Ouzo Pro / Ritchey WCS Question(3 posts)

Ouzo Pro / Ritchey WCS QuestionPsyDoc
Nov 10, 2001 8:42 AM
I have a Reynolds Ouzo Pro with a Ritchey WCS stem. Yesterday, I went to adjust my handlebar height by moving some spacers around. When I took off the stem, I noticed that the back part of the carbon steerer tube had marks on it that are "feelable" with your fingernail and match-up with angular part of the WCS stem (see poorly drawn image below). Is this typical? There are no marks on the inside of the steerer tube, which I assume would indicate that there is a crack. I am planning on calling Reynolds on Monday. When I put it all back together, I never came close to the 150 kg/cm (i.e., 130 inch pounds or 14.4nm) torque setting listed on the WCS stem. I used a torque setting of 8.0 nm or 70 inch pounds and it seems to hold just fine.

I've got the same set up but I'm afraid to look. Let us know what you find out.

I talked with Reynolds and they said not to worry about it. Apparently, Reynolds puts a layer of fiberglass around the carbon steerer and that is what is "scratched." They indicated that as long as there are not corresponding marks on the inside of the carbon steerer that I'm fine. Reynolds further stated that the WCS is a great stem for carbon steerers and they have never heard of a failure resulting from someone torquing a stem to spec's. They do not have a recommended torque setting and said to use whatever torque setting recommended by the stem manufacturer. They also said that they typically will tighten down the stem, try to move the handlebars, and then make adjustments, which seems to me could cause "scratching" of the fiberglass around the carbon steerer.
