Your Bike Doesn't have to Hurt You!

We've been the in the bike business for a long time (since 1932 in fact) and the most common complaint about cycling is that it hurts. Okay, that's a pretty general complaint. Your bike can hurt you in many ways (not nearly as many ways as it can help you, but that's for another time). You could fall off your bike and get hurt, maybe you ride quickly up a hill and that hurts, or maybe your butt hurts every time you ride. Three different types of hurt:

  1. Physical Hurt - the kind you get when you miss a corner at 30 mph and scrape an acre of skin off your back.
  2. Good Pain - the kind of pain that might make you sore in the morning but comes from good hard work. The, "no pain, no gain" kind of hurt.
  3. Mechanical Pain - The kind of pain you get because something just isn't right. Pains that fall into this category are pains such as, shoulder pain, knee pain, neck pain, wrist pain, foot pain, and the ever popular butt pain.
We're going to talk about Mechanical pain here. The reason I call it "mechanical pain" is that it comes from your body mechanics being off (not that your local mechanic just charged you $50 for a new chain). Believe it or not, your bike should not hurt to ride. Your neck shouldn't hurt, your shoulders shouldn't hurt and your butt shouldn't hurt when you ride your bike.

Yesterday I went to Innovative Fitness here in Seattle to do a quick clinic on bicycles for their instructors. Innovative Fitness is "a personal fitness company on a mission. Leading the industry by example, our philosophies embracing lifestyle management while incorporating a team approach differentiate Innovative from professional trainers worldwide." One of the great things that they do down there is train for events. So, you go in, tell them that you want to do the STP (Seattle To Portland Classic) and they'll set you up with a schedule and workout to accomplish your goal. Cycling continues to become more and more popular so the trainers at gym needed a little more information on cycling and bicycles to better serve their customers.

So I started my clinic by asking a few questions about their clients. It soon became known that the chief complaint among their clients about riding their bikes was pain. When I told them that it didn't have to hurt to ride your bike even they looked at me like I was trying to sell them an affordable house in Seattle. They wanted to believe it, but they needed some proof. So I broke it down for them.

There are just a few reasons that you have Mechanical pain on your bike (quick disclaimer here: there are two kinds of butt pain on your bike, the kind that comes because you are a new rider, and the other from one of the things listed below. If you are a new rider, as long as the other things are covered, you just need to ride more):
  1. Fit
  2. Form
  3. Prior Injury
The number one reason, fit is the most important of the three. In fact, pain from numbers two and three can be reduced through proper fit. Fit is the most factor in purchasing a bike, new or used. Every day we get asked, "what's the best bike for me?" and the answer should always be, "the one that fits". If you go to a reputable bike shop, and stay away from the big box stores that have a few bikes, you know that you will get a quality bike. So you just need to buy a quality bike that fits you. You could pay $200 and get a great bike that fits and love riding it. Or you could pay $2000 and get a great bike that doesn't fit and never ride it. The $2000 bike might be better, but it doesn't matter if you don't ride it because it hurts.

So how do you know if your bike fits? Well first off, it won't hurt to ride. But more specifically there a just a few things you need to know and then you'll need to have a good bike shop and be able to work with the salesperson there. You should look for these things in a fitting a bike:

