Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Rotor Q-rings 50-36

Just bought some slightly used Rotor Q-rings 50-36. Currently I have a 50-34 crank with 11-25 cassette. Will 36-11 be much heavier than 34-11?

If so, is it possible to have only one Q-ring (the 50 one) and use my current 34 together with it? Or will this cause trouble?

The weight difference will roughly be equal to cutting your toenails before riding.

No idea on the mixing and matching though.

a 50-36 rotor is more similar to a round 52-38.....

I use 50-36 on my training bike, and 52-39 when I'm out with my team M8s/race

Now I see why this sounded like a stupid question. I wasn't asking about the weight, but if it would be tougher to climb a hill with 36-11 vs 34-11 (for my legs). Don't know if it's a big difference between 36 and 34 tooths.

The 36T is oveal....It's about the same as the 34 @ the deadspots, but compares to a ~38 at the downstroke.

Look at it as a std. 38-52 where there's been shaved off a few tooth at the deadspots.

my "don't cross chain" post continues to apply. you are not going to use the 36x11 combination. you shouldn't use the smallest two or three cogs at the back with the small ring.

I learned not to cross chain in middle school.

Why are you climbing in your 34-11 or 36-11? If you can do that why not 53-17? I understand what you are trying to get at though. For what it's worth I find climbing with my rotor rings a joy, I can keep cadance up in a taller gear for longer periods, but I'm no expert.
