is better?

if I fit in 4.1g rollers, does it will reduce the top speed ?

cheers

Not to much difference between those two weights.

You wont loose any top speed from either.

The lighter the weight the higher the bike will rev and in theory the more power/acceleration...