  1. Stand Over Height - Once a key factor in bicycle fit, stand over height is less important than it used to be. It's still important, you definitely want enough room, but with the advent of sloping top tube styles of bikes a good stand over height is easier to achieve. Nonetheless on a road bike you want to have at least an inch between you and the bike when you are straddling the bike and standing on the ground. You should have at least 2 inches with a Mt. Bike. (Pains that are addressed by stand over height: knee pain, butt pain and well, falling on the bike pain.)
  2. Saddle Height - Very important and one of the most common fit mistakes. I am convinced that everyone remembers that on their first bike they could touch the ground with both feet will sitting their bike seat. This might have worked for your old BMX or Stingray bike but it doesn't work for your new mt. bike or road bike. Today you need to have a little more balance and when you are sitting on the seat you'll be able to touch the ground with your feet but only with your toes. As you sit on the saddle (this will be easier if someone is holding you up) you should pedal backwards until one of your feet is at the very bottom of the peddling motion. Once it's there stop and make sure that your foot is parallel to the ground. When your foot is in this position you should have about a 10% bend in you knee. No more. No less. Adjust your saddle until this is achieved. (Pains that are addressed with saddle height: knee pain, butt pain, thigh pain, foot pain, neck pain, back pain and you'll go faster with the proper saddle height as well!)
  3. Reach - Reach is described by the distance between your saddle and the handlebars. It is possibly the most important fit characteristics and unfortunately the hardest to describe and measure. This is where working with your local bike shop really helps. Determining the correct reach (and any fit characteristic really) comes from a dialog between you and your salesperson. But these are things you should look for. When sitting on your saddle in the most comfortable position you should be able to reach forward and hold on to the handlebars with a comfortable bend in your elbows (5%, maybe 10%). You should also have a nice "ready" or neutral back posture. You back should not be hunched, nor should you be too stretched out. And your head should be in a position so that you can look down the road or trail with out putting stress on your shoulders or neck. (Pain that is addressed by reach: neck pain, butt pain, shoulder pain, arm pain, hand pain, wrist pain and back pain.)
Again, unfortunately we can't tell you what is correct, we can only ask you how you feel, look at your posture on the bike and make suggestions. You will end up telling us if the bike fits you or not. But if you work with a sales person knows how to fit you'll end up with a bike that fits. If it fits you'll ride it, if it doesn't fit it will hang out in the garage.

Check back soon when we talk about custom fitting and other professional fitting options.

Very nice article! Easy to read and understand for newbie!

I am a guy
Height 5.74";
Weight 166lbs;
Insteam 30 inch;
Saddle height 26.5 inch
Biking on road.

The bike store guy recommended me to use a Klein Adroit Hardtail size 16" Center to Top.

There is a 3 inch space between the top bar to my insteam.

This is the 1st time I ride a bike since 1990.

When I try to ride this bike:
First day: It hurts my butts and my palms.
Second day: I change the handle grips with softer one. Rode again, and it still hurts my butts and palms. (Maybe it bacause of my first day trial)
Third day: No cycling.
Fourth day: No cycling.

Does the bike fits me?

I wish I could tell you if it fits or not from your information. Just looking at it quickly it looks like the bike is in the right range for you. Three inches of standover height is a bit much for a bike that is to be ridden mostly on the road. I know that the Adroit has not been built for a few years and was originally built for cross country racing. So, while the bike might technically "fit" you, for the type of riding you are doing it's not really the correct bike. The Adroit, in it's original configuration, will always put more weight toward the front of the bike as it was designed as a racing bike. The Klein Adroit was a beautiful bike, but it proabably not the bike for what you are looking to do, even if it does fit as far as measurments go. Hope that helps.

my daughter's bike got stolen and a friend gave us a hand-me0down boys bike. we're trying to adjust it to fit a growing 9 year old and i think your tips will really help. and then when i'm real motivated, we'll take it to the local bike shop and have it done by the experts.
thanks.

Thanks for a great article. I wish you did house calls! I'm a new bike rider, and although my bike is the right height I think my reach is off. My arms, elbows, and hands always hurt during and after I ride. I've raised the angle of my handlebars so that the brakes are on top. I don't think it helped. Also, my seat is all the way up. What else can I do to adjust my reach? Thanks,

I wish I did house calls as well. Without seeing you on the bike it's hard to tell you what the next step would be. By what you've described it sounds like while the bike might be the right height the rest of the bike is too small for you. If you have a chance take it into a local bike shop that you trust and have them take a look at your position on the bike.
As for other things you can do to adjust your reach; you may be out of luck. Sounds like your moved your bars so you could possibly change your stem to one with more rise but I wouldn't suggest doing anything more before having someone at a shop take a look at it and you.

Hope that helps.

I am sorry to ask a rather crude question online, but I don't know who else to ask. After a 20 mile ride, it will burn when I pee. This happens at no other time in my life or after shorter rides. I am a female and this is exruciatingly painful. I am a new road biker and am sure this is not normal, how can I fix it?

Sound to me like your saddle is not adjusted properly at all! This is not normal, you are right. If the bike shop that you bought the bike from does not have a fitting service take it to one that does. In the mean time, make sure that the your saddle is at the right height and the saddle is level. The other thing you might try is a good cycling short. But most of all have someone professionally fit you on the bike. Hope that helps.

