SPEED AT CADENCE CALCULATION
The absoluteBLACK Sub Compact Oval 46T and 48T rings are large enough to reach comparable flatland speeds as their larger counterparts. This calculation shows gear combinations at 90rpm cadence, and 700c x 25mm tire.
* 46x11T combination is minimally faster than 50x12T. This is 47.5km/h (29.5mph) and is faster than 52x13T! At 100rpm it increases to 53km/h (32.9mph).
* 48x11T combination is minimally faster than 52x12T. This is 49.7km/h (30.9mph) and is faster than 53x13T! At 100rpm it increases to 55km/h (34.3mph).
As seen from the examples above absoluteBLACK Sub Compact Oval Chainrings are more than capable of reaching high top speeds when used with 11T cog. But where absoluteBLACK Sub Compact rings are in a league of their own is the small 30T and 32T chainring. They make climbing easier and exceptionally comfortable, but still retain high top speeds with 46T and 48T big chainring.
