Since I was tired of having the large handlebar bag always bear in mind that even difficult me access to the lamp, I have the porter (GT) Standit Lite bought in silver anodised (and to also equal to the matching bag). The porter is up very slim, acts not by so clunky as some others, but is very stable. I have loaded the GT with 50 kg (in the state). He held out well. The mounting hardware is included, even if they are not seen in the figure. The GT can also be mounted properly. The rods, which is attached with the GT at Saddle outer tube must be reduced slightly, depending on the frame geometry will. For me it was about 50mm. Since they are also made of aluminum, which can be a little Handyman saw easily accomplish. The mounting nuts are self-locking and is required some force them to tighten.
Between GT and tires (622-35) are about 50mm air. If you drive a Schönwetterrad without mudguards, one can certainly also a 26 "- design for a 28" - use wheel.
The weight "450 g", as stated by Amazon, unfortunately it is not. There are in fact 570 g, as the provider "mega-bikes.de" also writes on his own website.
Because now my seat tube rear light was obscured by the GT-bag, I had to even a new set. I took the "Busch + Müller TOPLIGHT Line permanent diode rear light 50mm". This fits perfectly to the GT at designated place.
I myself am very satisfied with the purchase of the carrier and can recommend it gladly.