I used to ride a lot but I started getting a pain in my shoulder about 6 or so inches down my shoulder at about the edge of the shoulder blade on the left side. I can barely reach it with my right hand over my shoulder. It used to start hurting after about 50 miles and now it hurts just after a couple. It feels like someone is stabbing me with a hot knife in that one spot. I've been to doctors who don't really know what it is. I had one doc tell me that it is probably nerves being pinched due to arthritis in my neck. I don't know but I miss riding terribly and am getting fatter all the time.

Me:
27 years old
5'5"
215 lbs.

Bike:
16" Trek 4300 mountain bike with road tires.

I've gone from not riding for 15 years to riding 40 miles in the past three days. The evening following my last ride I noticed some pain in my right shoulder. (I also had some numbness in my left thumb while riding; this seemed to becomes less severe with padded mitts.) My seat height seems right as far as knee angle (very slight), and I didn't notice the shoulder pain while riding. Obviously I'm going to rest for a day or two, but what do you recommend after that? Are my handlebars too high/low? What about the seat? I'm hoping I'm just pushing myself too hard too fast.

I tried out a 13" frame before my purchase, but the bars seemed too close.

Great article but what I'm having trouble with is ball of foot and toe pain at the end of a long ride. Is my seat to forward? i'm pulling evenely (I believe). any other guidelines you can provide in terms of seat position in relation to knees and feet would be helpful.

Hi, when i ride on rocky off road i get a lot off pain after some time in the 3rd and 4th finger 2nd knuckles on either hand, this has been like this for as long as i can remember riding on rocky welsh trails. So much so that on longer rocky descents i have to stop to stretch my hands. I am only 15 so my hands are not fully grown and i am wondering if you think that this is something that will go away as my hands get bigger, or that it is a more serious problem, or my hands need to get stronger or whether i just need to alter the setup of my bike, if so what can i do to try to improve it. I'm using plush rockshox pike forks, riser bars and around a 90 mm 10 deg rise stem with hope brakes if that helps.

Any help/advise would be very very much appreciated, Will

Hi Will,

Sorry I can't respond directly so I hope you're checking back. The pain that your experiencing could be a whole host of things and might indeed go away as you grow, or you could cause a more serious problem because you are still growing. The first things that you might try is changing the set up on your bike. Maybe increase the stack height just a touch, it doesn't take much to make a difference. The other thing you might look at is the length of your brake levers. The style is to use very short levers and it may be that you are stretching your hands by trying to brake with one or two fingers will keeping the rest of your hands on the bars. Try a longer lever and moving it out a bit so that you can get more purchase on the lever when you brake. Also, and this is important, your problem sounded a little more serious so I called on a local Physical Therapist in the Seattle area to see if he could help. Here is the response he gave, "The 15 year old kid w/ 2/3/4 finger irritation is not something that can be answered over an email. It would require his attention/evaluation by his primary doc or sports MD, and then have a biomechanical evaluation of bicycle/bicyclist by a person who does bike biomechanics w/ appropriate training in musculoskeletal issues (licensed professional)". Seems that some things can not be fixed by fit alone and this sounds like one of them. Please check out Eric Moen's site www.bikept.com where you might be able to get more info. Hope this helps.

I'm a new roadie-been mtn. biking for a long time.

This is going to sound ridiculous, but here it goes. I'm 6'7", 225lbs, and my stepfather, 6'2", gave me a great road bike (sorry I don't know the size). The problem is my butt hurts. I can't ride for more than an hour. If I ride longer I have to stand up periodically to give my butt a break. If I don't do this (and this is going to sound crass) my cock and balls go numb. I bought a better seat and that has helped a bit and I read the article and tried to make adjustments accordingly-the best a tall man can do.

I'm wondering if there is anything I can do to make this bike work for me. Would a seat post that slopes backward help? Raising the handle bars? Or is it just plain silly for a 6 foot 7" man to fit on a bike meant for a 6foot2er? (They don't really make bikes my size anyway, so I am used to trying to make do-with mtn. bikes at least). Can I do anything beside selling the bike? I'm a poor social worker, so I don't really have the money to buy a bike.
