Yesterday after my weekly practise in hill run, bang into a pothole at 50kph until the front rim got bent slightly. 
I can't pump in the air anymore, went to bike shop and they changed a new tyre for me. The brand called "Duro" <-- dunno wat the heck is this. Tyre size is 70/90 and the foreman put in a tube for me bcoz I refuse to change rim (no $$$
)
Anyway, i plan to upgrade my wheel system in a few months time, need to research on it seems i m pretty noob in brands. I wanted to have front 70/90 and rear 80/100. Which tyre brand is good? Besides this, any sport rim which is lighter than the stock? My budget is about USD100.
