Rotor Q rings on Ultegra chainset?
Discussion
So i've worn out my chain/cassette and chainrings, so i fancied upgrading a little bit by either just getting what i assume was possible, in getting some Q rings and putting them onto my existing ultegra 6870 cranks. A new KMC chain, in gold of course, and a new ultegra cassette?
Now i have noticed that i do top out going down hills so was thinking of going from a 50/34 to a 52/36 and keeping the cassette the same 11-28. Theres about 3 different type of rotor q rings, i'm not sure which ones to get, is it worth paying a bit more and getting the rotor cranks too, if so which ones and would this require a rotor BB?
Additionally - ive had a bit of chain suck, not good on a carbon frame, do any of you use a chainsuck device to any success?
Many thanks,

Yeah, im surprised, ive only done 1300 miles on them - theyre degreased and reoiled weekly so its not a maintenance issue.
The next thing is , do i go for rotor cranks and q rings or just slap some q rings, new chain and ultegra/ duraace cassette on her... I just bought a rotor chain drop tool thingy to stop that chain suck ever happening again..

Worst chain suck I had on a bike was due to failing bearings in rear wheel, once they were replaced it stopped. Im not saying its this, but it can be due to other things
I prefer a 52/36 to a 50/34 . If you are considering moving to a 36, how do you cope with the lower end. I wouldn't bother moving just to give more speed on the downhills, but thats me
Ironically my bike with a 36/29 is fine for me and feels the same as a 34/28 even though the ratio is supposed to be a bit tougher

That's not a "Chain suck" device it's a "chain catcher" to stop your chain dropping off the smaller gear and getting stuck between chainrings and frame.If that's happening then you need to adjust the stops on your front derailleur and not spend any money on anything!
PorkRind said:
Anti-chain suck devices typically sit under the chain stays and prevent the chain pulling up from the bottom of the chainring and round the BB shell.The chain catcher will only prevent the chain dropping inside the inner ring when you shift from big > small at the front.
Edit - beaten to it.

I hope its not the bearings, but mavic aren't exactly know for their bearing quality..
Mine was just jamming up, id coast up to a junction and maybe spin the pedals once backwards for a bit of balance and then the chain would get caught up and fall off. Since the bearings were done I can pedal endlessly backwards with no ill effectsIts bread and butter simple stuff for a decent LBS , id just ask them to look at it , im s
t at gears though so avoid at all costs That’s not chain suck; that’s just guff freehub (bearings) allowing the chain to “back up” rather than rotate freely, and fall off the chainrings where there’s too much slack.
Chainsuck is the chain, well...sucking...onto the chainrings and getting dragged upwards, normally getting trapped against the chainstay. Shagged chainrings and/or chains will do this.

Regular, full degreasing doesn’t help matters: it’ll strip the grease out from around the rollers, and roiling doesn’t always get the right amount back in the right places.The next thing is , do i go for rotor cranks and q rings or just slap some q rings, new chain and ultegra/ duraace cassette on her...

Are you absolutely sure it’s chainsuck (doesn’t sound it, TBH)?
PorkRind said:
Hmm OK. It is one of those mavic ratchety free hubs that whir quite a bit so creating more resistance than say a shimano might? I think they're designed like it to engage quicker upon acceleration.
They’re just Mavic freehubs being their usual ste self, nothing to do with engagement or supposed acceleration advantages.Jimbo. said:

Yeah I agree, my issue sounds similar to OPS , was trying to get him to check everything before investing in new rings Chainsuck is the chain, well...sucking...onto the chainrings and getting dragged upwards, normally getting trapped against the chainstay.

I've tweaked the h and l. Adjustment screws so when theyre tighter tolerances between chain and mech.
How do I check / clean free hub?
The H and L limit screws won’t help here, and assuming you’re not having any problems at the back, you never need touch them once set up.How do I check / clean free hub?
What you adjusted was the B screw, and that won’t do anything at all for chain suck.
