I can't seem to find any specs for the Alex Solo rims online. I wanted to get some road tyres to replace the WTB terrainasauras that come stock on my San Jose. Will 23mm fit the rim, I would prefer 25s, but the 23s are very cheap on probikekit, so why not save the 15 bucks and get those I am thinking.
Just wanted to double check and make sure I wasn't making a bad purchase!
I never learned to ride a bike. It is my deepest shame.
If you measure the width of the rim and it is narrower than the tires (approx. 23mm) on the outside, then you are good to go. I personally use Alex DH22 (~22mm wide on the outside) rims with 700X23 tires and I have no problems.
However, if there was a reason you were going to get 25mm wide tires (rough roads? want more comfort?) then $15 is a poor reason to comprimise, IMHO.
