Hello group, I have been riding a Mountain bike for about 3 years now.

I decided that I want to get a raod bike so I borrowed my mates for about 3
weeks now.
Its the right size for me.
But I find it very uncomfortable, and I get a sore back, where on the
mountain bike I did not get any back pain.

Is this normal, and will I get used to it ?

I am not sure if I should go and buy a road bike if I will always get back
pain, but like anything, maybe this is normal, and I will get used to it.
Am I right ?

Thanks for any feedback.
Bill

Lower back pain often comes from too much lateral movement in the
sacrum. Or, your hips might be rocking from side to side as you pedal.
This would be particularly noticeable on hills, where you tend to push
more. If your bike fits, you should be able to stay in position for
extended periods without any hip movement. Maybe try low cadence stuff
as well. Basically, if you get a good fit, and know the technique, you
shouldn't have a problem. When you decide to go buy a bike, check with
the list for good fit kits in your local area.
