A good quality but inexpensive track wheelset from Alex.  Nice quality, nice looking, and nicely priced.  The wheels have formula cartridge bearing high flange track hubs.  Both are fixed / free in the rear.   The rims are semi aero Alex R450 with a brushed braking surface.  So if you do run a brake they will work well.  

If your rent is expensive and you are getting nagged about all the money you spend on bike parts this is the wheelset for you.

Available in silver or black.
