Finally be sure to check out Gravel Cyclist’s long-term video review of absoluteBLACK’s Shimano 4-bolt 46/30 chainring pairing.
The Shimano 4 bolt ones move the chain line 3mm in-board. Do these have the same problem?
@James Mitchell,
I wouldn’t say this is a “problem”, more of an intended design…but yes, they are also 2.5mm inboard.
Did you experience any issues with our Shimano rings that would make you say this is a problem? If you have an older frame or more racey road geometry, some might experience clearance issues due to tighter chainstay designs.
– Tony from absoluteBLACK
I bought the Easton EC90SL crank and the 48/32 4 bolt Absolute Black chainrings after a review of them on here. They work great, I have 2000 miles on them. But my gravel frame has a dropped driveside chainstay, and the clearance is only 3mm from the big ring. Also, if I accidentally shift into 32 front and 11 rear the chain touches the underside of the dropped chainstay. This second issue is not an effect of the 3mm inboard, rather the ovality. I’ve added some protective tape to the chainstay for the time being and will monitor closely.
Jeff, out of curiosity, what drivetrain are you running on the bike? Smart move on protective tape, which also helps with chainslap, assuming you’re using a non-clutch derailleur.
I was running a Dura Ace 9100 rear derailleur, but moved to the Ultegra RX Rear Derailleur when it was released to reduce chain slap. I’m running an 11-34 Ultegra cassette on the gravel wheels, and 11-30 on the road wheels, with a Dura Ace 11s chain.
