Dura Ace 7850 wheels set up a clinchers..

Hello,

Recently I was able to pick up a well used set of Dura Ace 7850 C24 cl wheels at a decent price. I took them to LBS to have them checked out and trued. I wanted to set these up with traditional tubes and tires. After taking a closer look, I noticed there was rubber cement residue in the extrusion so I spent some time with some MEK and cleaned them up. Obviously the previous user must have been running these with a "tubeless" tire setup. Then I notice that the rims do not have a gasket like a traditional clincher. I know the wheels can be set up as either tubeless or tube. After reading several reviews on tubeless, I decided to go the traditional route and I ordered my tubes and tires already.

Do I need a gasket or anything else to set these up right? I do not detect anything overly sharp in the internals but just wanted to check and make sure I am not over looking anything..

any reply appreciated..

J

It's not rubber cement, it's some kind of tubeless sealant which is based on liquid latex.

What "gasket"? Are you talking about the rim strip? You don't need it one those wheels as there are no spoke holes. If you're going to use tubes i'd recommend a short strip of Velox or even electrical tape over the valve hole to protect the tube.

You can do this if you like, however, I had a tubeless Shimano wheel set, similar to these. I used them with tubes and no rim strip for over two years with no problems.
