    Yeah, don't forget to splurge for the optional chain guard.

    I’d pay a crisp $20 right out the ATM to see some twicycle riding hipster lumbersexual catch his zz top beard in that handlebar drivetrain and just get shitwhipped over the front.

    I know many of us comment on your writing in longer posts.

    But this is an amazing sentence.

    That would be fucking gold!

    Saw a set of these in the Rotor US HQ the other day. Someone had sent them in for a bearing service. The tech was like "I don't know what we're gonna do with these". They're an old attempt to eliminate the dead spot using a mechanical linkage that allows each crank to rotate forward through the dead spot independently of the other crank, or the drivetrain. WTF. So heavy, complicated, and I imagine clunky to ride. I asked the tech if they're sweet, with no hesitation he said NO. Hahahaha!

    More info on the system in here. Crazy.

    Well, there's at least one guy out there who thinks they're pretty sweet.

    I need to see an animation of that thing moving to get my head round it... Or is it just bullshit like the L shaped cranks

    It actually works. Just not a very elegant way to get it done. I am a fan of their oval rings, not sure if they're any better than the rest though. If you have their cranks though, you can clock the offset forward or back in small increments based on your own torque output. There's probably some advantage to that if you're racing at a top level. Their power meter app measures torque vectoring for that purpose.

    Found this video of it in action but the video's kinda jumpy so it's hard to see well.

    I remember seeing those when they first came out. They seemed just as dumb back then. No matter what new products Rotor puts out these days, I will forever associate that company with those things.

    Shouldn’t your legs eliminate any dead spots?

    Change in speed shown means the change in net leverage is awfully similar to their oval chainring. So hard to imagine they came up with that thing first. Or maybe it's not.

    ETA, I definitely want to try it. I have no idea why.

    I want those rotor cranks, mounted to a knolly, with a trust fork up front and a thudbuster seatpost. Aiming for the most unnecessary pivots possible. I guess it probably needs a softride stem and a fastflexx bar too.

    I think you can fit the Exycle bars on that. Can't leave out the upper body!!
