I have customs problem. Must payed WAT. Already arrived. Weight 946 grams, no cuting tube. Max braking rotor 180 mm. Tyre Kenda 20x2,125 no problem, but it depends on the producer of tyre, and there was at least 1 cm of space on each side of the edges.
Excellent product, seems well made and nicely finished. No problems with fitting to bike and looks good. Arrived well packaged and got to UK distribution hub very quickly, there was a problem after that which delayed delivery but that was the fault of UK Parcel Force who made a mistake with my address.
