    have you figured out what caused the flats? and depending on how/where you've been riding, knocking a bit of paint off isn't unlikely.

    i love it when people get a new bike and shortly thereafter get a flat, then come back to me (at the shop) all pissed about it, *****ing about warranty this, and you'd better take care if it that. it's either A) they ran over something very sharp, ie nail, glass, etc, or B) a bmx bike that some kid bashed into a curb or similar with low-ish pressure and pinched it.

    //edit: there's a edit button for a reason. see, i used it.

    i was riding on pavement and had the tires set to 70 psi like the lbs mechanic told me even though the tires are rated for 50. how much is this gonna cost me and what size wrenches do i need to remove wheels with 3.8" axles

    should need 15 mm wrenches, first guess, by inflating them that much, you probably got a puncture from a spoke hole, due to the crappy stock rim strip and higher pressure. but take it apart and investigate, shoot some air into the tubes to find out where the hole is and then figure out why it happened.

    And therein lies your problem. 50 psi should be enough for pavement riding. 70 is too much when the tires are rated for 20 psi less...

    I disagree... ^^
    I run my tires at around 65-70 and they're rated for 50. Hell, MOST people I know who actually RIDE their bikes on the pavement (and by pavement I mean "street" riding, not just cruising) run high pressures too. I haven't had a single pinchflat since I've upped the pressure, and that was at the beginning of summer. If anything, the higher PSI helped his problems with pinchflating, and only would've hurt him has his casings blown, or a spoke cut thru the rim-strip.

    A paint chip? Really? Are you twelve?



    My bike has no paint, rust, dents, and liver spots. And I like that, cause I RIDE MY BIKE.

    Oh and psi should be as close to three digits as possible.

    70 is not enough, unless you "ride pavement," then its enough.

    Have the lbs you got it from go through it with you and and show you what to look for. It will be done right that way and you will also learn about wrenching on your own stuff in the process.---- Unless shops now are full of dudes like some of the guys on here who are total dick$ about new rider questions and concerns.---- And you will start to build the ever important relationship with your shop. But you or the shop won't know what's wrong till you have it apart. When I was at a shop we would always help people out that were new to the scene all the time. Besides, you gave them $900+ of your own hard work so they should be willing to show you basic bicycle maintenance. Don't go in pointing fingers though until you find out what happened.

    - On my P's first ride I got a paint chip on my top tube after a very minor bail (dropped the bike after not rolling a 180 out right). Since then I have noticed that the underside of the downtube has little chips in the paint from small rocks/gravel being thrown up by the tires. Regardless , the kind of riding your bike is made for you will be beating it up all over the place.

    Either you ran over something or the rim strip has shifted out of place.

    I have a standing record of over 30 punctures or so in one tube, he he he. I still have it...somewhere. I actually classified as my lucky tyre, erm, ironically.

    Congrats....you got your first chip! Now thrash it!!

    Dont feel bad...I got a new P2 Saturday and rode it for 2 minutes when I did a 180 and waffled the back rim. They rebuilt it Tuesday under warranty. Ill let youknow how it fairs at the park tonight! I heard the rims are S**T so I am expecting it to be a short night but I hope not. Ordering Azonics for it next week.

    Remove the cheap rim strips and use Velox rim tape.

    Replace tubes.

    Ride.

    learn how to patch. it's quicker and works as well as a new tube.
    You can even use old tubes for patch pieces...

    what threw me about this post - is the fact you did not even have the tools to work on or repair the simplest of things!! Owning a bike w/out the most basic tools is retarded.
    get a tube or patch kit, pump and any tools you need for quick repairs and BRING THEM WITH YOU. It'll save you from walkin in the future

    *note - unless you're running road tires...70psi is waaay to high
    Honestly... ahh I give up

    Bikes are all metric too...

