    Shimano RS-80 internal rim width?????

    Researching for a new wheelset and want to go with the wider rim width for my 25mm Conti's. I like the many great reviews of the RS-80's but can't find any info regarding the internal rim width dimension. Shimano lists the outside at 20.8mm but nothing for the internal.

    Anyone know this measurement?

    Thanx

    I have the wheelset and took the measurements with a digital micrometer +-.02mm.

    My front rim is bent from a huge pot hole (so I have them sitting around with no tires) and I think was helped by a crappy truing job by the LBS. I true my own wheels now. I don't think they put them back to the correct tension. Before that they were a solid set of wheels.

    I ran 25mm Michelin Pro 4 Endurance tires on my old bike with these rims and they worked good. My Cervelo will not allow me to run 25mm tires. If you can find a good deal on 23mm rims I would probably go for them, if they are around 1500g they are as light as the RS-80s. I want to go to a 23mm rim in hopes of a little better ride with my 23mm tires. I think 23-24mm rims with 25mm tires should ride amazing with the lower pressure you can run.
