Material & Finish
cnc machined 7075 Txxx Aluminum. Long-lasting construction, type II anodizing
Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38
If you wish to use other configuration it will also work, but shifting will be slower and may require more "adjustments" of front dÃ©railleur to be acceptable. Also remember that front dÃ©railleur can only accept max 16T difference between 2 chainrings – this is how Shimano and Sram designed them.
Advantages of Absolute Black Road Round chainrings:
*One of a kind look
*Super stiff design due to thicker, 5mm construction
*Bespoke Absolute Black 4 / 6 point ramp and recess shifting design shifts as crisp as original
*Finest design that provides excellent strength to weight ratio
What size should I choose?
* 34T inner chainring should be used with 50T outer ring. Use a 34T to help with spinning higher cadence and hilly terrain.
* 36T inner chainring can be used with 50 or 52T outer ring. Use a 36T if you're a strong rider or for rolling terrain.
* 38T inner chainring should be used with 52T outer ring. Use a 38T if you're a very strong rider or for flat terrain.
* 50T outer chainring â Choose this size if you ride for pleasure or sportive events. This is the most versatile and comfortable size.
* 52T outer chainring – if you race and feel strong, it’s the classic outer chainring size and a great option for experienced riders.
Remember when selecting your chainring sizes – it’s not about what others use, but about ensuring YOUR ability to maintain a comfortable and effective cadence across the terrain you ride most often. If you ride chainrings that are too large (round or oval), your cadence will be lower. This can affect your performance by prematurely tiring your legs and possibly lead to stress injury in your knee joints.
How to mount 110/5bcd round chainring:
First, you need to remove your crank from your bike. Once removed, unscrew the 5 bolts that hold two chainrings together with a T-30 torx key. Remove both original rings. Locate the new inner chainring with the triangular timing indicator positioned behind crank arm. The bolt holes on the small chainring are recessed â so the nut heads will sit flush with the surface of the chainring – these recesses should face you when mounting the bolts. Absolute Black outer chainrings have also triangular timing indicator – position this indicator behind the crank arm. If you are only changing the inner chainring – use the original bolts that came with your crank. If you are changing a pair of rings, you will need a set of regular âdouble' chainring bolts. Tighten all 5 bolts with force of about 5-7Nm. Mount your crank back to the bike. You may also need to adjust the front derailleur upwards by 2-3mm.
