Rotor Cranks? What Else Is There?
Okay, so clipless may be the thing to do, after all...it all sounds logical, even if I've never felt a need for it on a regular bike. But then why aren't y'all clamoring for Rotor cranks? Just about all the arguments being made for clips (and just how did it come to be called clipless? Is this a could/couldn't-care-less kind of usage?) apply to cranks.... What else is there to this 'bent business? Sheesh, it's getting more expensive by the day! For this price, they should throw in a girl! |

The addition of a latch between the pedal and the shoe allowed the clip to be discarded--hence, "clipless." I hate that "I could care less" usage. ^^^^^^^^^^^^^^ (clip)For this price, they should throw in a girl! ^^^^^^^^^^^^^^^ They usually come with tandems. For recumbent riders it's an extra price option often available on many street corners. BTW, this is not a "clipless" post. |

For this price, they should throw in a girl! (Un-cross-posted.) Rotor Cranks have their proponents, and they're rather rabidly evangelical. (Kind of like recumbent folk.) I'm comfortable enough with my pedaling style to be uncomfortable with spending $1400+ on two sets of cranks (one for me, one so the wife can keep up). I think you should stop obsessing about how to put your bike together. Buy it, ride it, do the adjustments to fit your body and riding style. When things start to wear out, that's when you should start buying upgraded parts. BTW: riding a recumbent got me the girl. When we were dating, I put her on my Lightning (which I had bought only a couple weeks earlier). She immediately said "get me one!". So I did, and we rode them for a year before getting married. After 12½ years of marriage, we're still happily riding together. Jeff |

Because they're generally recognized as a waste of money. The limiting factor in performance is cardiovascular capacity, not the number of muscle groups that can be brought to bear on the task. Though the Rotor cranks might seem logical and might permit a slightly higher speed for a rider whose muscular development is inadequate or poorly adapted to cycling, they offer no benefit whatsoever to the cyclist whose conditioning is optimized to the task, and they add weight to the bike and inefficiency to the drivetrain. I will also note that they appear to have once again reinvented the wheel by introducing an elliptical sprocket to add another layer of gimmickry to their device. (EPrevious versions of elliptical sprockets have been the subject of much debate, with both sides claiming that the evidence supports their conclusions; one side saying they reduce knee fatigue and increase power output, the other side saying that they increase knee fatigue and do nothing important for power output. I have a set on one of my bikes. I can't really tell that they do anything more than pull on the chain when I mash on the cranks, the same as any other sprocket.) ...(and just how did it come to be called clipless? Is this a could/couldn't-care-less kind of usage?) Before the advent of clipless shoes and pedals, there were pedals with toe clips. These were a cage or cage-and-strap contraption that isn't seen much anymore. They had their own set of problems. When the cleated shoes with clamping pedals came out, they were differentiated from the others by the fact that the pedals had no toe clip, and therefore they are "clipless". What else is there to this 'bent business? Recumbent bikes have certain advantages, as you have been discovering. They also tend to weigh more than a conventional bike, they don't always work as well in every situation, and their relatively low production numbers tend to keep their prices high. If your needs for a bike are well met by a 'bent, and you've got the money to spend, there's no reason not to go that route. Not everyone would be better off on a 'bent than a regular bike, however, and a 'bent is an expensive mistake if it doesn't work out. Sheesh, it's getting more expensive by the day! For this price, they should throw in a girl! If the manufacturers had that option, do you think they would hesitate to do so?

Just about all the arguments being made for clips (and just how did it come to be called clipless? Is this a could/couldn't-care-less kind of usage?) apply to cranks... Well that isn't what pedal attachment is about. It is there to keep the foot properly placed on the pedal and to offer extra torque by pulling up in sprints and sudden steep spots in climbing hills. They do not generate more power, that being a function of aerobics, cardiovascular capacity and stored energy available in the rider's body. The Rotor Cranks concept assumes that bicycling is limited by a mechanical hurdle to get more muscular action to the rear wheel, when in fact there is no extra muscular power available. The proponents of "round pedaling" fit the Rotor Crank model and always have. Their belief that engaging more muscles in propulsion will increase output (speed) is misplaced. Performance is limited by the body, not the mechanical interface with the rear wheel, as it has been for about a century. There are always inventors who believe that something significant was overlooked and that their invention will revolutionize bicycling. None of them have done so. Mechanical improvements come along but they have not improved performance other than allow easier gear changes, better braking, reduced bicycle weight and streamlining. None of these has changed the continuous power (watts) a rider can deliver to the rear wheel. Don't forget Alenax!

Rotorcranks are pretty cool and feel really weeeeird. The first thing one notices is that the downstroke is normal, but when the crank reaches 5 o clock or whatever position, the crank feels like it's been shortened by 20 or 30mm, shooting back up the back side of the crank stroke. It also messed me up when I wanted to push down at what I thought was 12 o clock on the ascending crank, but it actually was still at 11 o clock. There was no perceived energy conversion difference, but I only gave it a test ride around the block. -- Phil, Squid-in-Training |

Most of them look like shoes from Barnum & Bailey's Bowlarama. Don't look now, but over at Payless this past week, I saw newly-arrived styles that looked like any number of cycling shoes. Right down to the impossibly narrow heel and paper-thin sole. All they needed was a little more sole stiffness, and cleat mounting holes. They were still just as fugly, too. -- Typoes are a feature, not a bug. Some gardening required to reply via email. Words processed in a facility that contains nuts. |
