    Tips needed please

    Just bought a used road bike rather cheap here in shanghai. it has a 28c back and 32c front.

    one of the tires have a small hole and is exposing a little of the inner tube when inflated but the tread is still good. Is there a way to save it? both tires have tiny cracks. I would hate to throw the tires away although they are old because I just bought it.

    I would like larger tires.what is the largest width i can fit? speed is not an issue.In fact this was an impulse buy. was looking for a normal commuter and it seems to good to pass. I intend to change the handles to something more upright.

    Should I change tires and buy new tubes and tires bearing in mind that this would cost over half the price of the bike or should I change the wheel set to 26 mtb type rims and run 26 x 1.5 tires as I already have them quite a bit.

    If the casing (the fabric sidewall) is not cracked, you can probably patch the inside of the tire where the hole is. It's called a "boot" (do a forum search on that one for tons of info)... use something unstretchy like Tyvek to cover the hole from the inside, then tape it over so it doesn't move around. If the casing is bad (cracks and frayed threads) the tire's probably not safe. You'll never know how big a tire you can fit until you try - pretty easy to throw good money after bad on a cheap bike purchase though.

    Your brakes probably won't allow you to change wheel sizes though.

    What's cycle commuting like in Shanghai?

    Its by the side where the psi number is. is it ok?


    Was thinking that if i were to use a mtb wheelset, i would mod it for disc brakes. Will try to save the tire.

    Almost everyone who bikes do it either for work or to get to and from work. the roads here are very flat and easy to ride. The motorist are very mindful of cyclist because if they were to run into one, what I have seen some of them ( the cyclist) do is to sit there and create a scene. The order of things are such, pedestrian - cyclist, motorcyclist, cars in that order. Pedestrian and cyclist collision, cyclist fault and so on. They have bike lanes for bikes but certain larger roads are off limits to cyclist.

    The bikes here are cheap, I bought a MTB from an expat leaving, have a beach cruiser on the way, now this road bike ( about 18.20usd), and contemplating a classic look ladies bike. something like that

    but not as pretty, no brooks, scrap looking. The only thing stopping me is I have too many now and he wants 12.90us for it, expensive considering the road bike is 18+. I may end up putting in more cash than the bike, it needs tires and maybe a paintwork and possibly more as I tweak it. My wife couldnt ride it but I like the lugged frame.

    A particularly good "boot" that I have used for emergency repairs that have lasted hundreds of miles is simply a dollar bill folded in fours. As was explained to me, a bill is more like cloth than paper. Of course your mileage may vary (with a different currency. )
