Where can I buy a Aero V 25 Rim
I posted this question on the Bike Mechanic Forum but it seems to have disappeared. My Fuji Absolute 3.0 fell off the back of my car. Two LBS say the front wheel is shot. I brought a replacement front wheel. I would like to learn to replace a rim. Web sites give me the opinion that any similar 700 rim will do. I feel there must be more to it than that.
Could anyone tell me what sizing is needed to get a rim for replacement? Also, where can one buy such a rim? Thanks rommer25.
You need the ERD (Effective Rim Diameter), the drilling (how many spokes there are) and probably should stick with something at roughly the same width. The ERD is basically the inner diameter of the rim, and with hub flange height and spoke crossing determines how long of spokes you need.
ERD is a published value, but if you can't find it for that particular rim, you should be able to measure it. From the sound of things, your front rim, but not the back is damaged, correct? If so, measure the rear rim's inner diameter (where the spokes enter the rim) at several places and take the average, then add 1-2mm since you didn't account for the thickness of the aluminum that comprises the wheel.
Once you have the ERD, you can find a rim that has the same (or very similar) ERD. There is a certain amount of fudge factor with ERD and spokes, so you can usually go 1-2mm either way and still use the same spokes, especially with double-wall rims.
I would recommend heading over to Sheldon Brown and doing some reading on wheel building so you have an idea of the mechanics involved with wheel trueing before you launch into this project. Good luck!
I have seen several youtube videos where the person just tapes the new rim to the old wheel and changes the spokes. This is what I had in mine. However, I cannot find out what to buy and where to get it.
Many rims will work, not just that particular one. I don't have the rim, and a cursory glance across the web suggests this is an OEM rim, so you are going to need to measure the ORD yourself, as I outlined above, and you will likely not be able to find that exact rim. Find another rim that has the same ERD and is about the same width. Where to buy? Where do you normally buy bike parts? Online, I have used Jenson USA, Universal Cycles, Tree Fort Bikes, Outside Outfitters, Amazon, Ben's Cycles...the list goes on.
