What is the advantage to a 1 1/8" steerer over a 1" steerer, if any. Also, I'm considering buying a Viner Steel bike and I'm concerned about it flexing. I'm 240lbs but want a comfortable ride.:confused:

More strength, stiffness and more bearings to take the load.

Have you ever broken a steerer tube, I think not, if you use King headsets you won't ruin bearings either. I feel they went to 1 1/8" because they had to increase sales. I've been riding 1" for years and years without problems. I do like the 1 1/8" tubes and threadless stems and headsets for ease of maintenance, but the 1" stuff is fine, I would buy a bike with a 1" if I liked the bike otherwise.

The extra bearing surface is useful for very short steerer tubes.
The extra stiffness is useful for extra long ones, or for bikes which are ridden heavily, such as tandems, fully loaded tourers, or downhill bikes.

The extra stiffness of wider steerer is neccessary if you are using a low modulus, low-density material such as Al or Ti.

1" is fine for for normal road riding on a steel steerer.

What is the limit to how many spacers can be put on a one inch steel steerer tube? I have 1 1/4". Is that too many?
