Reducing Crank Arm Length to 165 or 160mm

Pricey compared to what? In my experience, Rotor’s products are top notch in terms of quality (as you wrote), so the natural comparison is with DuraAce and Ultegra stuff.

I love that their stuff is modular, so you can replace, e. g. the axle should something to wrong. Their chainrings are also super stiff.

Aldhu Carbon cranks are $500 for arms, $55 for the spider and $205 for rings. All in $760. Compared to Dura Ace and Ultegra they are quite expensive and yes Campy and SRAM Red are right up there but they are pricey as well… That said, I feel the Rotor cranks are superior in virtually every way. As high in performance as almost any other crankset going.

Their aluminum version is cheaper and currently on Black Friday sale, as a set with chain rings they cost about 440 €. IMHO they are the sweet spot. I saw the Vegas crank arms for around 120 € (plus axle and chain rings).

Yes, thanks, I saw that. Thankfully I am not needing to spend anymore on cranks. Have used many different ones over the years. Will never use a SRAM carbon crank again, had problems with Praxis and just find the Rotor system to be superior for its modularity and flexibility in installation.

I’m 169 cm tall. My IS is 75cm - legs are couple inches shorter than my arm spread. My off road / road bikes / tandems were all 170 until a couple years ago when I started reading about testing on shorter cranks. I tried the 165 hole on my Kicker Bike and there was no change in my FTP but it instantly felt more comfortable and my preferred candence (on the low side of workout recommendations) increased. I would love to try 160 which the calculator mentioned above recommends but alas Wahoo in their infinite wisdom did not include a 160 hole and a rep told me that no other cranks are compatible with it. Since most of my training is on a Kickr bike looks like I’m stuck at 165 for a while.
