Because with all those integrated cranks you can't adjust chainline!mk00 said:why you cant leave 2 rings at M970 for example?...it needs to buy rings separately, but M970 is great I think...
They've been made for the masses, rather have a slightly heavy crankset that can cope for all weights that one thats going to splinter for guys over 100 kgs/ 220 lbs.nikoli8 said:Why so heavy
If that's true then it might be worth the extra weight.Hand/of/Midas said:fastest shifting rings in the world.
But how does your Lightning crank perform in the mud and how do those custom chainrings shift?nino said:Another downside of XX-cranks is the custom BCD of the chainrings! Limited chainring choice, heavy and expensive...i don't like this approach!
Right now i'm trying to convince the guys from Lightning Carbon do offer a double-specific 64/104 spider for their carbon cranks. That's the most used BCD these days and you have a wide variety of lightweight rings to choose from.
Anyway - when i compare my Lightning Carbon 27/40 crankset (522g complete) with the XX crank i have a smile on my face
I would like to know this also, I am wanting to put a hollowgram on my scott genius (73mm) So what is the weight of the adapters?limba said:If that's true then it might be worth the extra weight.

I have another question, what about using Cannondales Hollowgram crankset with the adapter for non BB30 frames? Would it be heavy once you add the adapter?
PM Eliflap and see if he has a weight for the whole system. I know he will have pics of the hollogram set up.yamapro said:I would like to know this also, I am wanting to put a hollowgram on my scott genius (73mm) So what is the weight of the adapters?
BS depends on bike chainline second if works on three it works on two...nino said:Because with all those integrated cranks you can't adjust chainline!
With 2 chainrings you need to shift the rings to the middle which isn't doable with those cranksets.You need a specially designed spider which places the rings in the correct position or you need "old" style cranks with separate BB where you can change BB lenght to get the correct chainline.
Just taking out 1 ring on a integrated triple crank isn't giving you the optimum. Proper double cranks offer perfect chainline so you can use ALL gears on the cassette without having the chain too crossed (eating away the drivetrain and your precious leg-power).
And people looking at climbing 3000 ft at plus 12% grade, on switchbacks.Dan Gerous said:XTR's next redesign will have a double... and I'm guessing a lot of companies will embrace doubles now with wider range 10 speed cassettes from SRAM and soon Shimano. 2x10 will be mainstream, 1x10 will become what 2x9 is/was, 3 rings will be for clydesdales...
I'm not too surprised by the heavy weight. Any (real) weight on the BB30 version?
