You can also remove the chainrings without taking out the crank and without special tools, just flip the bike upside down, remove the bolts from the small, then the large chainring and then you can slide em right over the crankarms and pedals
Thanks for this, had to buy a couple tools but swapped out my crankset to a 165mm and changed the chainrings while I was at it. Saved me from having to leave the bike at the shop for a few days and probably a higher cost than the tools.
Hello, could I directly replace my 1x 172.5mm cranks with the 600 1x or 2x 165mm? I need to use shorter cranks and only the 600 has them. Are they compatible/ interchangeable?
Well that video was good news! I've a new bike with a GRX 400 and looking at the chainring/arm it looked from the outside like it was riveted or one unit as there was no sign of an allen bolt or anything and it looks amazingly seamless like it wasn't even meant to come apart. I'd not considered they'd flipped the bolts to the inside where I couldn't see then, not seen that before. Good to know I can replace them without replacing the entire thing. But a bit of a pain you need to take it all apart to do that, I've replaced chainrings far more reasily before. And I don't have the special tool (Yet!).
I have done that and so far I don't seem to have any issues. Some adjustment on the front derailleur height is required. I have started to get a rear derailleur noise when downshifting, coming from the guide jockey wheel. Not sure if this is related to exceeding the maximum capacity of the rear derailleur by 2 teeth or the Teflon spray I have been using for it. Regardless I really like the 48T front chainring and I suppose if the big=big combo is avoided even theoretically there should not be any problems (I do find myself there from time to time if I am not paying attention).
I tried, result is not amazing. Shape of crank arm differ a bit between 800 and 600, and screws are a bit longer over GRX800. In practice it shifts, it kinda work, but I was getting some creaking sound.
Hello, great video! and very usefuk, thanks!! Just a question: I have exactly the same crankset and I want to replace with a 1x ... I am wondering if it is enough to by a 1x 40T chainrings and mount it in the very same crankset or if I need to buy a complete crankset... Do you know if the 1x and 2x craknset are compatible for exchanging chainrings? thanks
Very helpful, thanks. I think it's possible to remove the cranks without breaking the chain, just take it off the inner chain ring and let it hang while removing the cranks, then to install the cranks put the axle and chainrings into the looped chain when inserting the axle into the bottom bracket, if that makes sense.
Thanks. But would really like to see if it is possible to install a GRX 600 crank on a road bike frame with 130mm rear axle spacing. I would certainly like to be able to run 46/30 gearing and GRX front derailleur if needed for steep climbing. Haven't seen anyone address this compatibility.
Today I replaced my old crankset and bottom bracket with new bbr60 and 2x grx. I thought new bb is faulty as it was not spinning freely. I can see in your video that it does exact same thing, so that put my mind to rest now. Thank you!
Thanks a lot. Couldnt have done it woth out your video😊

This works with the large outer ring but not the small inner one. I know cos I tried it tonight! 😅

EXTREMELY helpful. thank you!
Hi! What chainrings did you replace it with?

Can you put the big chain ring (grx 810 48t), only the big one, no the small one, over this crank (grx600 46t)???
looking to do the same but no info on compatibility

Excellent tutorial video, thank you!
What bcd of this Chainring ?
Well done, as usual!
Thank you for this helpful video! My LBS had Park Tool BBT-10.2 in stock and it worked like a charm.
Succinctly comprehensive. Very helpful - thanks!

Did you have Hope threaded bottom bracket? I have the same but don't know if it is compatible with GRX which I'm looking to upgrade to
Can the chainring be removed directly without removing bottom bracket.?
Very nice. Thank you.
Super helpful vid!

Hello! I'm looking to upgrade to oval chainrings for my GRX 600.. do you have any recommendations?

Great Instructional video thanks
Thanks for your video :) just want to ask ae these compatible if I will replace to my slx m7000 crankset? or do i need to have compatible bb?
Won’t fit. These are made for 68-70mm frame width at the bottom bracket area. MTB usually are 73mm so it won’t fit.
Hello. What's the BCD size of the Chainring? Thanks!
Outer is 110
Is it possible to turn this 2x crankset to 1x or will I need to buy a new crankset
It is possible, the cranksets are the same, just the chainrings that are different.
Hi, is it the same process If you have a press fit bottom bracket?
Yes!
Thank you
Put what on the screw threads?
Anti seize compound!
@@FreeToCycle
Thanks mate. Couldn't we just use some grease?
@@itsm3th3b33 No... Use anti-seize. They are different.
A most excellent video.
