Rotor Chainsets

    Hi everyone,

    I’m considering picking up a Rotor 3D+ chainset, with normal style rings. Just wondering if anyone has any experience of Rotor cranks at all? How do you rate their stiffness against the usual suspects of Shim/SRAM/Campy?

    Probably stick these on a BSA frame (using the BB30 rotor bottom bracket), or maybe a BB86 if I like them enough. One of the attractions is that I can stick the chipset on whatever bike I fancy regardless of frame, just use the Rotor BB!

    Let me know your thoughts – or convince me to go for something different.

    Cheers!

    Hi allanj- I got mine my 3D+ from JE James for £180 (ish – can’t remember exact amount).

    That is a steal. Consider you will want to probably buy new chain rings with a second hand set!

    So I’ve ridden the Rotor on my Cross bike – have to say I love it. Will move it over to my summer bike shortly – or perhaps pick up their new one with a build in power meter. Thanks for your help everyone.

    Tricky thing with changing a
    Tricky thing with changing a crankset is whether its just the crankset or the bottom bracket that is also changed (for example if moving from SRAM to Shimano crank)? Adds in additional factors that will affect flexure.

    The most revealing example for me was switching from a Shimano tiagra 2-piece crankset to a Shimano Ultegra 6700 Hollowtech II crankset on the same frame (Specialized Tarmac SL2) using exactly the same BB (it was left installed).

    The Ultegra crank was noticeably stiffer, especially when stood out of the saddle sprinting in the big ring – this felt rock solid ‘like a platform’. The Tiagra in contrast felt ‘soft’ in the big ring. I actually switched it back to Tiagra to understand this, and that softness returned.

    Maybe of interest.

    Yes – I can feel the difference. Ok, perhaps flexible is the wrong word. But it is certainly perceptible.

    As a comparison, the 6800 Ultegra HT2 crank is rated as the stiffest crank Shimano currently make for road bikes.

    Dura Ace is considerably lighter than 6800 but more flexible.

    5800-105 is actually slightly lighter than 6800, but also more flexible (this comes from the large ring which uses a cheaper and lighter nylon inlay rather than carbon fibre used on 6800)

    Can you really feel the cranks flexing? I’m not convinced that you could, but perhaps I am wrong. May be if you track stand and bounce with the brakes full on? More likely the frame and tyres would flex before the cranks. Manufacturers but this info; “stiffer than last years model”, “stiffer than entry level” etc out their, in an attempt to differentiate their latest models, and churn the market for upgrades. They might be stiffer in a test jig, but that is academic.

    Anyway I have a Rotor Q setup on one bike, and SRAM Red on another. I can’t tell if one is more flexible. They are both stiff things that are stiff enough for me.

    Interesting thread this. Has anyone upgraded from an FSA gossamer pro on BBRight to Rotor?

    I’m thinking of swapping the FSA Omega CX on my cross bike for a Rotor 3D+ for the summer, and then moving it over to a road bike come the autumn. Both have BSA BBs – so using the Rotor BSA30, the 3D+ is usable!

    I’d be going from a 900g chainset on the cross to something more like 650g…

    let me know how it goes, I suspect I’d notice the improved stiffness more than the 350g difference myself but every little helps!

    I bought a rotor 3d+ chainset
    I bought a rotor 3d+ chainset the other week with the BB30 BSA and round rings. Its ace. Its dead light and just doesn’t flex. I love it. Its so smooth that I ended up buying a new rear cassette and chain just so i could listen to the silence.
