I am looking for new rims and thought these were pretty good. However, I have a consern - over at Nashbar it says "M121 is the rim to have when you are running 2.3 or larger tires". I currently have WTB Velociraptor 2.1 and will in time switch to Geax 2.0 tires. My question is - will this rim work with my tires? If not, can you suggest any oter economically priced rim?
