Aerodynamics and calories
I have two unrelated questions. First, taking wind speed and direction out of the equation, at what speed does aerodynamic position take effect? When riding on some of the local hills, I can power up a few of them. It feels good to sit up on the hoods and engage my hamstrings, but am I sacrificing speed by allowing my body to drag? What is the break-even point?
Secondly, I know heart rate monitors are not accurate gauges for measuring Caloric output, but is there a range of accuracy that I could use to say to myself, I burned at least X amount of Calories on this ride? For example, if my HRM said that I burned 1000 Calories, could I say that I burned at least 850 Calories?

Crank length and height
Hi, I've been having some knee problems when I increase volume and/or intensity in my training. I worked on my flexibility but the problems continued. Since then I paid more attention to my fitting on the bike and I've noticed that I've been training and racing with 175mm cranks on both road training bike and MTB competition bike.
I'm a 22 year old male, 1.66 meters and 77cm inside leg length, MTB XC racer.
1. Are my cranks to long for me?
2. I know that a bigger lever leads to an increase of wattage, but is there an increase of power to the same energetic cost? In example: To the same heart rate, let's say 170 beats/minute, I'm riding at 300w at 95 RPM, with a 175mm crank in a 53/15 gear, to keep that same 300w at 95 RPM in a 170mm crank I'll need a lower gear, let's say 53/13 gear right? Therefore, the only "inconvenient" of a shorter crank length is that we need to put a lower gear for the same RPM's?

Recumbent biking
I'm new to the world of recumbent biking and am starting to experience some knee pain both during and after riding. I work out at a local gym three times a week, both on the treadmill and on the elliptical machines, plus do weight training, so I thought I was in good physical health before I started biking. Do you have any words of advice or thoughts on why I might be experiencing this knee pain? I originally thought that I needed stronger quad muscles, so I've been trying to increase my strength when I go to the gym. I'm enjoying the bike so much but now I'm worried I may not be able to keep riding without sustaining damage to my knees. Anything you can provide will be greatly appreciated!
I'm age 50, female, and ride the recumbent around my neighbourhood for now. I'm planning to do longer trail riding in the future.

Anti inflammatory
I'm taking a course of anti inflammatory medication for a rotator cuff shoulder injury, (diclofenac 50mg twice daily) for the past three weeks and have noticed markedly decreased performance on the bike. Symptoms are mainly longer recovery time, feeling of lead legs even on recovery rides, no "snap" out of the saddle, lower average training heart rates, and general tiredness after only an hour or so training. Could the anti inflammatory be affecting the process of muscle healing between training sessions? As I've noted that when I stop taking the medication for a few days my energy, my 'legs' and my training becomes closer to normal. The anti inflammatory is not a long term medication (just awaiting MRI results and a specified treatment) but I was curious whether anyone else had had this experience.

Tyres and wheels
I was looking at the late Sheldon Brown's gear calculator recently http://sheldonbrown.com/gears/. How is it possible, that when all other factors are equal, 700 x 23 tires will be faster than 700 x 20 tires? Wouldn't thinner tires have less of a contact patch, roll easier and be more aero?
I recently bought Ksyrium SL wheels because I wanted good stiff wheels for climbing. I've heard that box rims climb better so, after comparison with other wheels in the class, that was my choice; subsequent to that, someone told me his carbon aero wheels climb better than box wheels; since he's a more experienced rider than me, I have to question whether that is true. Would low to mid profile aero wheels climb better because they're stiffer? I've also hear that aero wheels only help if you're doing 20+ mph. Will they have any impact on performance under 20 mph?

Spinal stenosis
I'd been diagnosed with spinal stenosis approx 5-6 years ago and now a surgeon says I should have surgery with some fusion. He says I won't be any stiffer or less flexible than I am now. He, however, says he doesn't think I should be doing long bike rides as this could be causing or exacerbating my condition. This is surprising to me since most info I've been able to get says that low impact aerobic exercise is good, & they usually recommend riding an "exercise bike."
I'm not sure what his parameters are. I find that standing or walking usually results in pain after 20-30 minutes. I can ride the road bike ('06 Orca) 1-2-3 hours & usually feel better after, than before. Top of the bars are approx 2" below saddle, (shallow drop Deda 215) & I can also ride comfortably in the drops. If I sit up no hands to stretch my shoulders etc., I very quickly feel some pain in hips like when standing, but when back down on the bars I'm immediately ok. I told my shop on set-up that I'm more comfortable in the lower rather than upright stem position. This all makes sense to me & I'm of the adage that if it's painful (walking, standing, running etc.) don't do it, but if it feels good, it's ok.
I'm not looking for you to contradict what the surgeon is saying, but I am questioning the difference between an "exercise bike" and riding on the road. I see the difference in the possible "jarring" on bumps one might encounter on the road, but other than that.....? I'm confused because he also recommends walking instead, which is totally counterintuitive to me and what I've researched on this. (I will be seeking a 2nd opinion, although this guy is reputed to be "tops" in my area). I'll issue my own disclaimer in that I don't take your answer to be any specific medical advice in "my" case, but I'm curious as to what info, thoughts, and experience you might have encountered on this subject. I saw nothing in the previous comments on "recovering from spinal stenosis" that advised against riding the bike. I don't want to be in "denial," but I'm reminded of the whole "prostate scare" that arose a few years ago when some urologist claimed bike riding is destroying us all, which turned out to be bunk scientifically, & was more his own personal unsubstantiated peeve.
Thanks for a great and informative column you're running there.

Dave Fleckenstein replies:
As an aside, (and no offense to your surgeon), I generally encourage a minimum of two opinions for surgery. Techniques and approaches differ considerably among surgeons, and I have had clients who opted with a surgeon's decision not to perform surgery have excellent long term outcomes.
Hip replacement
I am inquiring as to whether it is safe or whether there are any long-term effects from cycling with a hip replacement. I love to cycle and I do long distances. I'm limited in what I can do sportswise (next to swimming). I'd appreciate some feedback or advice.
