Hello everyone: I have a set of 700c 18mm rims, and I want to convert into a 29er wheels, but I am not sure if they are strong enough to run on mountain bike. I will appreciate any help.

What model are the rims? That would help.

thats pretty thin, most Cyclecross wheels are 21mm wide. anything smaller then that. i wouldn't recommend off road.

If you want a narrow, but strong wheel for a 29er, look at building a set of Open pro's. 700c, very strong, and light.
