Hello Geo,
Nice to know you received my wheels well. The issue with fender screw touching tyre is something due the fact Chris wrote about elsewhere here: the rims are not fully perfect centered in left-right direction vs the hubs. There are Strida owners who are said having managed to mount wider Schwalbe Marathon tires on their 18" wheels while others not, myself being one of those. Initially my plan was to order those but then managed to measure the clearance, which was too small and thus had to invest in 16" wheel set to go all the way get the Big Apple balloon tires for comfort.
With these new wheels I have minor issue on front wheel: only little press on brake level is needed to engage braking, this means I can’t utilize the parking mode with the string at end of handlebar. Adjustment on brake cable and pads ai required - later one day.
Cheers,
Markku
