Add a review (form opens in right column) reviewed by jboyd122   on January 23, 2010   Pros I own the EN 321. They are much better than the stock rims that came with my 09 GF Wahoo. Lighter and sturdier. Cons none so far. Verdict I upgraded from the clunky bontrager rims that came on my Gary Fisher Wahoo when I decided to go to disc brakes. The rims are lighter and look nicer than the stock rims. They roll much smoother as well, but that could also be to the upgraded hubs.
