Impact Groovy Rollo Discs
Impact Groovy Rollo Discs bolt on to the Impact Groovy ISIS cranks giving the riders foot a bigger surface for peforming rolls.
The disc fits snugly between the crank and the extra-long axle bolt (supplied with discs). By extending the cranks in this way these discs greatly increase the stability for crankrolls, without having to swap your cranks for specialised flatland cranks.
These discs will fit a wide range of ISIS cranks available. So chances are they will fit your cranks. To see how they fit on different cranks have a look at the pictures above.
Always fit cranks without rollo disc first, then fit rollo disc once the crank is fully seated onto your hub. Installing your cranks with Rollo disc in place may result in damage to the rollo disc its self.
Weigh 50g (pair ex bolts).
Sold in Pairs
Complete with extra-long (25mm) bolts.
