absoluteBLACK introduces premium Gravel - Road 110/4 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 and 46/30T crankset chainrings you can ride anywhere and climb anything. Alpine climbs will never be that difficult anymore. These special super compact chainrings are compatible with all Shimano 110/4bcd cranks making absoluteBLACK the only company on the market offering such sizes. 30 and 32T chainrings allow you to climb on your own terms with improved cadence and efficiency. 10/11/12spd compatible.
Important:
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 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.
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.

How to mount Super-Compact 46/30T & 48/32T 110/4 Oval chainrings:
First, you need to remove your crank from your bike. Once removed, unscrew the 4 bolts that hold two chainrings together with a T-30 torx key. Remove both original rings.
For 46/30T - Start by placing big chainring on the crank. There is only one way to do it. Next locate triangular mark on inner circumference on the small chainring and make sure it will sit behind the crank. Small chainring has also integrated spacers on one side. Those spacers need to enter into the crank mounting holes. 30T chainring is provided with 2x M5 bolts (Torx T-25) and 2x M7 bolts (torx T-30). Lock both chainrings in place using provided bolts and torque M5 to 4-5Nm and M7 to 5-7Nm.
For 48/32T - Same procedure applies except that 32T chainring comes with 4x M7 bolts (torx T-30) .

I had a fantastic and seamless experience of cycle delivery and it was delivered in an amazing turn around time of 2 days, since I live in Chennai, the cycle was promptly shipped in a safe and unharmed manner. The sales and support was brilliant. I purchased the NUZE S3 cycle. I got information from the cycle experts since I am a newbie. My overall experience was amazing and nothing like the other customers mentioned in this site.
Kudos to the CMB team and i will ask all my colleagues and friends to buy theirs here only.
Recently bought Road bike from CMB & I can say, I am one of the happiest customers of CMB.
My experience was really superb from booking to delivery to post-sales support.
As this was my first road bike and was unaware that pedals are not included with the cycle, which I came to know after booking. To my surprise CMB had included the pedals from their side “Fitted and ready to ride”.
Thanks CMB team.
CMB is a website which helps us to choose the right bicycle, had a hassle free experience while buying my Waltx Summit 27.5 from CMB, along with the cycle, was thrown in a host of goodies worth almost 4000, the buying experience was seamless and the cycle was delivered in just 6 days including a Sunday and this while there was a heavy downpour in Chennai, still the CMB Team showed ownership and updated and kept me informed of all the checkpoints. On delivery I found out that a accessory was broken, CMB Team arranged a replacement within few hours of sending the mail to them with pictures and video of the broken item, shows volumes about a company and its staff of providing a perfect seamless solution and ensuring that the customer always stays happy.
I have now become a permanent client of CMB and all my future cycles and of my near and dear ones will be bought from ChoooseMyBicycle only.
With an informative and easily guiding portal, CMB comes across as the most user friendly platform for cycle riders. I bought Giant ATX 2021 in March End, however I have been engaged with the portal for cycling information for a couple of months ahead of my purchase decision. CMB has guided me systematically in my cycle purchase experience that has been quite satisfying even in the Covid 19 situation which adversely affected their services. Based on personal experience, I recommend CMB, for people who intend to make an informed purchase. Also, CMB should work upon direct integration with the OEMs to eliminate the teething issues, if any, arising in executing their transitional responsibility.
Got the delivery in 5days and as said 99% assembled only pedals need to fit and handle bar needs to tighten up.. and all this is in lockdown And the service team is very responsive.
Bought a Firefox road runner pro d from the website. Happy with the product. All major installations were done by their team. Only handle bar and pedal need to fit by me. At that time my pedal was not fit it into the crank arm. When I reported the issue they have sent me the original crank arm with support of Firefox at free of cost. They have best team to support client. Advise to buyers. They will only sent product after their quality check. But there will be a 1% chance of a mistake, so record a non stop video of unboxing of your bicycle . If any problem with the product.,Then you can prove it is their fault with the video footage. In my case I was unable to prove it is their mistake . So I have to accept that was my mistake but they really amazed me by giving the original part at free of cost
