I was looking at their website but could not find the info stating the offset.

I have a NSB ring on order. Hopefully it works out.

I had to ask them directly and was given the answer above.

Chromag bruh

6 mm offset. I checked my spare 28 RF and Chromag 30. The Chromag puts the chainline inboard of The Raceface

Debate? Bikes are made for riding not pushing.

This is an 11spd problem, not a RF problem.

Well, I actually spoke to RF about their cinch rings in regards to poor chainline with 1x11 setups and was told their chainline was "optimized" for Boost, although Boost wasn't even really on the scene at the time. So their chainrings provide a 51mm chainline where a non-Boost setup should really be 48-49… try the OneUp rings as they provide a much better chainline.

The SRAM 49mm chainline also has this issue, so a 49 or 51mm chainline doesn't seem to matter much. You'd have to go in further than 49mm to notice any difference. And for the record the Shimano 1x chainline is also almost 51mm (50.6mm I think). For Boost bikes RF might be the best chainline out there since SRAM Boost is 52mm and Shimano Boost is 53mm.

I've always thought your chainline should be optimized for where you spend most of your time in your cassette. For around here it's the larger half of the cassette. I'm rarely in the bottom few cogs.

I both agree and disagree.

11 speeds and the huge cogs contribute to the problem, but having a chainring that is spaced outboard doesn't help.

Ideally a chain should run straight from the chainring to the center cog of the cassette. Mine are off a cog or two which in turn gives bad alignment when in the 42t ring. This is nothing new and I know how to fix it. I am just trying to find a suitable ring for my bikes.

Cinch cranks don't lend themselves to be spaced easily. Shimano rings can be spaced over due to the use of a spider.

Frustrating for sure but as with most things bicycle related, someone finds a way to mess things up so we have to keep buying new parts in the quest for the perfect ride.

I had Shimano cranks and tried to space over the ring… It did not help.

Depending on tooth quantity it has variable offset for better chainline.

Could not find offsets listed.

Freedom of contract. We sell them guns that kill them; they sell us drugs that kill us.
