absoluteBLACK Oval PREMIUM Shimano 110BCD 5 Hole 2X Sub Compact Chainring Black / 48T
absoluteBLACK introduces premium Gravel - Road 110/5 oval chainrings in Sub-compact (super compact) sizes to improve your climbing and cadence. Increased Cadence is key to reducing perceived effort.
With 48/32T chainrings you can ride anywhere and climb anything. Alpine climbs will never be that difficult anymore.
These special super compact chainrings are compatible with majority of 110/5bcd cranks making absoluteBLACK the only company on the market offering such sizes.
32T chainring allow you to climb on your own terms with improved cadence and efficiency.
Size: (Mass +/-1g): 32T (32g), 48T (115g) Smaller rings are not possible in 110/5bcd
Special bolts are included with 32T (5xM5 TI)
Ovality: Optimised to each size separately. 32T - 8% ; 48T - 10.9% ; Timing of 108 -110.5° after TDC (top dead center) - Ideal for climbing. Patent Pending
Due to very special 2.5mm offset construction of BOTH chainrings towards the frame and custom bolts 32T can only work with 48T and special bolt set 48/32. (bolts included with small ring)
No other combination or mix of rings will work.
Due to special mounting construction, aesthetic bolt covers are not offered for this design
Absolute Black always recommends using a new chain when fitting new chainrings.
SRAM Yaw front derailleur compatibility
Due to the construction of SRAM Yaw front derailleurs, our Sub Compact chainrings are not compatible with them.
If you replace your Yaw front derailleur with a Shimano equivalent (there are no indexing issues between Shimano FD and SRAM shift levers) you will be able to use our Sub Compact chainrings.
SPEED AT CADENCE CALCULATION
The absoluteBLACK Sub Compact Oval 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.
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 example 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 32T chainring. They make climbing easier and exceptionally comfortable, but still retain high top speeds with 48T big chainring.
