Confort when riding on a road bike, is it my imagination...(7 posts)

Confort when riding on a road bike, is it my imagination...Marc in Montréal
Jun 27, 2001 9:04 AM
Hello all! After years of touring (Trek 540)I finaly bought a racing bike (Trek 5900). Same size, same saddle, same short or bib. I can ride 150 km on the 540 at 18 to 21 km/hour without problems but feel pain in the a$$$$$ after just 50 km at 28 km/hour on the 5900. Last saturday I rode 169 km on the 5900 and felt disconfort for many hours.Is it because of the geometry of the frame? The fact that I feel every single bumps on the pavement with the Sestrières wheels? Maybe it has to do with the fact that I am a small format - 1,70m (5"7')& 65 k (143 lb) and that I don't have much "bacon" in my butt? Anything I could do to make rides less painfull? N.B. It is not realy pain but heavy disconfort and it disappears less than 40 minutes after I am off the road bike. Thanks for your comments! Marc in Montréal

Dear Marc,
besides the fact that in general "racing" frames will be more responsive, shorter and stiffer than touring frames, there could be many other factors adding to your decrease in comfort. I'd try swapping the saddle with your other bike and maybe running a slightly larger tire size and see if that helps.

A couple of things you can do...First deflate the tires to about 90psi will make you go slower but you will be more comfortable. Or it could be the seat has not fully been worn in. Also you could try swapping your old wheels onto the 5900 and see how much a difference in comfortability it makes.

On the other side, you have to remember the the Trek 540 (which I am assuming is steel) wasn't as stiff as the 5900. Although the 5900 is Carbon Fiber I find that was harsh on my body. It's a combination of the tires, saddle, frame, wheels, position on the bike. But the carbon fiber is relatively stiff, and that's why people love it so much. It is a lot less harsher than other high end bikes though...

In addition you are only 143lbs plus you are short (relative to my 6'3''frame and 170). So your frame is going to be small so the road vibrations don't have the area to dissapate know what I mean?

Either's an awesome my opinion the Rolf Vector series are harsher than other wheelsets...but also I like ketchup on my eggs and not everyone does.

Hope this helps.

tires and frame, no doubt the major contributors.

Touring bikes usually come with 32-35mm tires (vs 23mm on performance)
second that Reynolds 520 frame eats all road vibration better then any road frame (even Ti) would ever do. Not that carbon or Ti cannot be made as sweet so much flex wont be tolerated on road bike.

If deflating tires won't do it pick up 28mm tires (Michelin makes sports in this size). and yes they don't roll as fast

My Selle hurt like hell for the first 500 klics, but now it's okay.
Maybe you need to give it time.
Just a thought.

Road bikes are race machines. The stuff we ride is trickle down from the pro's. They are built for one thing, speed, not comfort. If you put in long rides, the truth is things will hurt. Your butt, your feet, your back, your neck. You can mess with your set up, try different saddles, shoes, but in the long run, you will hurt somewhere. I'm good up to about 3 hrs, then after that I start to get little aches and pains here and there.
The only exception is with my butt. I rode with a Brooks Team Pro for a couple of seasons and my butt never bothered me. The trade off is weight at a whooping 540 grams.
You will have aches and pains for awhile, perhaps a couple of seasons untill your body adapts.
Yes, the sissy boys who wear lycra shorts and shave their legs are actually pretty tough when it comes down to it
Also: 169K=105 miles and your wondering why it hurt? Sorry, no ill intent directed, but what do you expect? If you don't want pain look for another sport...

The 540, even though it's aluminum, has the long chainstays and fork trail of a classic touring bike. It's designed to be stable under load, and the long wheelbase makes it more shock-absorbent than racing bikes. (The 540 may have had a chro-moly fork too, I forget). In addition, the 540 undoubtedly has fatter tires running at lower pressure than your racing bike.

All this adds up to a bike that doesn't kick you in the ass quite as hard as a whippy racing bike, whatever it's made of.

540 was a nice bike. Too bad Trek only gave it a couple of seasons before discontinuing it.