    DH tubes are overkill. I've been running ultralight tubes in XC tires pumped up to 80. They used to be in Holy Rollers at 70.

    allright. i know this is probably a stupid arse noob question so im sporting a flame suit will 4130 chromo bicycle tubing rust enough to affect the structural integrity of a frame. should i worry about fixing the nicks and scratches on the bb and downtube of my bike or forget all about em and ride? i figure my bikes gonna take a good beating and get plenty scratched up

    As much as I hate to advocate the use of this tool... You don't have an adjustable wrench?

    Chromo is steel. Steel rusts.

    Yes...17mm for the axle nuts for rear (sometimes 15mm for front - usually cheaper wally world and kids bikes)
    as for protecting the steel...keep it dried and maybe use some wax on the bare metal from time to time (carnuba, paraffin et al)
    Honestly... ahh I give up

    If your hub/axle is the same as my 08, your hub will use a 15mm come wrench too. A cone wrench is basically a super thin open end wrench made to fit the thinner nuts.

    Over the many years of riding, even the ones where you are 8 years old and leave your bike outside and ride in the rain all day, I don't recall ever seeing a small paint chip show rust on the bare metal. My toptube has a chip a little smaller than a dime and has smooth bare metal showing and it doesn't have any rust on it. It happened almost a year ago too. If you want to be safe you can just coat it with something, but I wouldn't worry too much. Your bike will see alot worse in the near future. I wouldn't fret too much about it.

    Cromoly will rust... even high quality tubing. I've seen Nemesis frames with rust. I've seen plenty of bikes with rust around chips. I've seen the inside of bottom bracket shells full of rust.

    There are different things that you can spray down the seat tube to prevent corrosion from the inside.

    You can apply it to just inside the seat tube and BB shell. That's where water is mostly likely to make it's way in. Doesn't matter how much you dismantle it... you're going to have a hell of a time getting it in the stays... and all the way through the TT and DT.

    I've seen BMX bikes left outside that rust very quickly. I've seen BMX bikes from the 80s that are still pristine. It has to do with care.

    Rust is a protectant. Once there it seals the surface. It won' t destroy the frame. That is why there are 30 year old steel frames that have been stored outside still cruising about without issue.

    We aren't riding on salted roads so it won't be eaten like a car.

    False.

    Oxidation on a aluminum frame will protect it from oxidizing further.

    Iron oxide is different. It can oxidize all the way through. Any iron mass will eventually convert completely. Iron(II) will form a passivation layer. Iron(III) will flake off and expose fresh metal to be affected.

    Some steel alloys are more resistant to rust than others.

    Wrenching on a bike is not the same as wrenching on a car or dirt bike. And you don't have many tools... and there are many part specific tools.

    Learn to work on changin' a tire - and go from there...
    maybe try posting in the Beginners (possibly Tooltime) section for further assistance - as this is more of a learning issue than something specific to Urban/DJ/Park. Many more resources to be had there for sure

    How old are you Skoobey? You seem really niave (sp?) You take this a tad too serious and will is having way too much fun with you. He just loves the opportunity to flex his knowledge. Don't get me wrong he knows his stuff and does help riders out from time to time.

    I have chips all over my 20 and it has surface rust and I keep it indoors. Now I ride the ish out of it and don't wipe it down so the rust is an added plus. Gives it character. So go ride your bike and quit acting like a douche.

    I'm guessing 15. I didn't say you were or were not a veteran or guru of some sort. Really I said just go ride your bike. You'll learn everything you need to know in due time. Like as you break things you'll learn how they work, how to install em or maintain them. Like your tubes at this point.

    don't worry about the scratch! i have owned many steel bikes and some aluminium bikes. one of my steel bike is about 10 years old. it has rust on it and it hasn't broken yet. Don't treat your bike like s**t. have some common sense. don't treat it like crap and all will be fine. in my experience steel frame last longer. aluminium fatigues and cracks a lot quicker than steel rusts (as long as its treated ok) even bikes that are left outside and treated like absolute crap last years and years.
