somelse already uses on 29er? is this good for this intent?
I like mine in the 2 x 9 configuration of 27T for the small ring and 40T for the large ring. The only caveat with those is you have to have a 110/74mm BCD crank or spider (not a problem if you pick up an older pair of appropriate Race Face cranks or get Middleburn cranks which have the option of a 110/74 spider). The 3 x 9 Q-Rings come in XTR and non-XTR 4 bolt pattern 104/64mm BCD.



Too bad they're so darn expensive.:madman:

I have been using rotor rings on my XTR970 crank for a few years now, love them. I had the 23/33 on there, but left the big ring standard as I seldom use it around here.

A week or two ago a went 1X9 and am using only the 33. It has been snowey and otherwise crappy around here, so kinda slow going and not good riding conditions, but I think it will be great for what that bike is supposed to be - XC.

I highly recommend the rings, if the gearing works for you, you are somewhat limited in ring sizes that will work with 64/104. I would really have prefferred a 30 ring, but think the 33 is goon be fine. Make me stronger, right? or something like that

i need some high bucks to adquire this.... is it true its gave more 13% power in pedaling?
I've been using a 36 tooth Q-ring for a long time. I can't say if it gives me more power, or if it smooths out my stroke. Mostly because I haven't ridden round rings in so long.

However, I bought some Middleburn cranks with a 34 tooth ring to try out. I'm hoping (now that I'm switching back) that I won't notice any difference... :rolleyes:

I've been running a 33t qring on my SIR9 for a little over a year; mostly in a SS configuration and sometimes as a 1x9.

About the only thing I can say is that it smooths out the power delivery while in a SS configuration, making it easier to stay hooked up on some of the more difficult climbs. That is about the only thing I really have noticed.

I have tried the qrotors in each of the three positions and indeed the difference is significant....one way it feels much better standing, the other way it feels much better sitting. I ended up plunking it back in the middle as that seems to feel the best overall for me.

I have these on my SS and they sure make the dead zone easier to manage compared to my standard ring.

Quick clip:

Spinning the Q-Rings

I dread the time when I have to replace them however...

I've got them on 3 bikes, my mamasita, my road bike and a single on the CX bike. The scientific argument seems solid to me, but I'm no engineer. I do know that many pro road and mtb riders use them without a sponsorship. What I notice is smoother spinning and less hip flexor issues. YMMV.

i have used a 34t for quite a long time now on my karate monkey.
First in SS configuration, wich is really good for smoothing out the dead spot.
Now i use it on an alfine, the difference is less important.

I have emailed Rotor a few times, about ring sizes, but they never reply, the company obviously know NOTHING about customer service......

The only current sizes i can see are 23/33/43 for a standard 4 bolt c/set, but ive heard of 24/34/44 and 38 and 36 teeth rings from other people on forums? I asked them if this was the case and if these sizes were still available, but no reply........ideally id like a 24 and a 34 or a 36 for a 2 ring set up.

I have the "33t" on my SS and its behavior is interesting in that it does feel harder when I am laying the power down, but easier to pedal in general due to the reduced radius at the dead spot (my original chain-ring was a 33T ). Keep in mind the 33T is more like a 35T when in the "power-zone" of the stroke.

One more thing to add, is that my back pain went away from long climbs after getting the chainring.

The following links have their current rings listed + a Toll Free telephone number to call with any questions you might have. Screw email. Give 'em an old fashioned telephone call and talk.:cool:

Some of the ring sizes you mention were former sizes that they did indeed make and sell. However, the current product has been upgraded to the sizes listed. For instance, here's a link to the older rings they sold with 24/34/44 which are discounted and still in stock at some online shops:

No, that's the USA Rotor website and a USA toll free number. You could call it from the UK, but will have to pay the charge. Or if you speak Spanish, you could track down the number in Madrid.

Or just contact the UK Distributor (Velotech). Phone numbers, FAX and email are listed on the main Rotor website. By the way, that's where I bought my Q-Rings a year ago as the US Dollar was doing very well against the Pound at the time and it saved me about $100 US.

I linked the older MTB 24/34/44 rings that are still available from various online stores.
