Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Wheel building

I have an old pair of wheel, still in good shape except for the rim and would like to give them a second life. The front wheel has 28 spokes and the rear 32. The rims are alexrims at400, I tried to find the same rims, but could only find the 32 holes version.

I'm quite new to wheel building, but would like to give it a try. What do you suggest I get to replace my rims ? If I change the rims model, I guest I'll have to change the spokes with it ?

kbenoit,

You may want to ask some of the wheel building specific questions over in the Mechanics forum. There are a number of threads there with excellent wheel building help if you search.

There are different thoughts on reusing spokes. And yes, unless the rim you change to has the exact same dimensions you would need new spokes (assuming you reuse the same hubs -- Are you going to reuse the hubs?)

As to a replacement rim -- there are many options in 28 or 32 hole. Mavic Open pro are a standard. Other options are DT Swiss R1.1 or R1.2. Velocity also offers some less expensive and solid rims like the Aerohead and Deep V. Then there are all the new carbon fiber rims as well (much more expensive).

Tell us what kind of riding you do and that may guide some feedback.

Find out the ERD of the AT400 rims and try to find a rim with the same ERD if you want to reuse the spokes. You can also use longer nipples if you find rims with a slightly smaller ERD. If not, spokes aren't terribly expensive.

ERD 600. I just re-built my friend's wheels.

Those aren't great rims, but they're decent. Open Pros are 602...depending on which direction your spokes were rounded when selected they could work rather well.

^ Considering that's only a 1mm difference in spoke length, I'd go for it.

Thanks a lot, it seems like the open pros (602) and the dt swiss r1.1 (599) are the best alternative to change only the rims. If I change for a rim with a different ERD, I'll have to change the spokes, but do I have to be concerned about the hub size ? I mean are there standards for spokes lenght such that I could end up with a rim and a hub that I cant find spokes for ?

No, you don't need to be concerned about hub size. If you change your hubs though you'll need to be concerned with spoke size.
