Dajia Stainless Steel Rear Expedition Rack
This is a sturdy stainless steel rack intended for loaded touring. The emphisis is on strong construction and reliability, not Grand Cru-level finish. But the sandblasted gray finish is attractive in a practical no-nonsence way. Being stainless steel, you won't need to worry about corrosion.
It's perfectly sized for 700c wheels, but can be used on 26" and 650b frames as well. There a rear light mount with holes at the standard 50mm spacing. There are pump pegs spaced at 235mm. Max load is 25kg.
Note that this rack is intended for touring frames, so if your frame has short chain stays and you have big feet, there might be heel clearance issues.
