Pain while riding-is it fit(6 posts)

Or am I overweight?

Ok, when I first started riding my shoulders were sore, I happened to find this article on fit and realized I wasn't sitting on my seat properly and all of my weight was being held up by my arms. So I pushed the seat back (aft position?) THEN I noticed that I still have to occasionaly push myself up on the seat. Is that normal? I also get a lower back pain after my rides, and sometimes while I'm at home moving from a upright to laying down position. I talked to a trainer about this while I was doing her exercises and she said I needed to strenghten my core. Could this be the same thing, or do I need to readjust my seat position?

Off topic question.
Will my hybrid be ok, on the lake front during the colder months? I REFUSE to wait until next spring to start riding again. I'm so addicted to riding, I can't wait to learn about racing bikes, and buy one. Is there like, a beginners course/site that will tell me about the different kinds, and what components are and etc...... (man I sounded like Jessica Simpson w/ that line)

I can't comment on your weight.

Tipping the front of my saddle up a little bit made life easier for my shoulders.

Strengthening core muscles will help support your upper body in a good riding position and take weight off your hands and butt.

Ride your hybrid while you investigate and shop for a road bike. October, November, January and February often yield the good closeout deals in colder climates. Meanwhile stay addicted!

You can read up on ROAD bike fitting at www.cyfacusa.com.
A hybrid fits like a mountain bike, not a road bike, since it has straight bars. Most of the concepts are the same, except road handlebars greatly extend the reach, compared to straight bars.

The saddle adjustment is used to produce the desired relationship between the crank and the knees (which does affect weight balance), not to adjust the reach to the handlebars.

Since you've moved your saddle back and obtained a better weight balance, the stem may be too long. That's what different length stems are for - to adjust the reach to the bars.

Back pain can simply be the result of a lack of fitness (weak abs and back muscles). Setting the saddle too high can also cause lower back pain. Be sure that you can drop your heel several centimeters below horizontal with your leg locked out at the bottom of the stroke. This insures that there will be some bend in the knee with the foot horizontal at the bottom of the stroke during normal pedaling.

If you are sliding forward on your seat, you most likely need to raise the nose of the seat a tad. It could be your stem / top tube is too long. A quick "rule of thumb" is to look down at your front hub while you have your hands on the hoods with a relaxed bend in your elbows. It the hub is behind the tops of the handlebars then your stem / top tube may be too long. If it shadows the hub it is about right and if it is in front of the bars it may be too long.

The rule of thumb for the seat position is to drop a string with a weight on it from the bit of bone that stick out just below the knee. With the crank in the full forward position (parallel to the ground) the string should intersect the shaft of the pedal. This is just a starting point. Make minor adjustment from there until comfortable.
If you are a spinner you may want your seat forward of there, if you are a masher you may want it back from there.

Check your seat height. As a starting point take your shoes off and put your heal on the pedal. You should be able to go full down on each pedal with the legs fully straight without rocking the hipsand without raising off the seat. Again, riding styles, personal preferences, comfort will dictate minor adjustments from there.

Handlebars for a beginner should be level with the seat to a couple of inches below the seat. As you loose gut and gain flexibility, you will lower it from there. If they are already much lower than your seat this could explain your back pain. You need to make this transition to the low position slowly over time.

As far as what bike to race, it is all personal preference. Just remember, if you can't afford to break it, don't race it. Insurance does not cover racing damage (unless you bend the truth a bit with your insurance agent). The percentage increase in speed due to equipment is minimal (with the exception of aerobars and wheels). Good tires, and good aero position on the bike have a significant impact, the label on the bike has almost none.

Thanks so much for the tips. I'll check those out today and see. I do consider myself overweight, but I'm working on that. I swear in like 6 bike rides, about an hour each, my legs have shrunk. I've been riding all summer, since the end of June. Oh and I didn't neccessarily mean racing bikes, I meant road bikes. I have a lot to learn. Right now it is all overwhelming, and I don't know where to start.
