Love it. Perfect size, I attached a square open wicker basket to it, perfect for my purse, and a sweater.
Great Quality! Light weight but sturdy
350mm long x 240mm wide
Looks like the aluminum tubes have a 17.5mm diameter
Headtube mounting holes are 70mm apart. I had been hoping they they would be 64mm to match a water bottle cage but no luck.
I was surprised and pleased to find that the top of the rack has 4 threaded holes 175mm x 90mm apart. Not 100% sure yet but I think they are threaded for M4 bolts.
The rack came with 5 SS cap head bolts, 1 SS Nyloc nut and 6 SS washers. All hardware is either M5 or M6 but I haven't checked it yet to be sure. No instructions but I assume one bolt, the nut and two washers are for the headlight and the other four bolts are for threaded bosses on the headtube.
Over all I'm very happy with the rack, can't wait to get my bike so I can install it and start riding.
Perfect size, great for bike
