So I guess we have to glue our chainrings on to get them to stop creaking?

was thinking the same thing...this is what the bike industry gave us to replace 4 bolt.?.

Nice video.
My tips: Instead of the RC-1 you can try your GFs old transparent nail polish. OR:
Sell the Raceface cranks and get a new SLX 1x crankset for not much more than the RF chainring .

Loctite retaining compound will be way cheaper than the Park stuff.

+1 for SLX... I did it and never looked back and as a bonus, the comparatively dirt cheap Shimano BB lasts much longer too.

That's a SRAM GX crank with a Raceface chainring.

Great video. Keep cranking these out

to answer the riddle at the end of the video, the narrow teeth catch the chain more. this is because since they are narrower the pressure at the chain-tooth interface is higher, causing additional wear on these teeth.

On a narrow wide chainring, the big teeth are slightly conical as are the inside of the chain plates. This means that as the ring wears, they wedge themselves into the inside plates of the chain

I'll stick to my good ol' fashioned XT 8000 crank with its steel toothed chainring and leave gluing the aluminum ring on to the rest of you......

Is it recommended to do the same for Hope Cranks with their direct drive rings or spiders?
I ask as they have a locking ring rather than bolts.

@nwmlarge

I put a little bit of grease on both sides of the silver shim and the threads where the lock ring goes on and I haven't had creaking issues across two different Hope cranks on two different bikes.

The grease can be anything from wheel bearing grease to Slick Honey really. I have used both and both have worked the same.

NW rings pros:
Holds your chain slightly better... however it is useless unless you have a clutch derailer.

NW rings cons:
It lasts 1/2 than a regular ring
It cost more than a regular ring
It steals your torque with chain retention (in an industry where they measure how much watts you save shaving your legs... this should be a great involution)
Wears your chain faster -> wears your cassette faster.

Shimano did it right with the first 1x rings... all the pros, none of the cons... with the new xtr they had to fake a nw ring for the sake of sales.

I've been using a Biggie/Small ring with a road derailleur for the last 3 seasons. No clutch, no problem.

Your mileage may vary.

Thanks for sharing!

For the last 3-4 years I have used a N/W ring with clutchless medium cage 9 and 10 spd derailleurs, on a hardtail on very rocky trails. It helps enough that I was able to remove the MRP 1X and Bionicon C Guides without any chain drops.

Agreed a narrow wide is better than a nothing. I would say a clutch does more than the chainring but it certainly helps

Tech Talks are great. I'm always looking to learn from pro mechanics. Thank you, comrades!
