Good, light replacement crankset for Trek Madone?
Moderator: robbosmans
I have a Trek Madone that I'm looking to lighten up a bit. Currently have an FSA Energy crankset. Can anyone recommend a 130BCD crankset that is substantially lighter than what I have that would be compatible with my BB90 frame? I've looked at the Extralights and Lightning cranks, but they don't seem to have compatible versions.

****Pretty sure Lightning makes BB90 versions of their crank. I own both Lightning and Extralights (not in BB90), and both work well. The advantage of the Lightning is that you can get them in whatever length you need whereas the Extralights only come in 172.5 I think. The Lightnings are lighter as well (I think about 455ish grams complete or so with the 130 aluminum spider that is solid aluminum, and less for the 110 which is drilled out, or the carbon 130 TT spider..). The Extralights are not as stiff as the Lightnings, but have a really nice and narrow Q-factor which I prefer.
Both are nice cranks, and the bearings are easily serviced and/or replaced. The weights above are not exact, but pretty close. I am going by memory but have everything written down somewhere... if only I could remember where..
Ax-lightness have a version also, called press-fit for that kind of BB.
always try to be better, rider, person...

SRAM Red Exogram will be lighter and more cost effective.
