Looking to buy a pair of Shimano 500 or Tourney Center Pull brake Calipers, the style which has the chrome straddle wire link coming from one of the brake arms thereby eliminating the need for a separate straddle cable. Please see pics.

I would prefer the 500/600 version which is more nicely finished. I also would prefer the medium reach version, not the super long reach version (see pics)

Thanks
